 SFAR No. 27-5  [Removed.  55 FR 32861, Aug. 10, 1990]

   EDITORIAL NOTE: For the convenience of the user, the removed text is set
 out below.

 SFAR No. 27-5--Fuel Venting and Exhaust Emission Requirements for Turbine
     Engine Powered Airplanes

   Section 1  General Requirements. (a) This SFAR provides for the approval or
 acceptance by the Administrator of the FAA or the Administrator of the EPA of
 testing and sampling methods, analytical techniques, and related equipment
 not identical to those specified in this part. Before either approves or
 accepts any such alternate, equivalent, or otherwise nonidentical procedures
 or equipment, the Administrator of the FAA or the Administrator of the EPA
 shall consult with the other in determining whether or not the action
 requires rulemaking under sections 231 and 232 of the Clean Air Act, as
 amended, consistent with the responsibilities of the Administrator of the EPA
 and the Secretary of Transportation under sections 231 and 232 of the Act (42
 U.S.C. 7571, 7572).
   (b) U.S. airplanes. This SFAR applies to civil airplanes that are powered
 by aircraft gas turbine engines of the classes specified herein and that have
 U.S. Standard Airworthiness Certificates.
   (c) Foreign airplanes. Pursuant to the definition of "aircraft" in 40 CFR
 87.1(a), this SFAR applies to civil airplanes that are powered by aircraft
 gas turbine engines of the classes specified herein and that have foreign
 airworthiness certificates that are equivalent to U.S. Standard Airworthiness
 Certificates. This includes only those foreign civil airplanes that, if
 registered in the United States, would be required by applicable Federal
 Aviation Regulations to have a U.S. standard airworthiness certificate in
 order to conduct the operations intended for the airplane.
   Pursuant to 40 CFR 87.3, this SFAR does not apply where inconsistent with
 an obligation assumed by the United States to a foreign country in a treaty,
 convention, or agreement.
   Sec. 3  Relation to 40 CFR Part 87. (a) Reference in this regulation to 40
 CFR Part 87 refers to Title 40 of the Code of Federal Regulations, Chapter
 I--Environmental Protection Agency, Part 87, Control of Air Pollution from
 Aircraft and Aircraft Engines (40 CFR Part 87), originally issued on July 6,
 1973, and published in the Federal Register (38 FR 19088) on July 17, 1973,
 as revised effective January 31, 1983 (47 FR 58462), as amended effective
 January 20, 1983 (48 FR 2716).
   (b) This SFAR contains regulations to ensure compliance with certain
 standards in Environmental Protection Agency (EPA), 40 CFR Part 87. If EPA
 takes any action, including the issuance of an exemption or issuance of a
 revised or alternate procedure, test method, or other regulation, the effect
 of which is to relax, or delay the effective date of any provision of 40 CFR
 Part 87 that is made applicable to an aircraft under this SFAR, the new
 relaxed EPA requirement, upon its effective date, is incorporated into this
 SFAR and supersedes the provisions of this SFAR that are based on the
 provisions of 40 CFR Part 87 that were relaxed by such action.
   (c) Unless otherwise stated, all terminology and abbreviations in this SFAR
 that are defined in 40 CFR Part 87 have the meaning specified in that part,
 and all terms in 40 CFR Part 87 that are not defined in that Part but that
 are used in this SFAR have the meaning given them in the Clean Air Act, as
 amended by 42 USC 7401.
   (d) All interpretations of 40 CFR Part 87 that are rendered by EPA also
 apply to this SFAR.
   (e) Consistent with subsection (c) of this section, the following
 definitions apply:
   (1) "Administrator of the FAA" means the Administrator of the Federal
 Aviation Administration or any other officer or employee of the Federal
 Aviation Administration to whom the authority involved may be delegated.
   (2) "Administrator of the EPA" means the Administrator of the Environmental
 Protection Agency and any other officer or employee of the Environmental
 Protection Agency to whom the authority involved may be delegated.
   Sec. 5  Additional EPA approvals and procedures. (a) If EPA, under 40 CFR
 87.3(a) approves or accepts any testing and sampling procedures or methods,
 analytical techniques, and related equipment not identical to those specified
 in EPA Part 87, this SFAR requires a showing that such alternate, equivalent,
 or otherwise nonidentical procedures have been complied with, and that such
 alternate equipment was used to show compliance, unless the applicant elects
 to comply fully with 40 CFR Part 87.
   (b) If the Administrator of the EPA after consultation with the
 Administrator of the FAA, prescribes special test procedures for any aircraft
 or aircraft engine that is not susceptible to satisfactory testing by the
 procedures in 40 CFR Part 87, this SFAR requires a showing that those special
 test procedures have been complied with.
   (c) Wherever 40 CFR Part 87 requires agreement, acceptance, or approval by
 the Administrator of EPA, this SFAR requires a showing that such agreement or
 approval has been obtained.
   Sec. 7  Relation to State and local regulations. (a) Pursuant to 42 U.S.C.
 7573, no state or political subdivision thereof may adopt or attempt to
 enforce any standard respecting emissions of any air pollutant from any
 aircraft or engine thereof unless that standard is identical to a standard
 made applicable to the aircraft by the terms of this SFAR.
   (b) If EPA, by regulation or exemption, relaxes a provision of 40 CFR Part
 87, no state or political subdivision thereof may adopt or attempt to enforce
 the terms of this SFAR that are superseded by the relaxed requirement.
   (c) Consistent with Sec. 87.6 of 40 CFR Part 87, if the Administrator of
 the FAA determines that any emission control regulation cannot be safely
 applied to an aircraft, that provision may not be adopted or enforced against
 that aircraft by a state or political subdivision thereof, even if it is in
 this SFAR.
   (d) If any provision of this SFAR is rendered inapplicable to a foreign
 aircraft as provided in 40 CFR 87.3(c) and section 1(b) of this SFAR, that
 provision may not be adopted or enforced against that foreign aircraft by a
 state or political subdivision thereof.
   Sec. 9  Petitions for rulemaking and exemption. (a) Notwithstanding Part 11
 of the Federal Aviation Regulations (14 CFR Part 11), all petitions for
 rulemaking involving either the substance of an emission standard prescribed

   Landing. (a) The landing distance must be determined for standard
 atmosphere at each weight, altitude, and wind within the operational limits
 established by the applicant in accordance with Sec. 23.75(a) of this
 chapter. Instead of a gliding approach specified in Sec. 23.75(a), the
 landing may be preceded by a steady approach down to the 50-foot height at a
 gradient of descent not greater than 5.2 percent (3 deg.) at a calibrated
 airspeed not less than 1.3 VS1.
   (b) The landing distance data must include correction factors for not more
 than 50 percent of the nominal wind components along the landing path
 opposite to the direction of landing, and not less than 150 percent of the
 nominal wind components along the landing path in the direction of landing.
   (d) In lieu of compliance with section 28 of Appendix A of Part 135 of the
 Federal Aviation Regulations, comply with the following:
   Fatigue evaluation of flight structure. Unless it is shown that the
 structure, operating stress levels, materials, and expected use are
 comparable from a fatigue standpoint to a similar design which has had
 substantial satifactory service experience, the strength, detail design, and
 the fabrication of those parts of the wing, wing carrythrough, vertical fin,
 horizortal stabilizer, and attaching structure whose failure would be
 catastrophic must be evaluted under either--
   (a) A fatigue strength investigation in which the structure is shown by
 analysis, tests, or both, to be able to withstand the repeated loads of
 variable magnitude expected in service. Analysis alone is acceptable only
 when it is conservative and applied to simple structures; or
   (b) A fail-safe strength investigation in which it is shown by analysis,
 tests, or both, that catastrophic failure of the structure is not probable
 after fatigue, or obvious partial failure, of a principal structural element,
 and that the remaining structure is able to withstand a static ultimate load
 factor of 75 percent of the critical limit load factor at VC. These loads
 must be multiplied by a factor of 1.15 unless the dynamic effects of failure
 under static load are otherwise considered.
   (e) In lieu of compliance with section 32 of Appendix A of Part 135 of the
 Federal Aviation Regulations, comply with the following:
   Doors and exits. The airplane must meet the requirements of Secs.  23.783
 and 23.807 (a)(3), (b), and (c) of this chapter, and in addition the
 following requirements:

   (b) There must be a means to lock and safeguard each external door against
 opening in flight (either inadvertently by persons or as a result of
 mechanical failure or failure of a single structural element). Each external
 door must be operable from both the inside and the outside, even though
 persons may be crowded against the door on the inside of the airplane. Inward
 opening doors may be used if there are means to prevent occupants from
 crowding against the door to an extent that would interfere with the opening
 of the door. The means of opening must be simple and obvious and must be
 arranged and marked so that it can be readily located and operated, even in
 darkness. Auxiliary locking devices may be used.
   (c) Each external door must be reasonably free from jamming as a result of
 fuselage deformation in a minor crash.
   (d) Each external door must be located where persons using it will not be
 endangered by the propellers when appropriate operating procedures are used.
   (e) There must be a provision for direct visual inspection of the locking
 mechanism by crewmembers to determine whether external doors, for which the
 initial opening movement is outward (including passenger, crew, service, and
 cargo doors), are fully locked. In addition, there must be a visual means to
 signal to appropriate crewmembers when normally used external doors are
 closed and fully locked.
   (f) Cargo and service doors not suitable for use as exits in an emergency
 need only meet paragraph (e) of section 5(e) of this regulation and be
 safeguarded against opening in flight as a result of mechanical failure or
 failure of a single structural element.
   (g) The passenger entrance door must qualify as a floor level emergency
 exit. If an integral stair is installed at such a passenger entry door, the
 stair must be designed so that when subjected to the inertia forces specified
 in Sec. 23.561 of this chapter, and following the collapse of one or more
 legs of the landing gear, it will not interfere to an extent that will reduce
 the effectiveness of emergency egress through the passenger entry door. Each
 additional required emergency exit except floor level exits must be located
 over the wing or must be provided with acceptable means to assist the
 occupants in descending to the ground. In addition to the passenger entrance
 door--
   (1) For a total passenger seating capacity of 15 or less, an emergency
 exit, as defined in Sec. 23.807(b) of this chapter, is required on each side
 of the cabin; and
   (2) For a total passenger seating capacity of 16 through 19, three
 emergency exits, as defined in Sec. 23.807(b) of this chapter, are required
 with one on the same side as the door and two on the side opposite the door.
   (h) An evacuation demonstration must be conducted utilizing the maximum
 number of occupants for which certification is desired. It must be conducted
 under simulated night conditions utilizing only the emergency exits on the
 most critical side of the aircraft. The participants must be representative
 of average airline passengers with no prior practice or rehearsal for the
 demonstration. Evacuation must be completed within 90 seconds.
   (i) Each emergency exit must be marked with the word "Exit" by a sign which
 has white letters 1 inch high on a red background 2 inches high, be self-
 illuminated or independently internally electrically illuminated, and have a
 minimum luminescence (brightness) of at least 160 microlamberts. The colors
 may be reversed if the passenger compartment illumination is essentially the
 same.
   (j) Access to window type emergency exits may not be obstructed by seats or
 seat backs.
   (k) The width of the main passenger aisle at any point between seats must
 equal or exceed the values in the following table:

                                         Minimum main
                                       passenger aisle
                                           width--

                                       Less
                                     than 25
                        Number of     inches   25 inches

 56 FR 65638, No. 242, Dec. 17, 1991

   SUMMARY: This final rule amends the Federal Aviation Regulations (FAR) to
 adopt certain recommendations of the National Airspace Review (NAR)
 concerning changes to regulations and procedures in regard to airspace
 classifications. These changes are intended to: (1) Simplify airspace
 designations; (2) achieve international commonality of airspace designations;
 (3) increase standardization of equipment requirements for operations in
 various classifications of airspace; (4) describe appropriate pilot
 certificate requirements, visual flight rules (VFR) visibility and distance
 from cloud rules, and air traffic services offered in each class of airspace;
 and (5) satisfy the responsibilities of the United States as a member of the
 International Civil Aviation Organization (ICAO). The final rule also amends
 the requirement for minimum distance from clouds in certain airspace areas
 and the requirements for communications with air traffic control (ATC) in
 certain airspace areas; eliminates airport radar service areas (ARSAs),
 control zones, and terminal control areas (TCAs) as airspace classifications;
 and eliminates the term "airport traffic area." The FAA believes simplified
 airspace classifications will reduce existing airspace complexity and thereby
 enhance safety.

   EFFECTIVE DATE: These regulations become effective September 16, 1993,
 except that Secs. 11.61(c), 91.215(d), 71.601, 71.603, 71.605, 71.607, and

 amendatory instruction number 20, Sec. 71.1, is effective as of December 17,
 1991 through September 15, 1993, and that Secs. 71.11 and 71.19 become
 effective October 15, 1992. The incorporation by reference of FAA Order
 7400.7 in Sec. 71.1 (amendatory instruction number 20) is approved by the
 Director of the Federal Register as of December 17, 1991, through September
 15, 1993. The incorporation by reference of FAA Order 7400.9 in Sec. 71.1
 (amendatory instruction number 24) is approved by the Director of the

 SUMMARY: This action alters the Denver, CO, Class B Airspace Area to coincide
 with the scheduled opening date of the new Denver International Airport. The
 new Denver International Airport will replace the Denver Stapleton
 International Airport. This action will enable air traffic control (ATC) to
 provide terminal ATC service to turbojet aircraft in Class B airspace
 throughout transition to and from the en route structure. The lateral limits
 of the Class B airspace area will extend to 30 nautical miles from Denver
 International Airport to provide an area in which ATC can provide control
 services throughout critical maneuvering phases of flight operations in the
 terminal area. The upper limits of the Class B airspace area will increase to
 12,000 feet mean sea level (MSL). This action will enhance air traffic
 procedures and simplify visual flight rules (VFR) transient operations
 outside the Class B airspace area. An objective of this action is to increase
 safety substantially while accommodating the legitimate concerns of airspace
 users.

 EFFECTIVE DATE: 0701 UTC, December 19, 1993.

 SUMMARY: This final rule establishes a new Special Federal Aviation
 Regulation (SFAR) that will allow persons to bring a noise-restricted
 aircraft into the United States under certain conditions without requesting
 an exemption. The SFAR allows for the issuance of special flight
 authorizations for one-time flights of noise-restricted aircraft when they
 are entering the country to be noise retrofitted or sold for scrap. The SFAR
 is intended to reduce the paperwork burden on both applicants and the FAA, to
 reduce the processing time for routine actions, to implement certain
 provisions of the Airport Noise and Capacity Act of 1990, and to restore
 certain provisions of a similar SFAR that expired December 31, 1991.

 DATES: Effective June 3, 1993.

 57 FR 14472, No. 76, Apr. 20, 1992

 SUMMARY: This action complies with the Order of the President of the United
 States to prohibit the takeoff from, landing in, or overflight of the
 territory of the United States by an aircraft on a flight to or from the
 territory of Libya, other than takeoffs, landings, or overflights expressly
 approved by a United Nations (UN) special committee. This action also
 prohibits the landing in, takeoff from, or overflight of the territory of the
 United States by any aircraft on a flight from or to any intermediate
 destination, if the flight's origin or ultimate destination is Libya. This
 action is taken to prevent an undue hazard to the aircraft that would be
 engaged in such a flight, as well as to persons involved in the flight,
 arising from international adherence to or enforcement of UN Security Council
 Resolution 748 (1992) mandating, inter alia, an embargo of most air traffic
 with Libya. Issuance of this rule implements and is fully consistent with UN
 Security Council Resolution 748.

 DATES: Effective date: April 16, 1992. Expiration date: April 16, 1993.

 text is set forth as follows:

 Sec. 91.109  Flight instruction; Simulated instrument flight and certain
   flight tests.

   (a) No person may operate a civil aircraft (except a manned free balloon)
 that is being used for flight instruction unless that aircraft has fully
 functioning dual controls. However, instrument flight instruction may be
 given in a single-engine airplane equipped with a single, functioning
 throwover control wheel in place of fixed, dual controls of the elevator and
 ailerons when--
   (1) The instructor has determined that the flight can be conducted safely;
 and
   (2) The person manipulating the controls has at least a private pilot
 certificate with appropriate category and class ratings.
   (b) No person may operate a civil aircraft in simulated instrument flight
 unless--
   (1) The other control seat is occupied by a safety pilot who possesses at
 least a private pilot certificate with category and class ratings appropriate
 to the aircraft being flown.
   (2) The safety pilot has adequate vision forward and to each side of the
 aircraft, or a competent observer in the aircraft adequately supplements the
 vision of the safety pilot; and
   (3) Except in the case of lighter-than-air aircraft, that aircraft is
 equipped with fully functioning dual controls. However, simulated instrument
 flight may be conducted in a single-engine airplane, equipped with a single,
 functioning, throwover control wheel, in place of fixed, dual controls of the
 elevator and ailerons, when--
   (i) The safety pilot has determined that the flight can be conducted
 safely; and
   (ii) The person manipulating the controls has at least a private pilot
 certificate with appropriate category and class ratings.
   (c) No person may operate a civil aircraft that is being used for a flight
 test for an airline transport pilot certificate or a class or type rating on
 that certificate, or for a part 121 proficiency flight test, unless the pilot
 seated at the controls, other than the pilot being checked, is fully
 qualified to act as pilot in command of the aircraft.






 Sec. 91.111  Operating near other aircraft.

   (a) No person may operate an aircraft so close to another aircraft as to
 create a collision hazard.
   (b) No person may operate an aircraft in formation flight except by
 arrangement with the pilot in command of each aircraft in the formation.
   (c) No person may operate an aircraft, carrying passengers for hire, in
 formation flight.

   Effective Date Note: At 54 FR 34291, August 18, 1989, Sec. 91.111 was
 added effective August 18, 1990.






 Sec. 91.113  Right-of-way rules: Except water operations.

   (a) Inapplicability. This section does not apply to the operation of an
 aircraft on water.
   (b) General. When weather conditions permit, regardless of whether an
 operation is conducted under instrument flight rules or visual flight rules,
 vigilance shall be maintained by each person operating an aircraft so as to
 see and avoid other aircraft. When a rule of this section gives another
 aircraft the right-of-way, the pilot shall give way to that aircraft and may
 not pass over, under, or ahead of it unless well clear.
   (c) In distress. An aircraft in distress has the right-of-way over all
 other air traffic.
   (d) Converging. When aircraft of the same category are converging at
 approximately the same altitude (except head-on, or nearly so), the aircraft
 to the other's right has the right-of-way. If the aircraft are of different
 categories--
   (1) A balloon has the right-of-way over any other category of aircraft;
   (2) A glider has the right-of-way over an airship, airplane, or rotorcraft;
 and
   (3) An airship has the right-of-way over an airplane or rotorcraft.
   However, an aircraft towing or refueling other aircraft has the right-of-
 way over all other engine-driven aircraft.
   (e) Approaching head-on. When aircraft are approaching each other head-on,
 or nearly so, each pilot of each aircraft shall alter course to the right.
   (f) Overtaking. Each aircraft that is being overtaken has the right-of-way
 and each pilot of an overtaking aircraft shall alter course to the right to
 pass well clear.
   (g) Landing. Aircraft, while on final approach to land or while landing,
 have the right-of-way over other aircraft in flight or operating on the
 surface, except that they shall not take advantage of this rule to force an
 aircraft off the runway surface which has already landed and is attempting to
 make way for an aircraft on final approach. When two or more aircraft are
 approaching an airport for the purpose of landing, the aircraft at the lower
 altitude has the right-of-way, but it shall not take advantage of this rule
 to cut in front of another which is on final approach to land or to overtake
 that aircraft.

   Effective Date Note: At 54 FR 34291, August 18, 1989, Sec. 91.113 was
 added effective August 18, 1990.






 Sec. 91.115   ATC clearance and flight plan required.

   No person may operate an aircraft in controlled airspace under IFR unless--
   (a) He has filed an IFR flight plan; and
   (b) He has received an appropriate ATC clearance.

   Effective Date Note: At 54 FR 34291, August 18, 1989, Sec. 91.115 was
 replaced effective August 18, 1990. For the convenience of the user, the new
 text is set forth as follows:

 Sec. 91.115  Right-of-way rules: Water operations.

   (a) General. Each person operating an aircraft on the water shall, insofar
 as possible, keep clear of all vessels and avoid impeding their navigation,
 and shall give way to any vessel or other aircraft that is given the right-
 of-way by any rule of this section.
   (b) Crossing. When aircraft, or an aircraft and a vessel, are on crossing
 courses, the aircraft or vessel to the other's right has the right-of-way.
   (c) Approaching head-on. When aircraft, or an aircraft and a vessel, are
 approaching head-on, or nearly so, each shall alter its course to the right
 to keep well clear.
   (d) Overtaking. Each aircraft or vessel that is being overtaken has the
 right-of-way, and the one overtaking shall alter course to keep well clear.
   (e) Special circumstances. When aircraft, or an aircraft and a vessel,
 approach so as to involve risk of collision, each aircraft or vessel shall
 proceed with careful regard to existing circumstances, including the
 limitations of the respective craft.






 Sec. 91.117  Aircraft speed.

   (a) Unless otherwise authorized by the Administrator, no person may operate
 an aircraft below 10,000 feet MSL at an indicated airspeed of more than 250
 knots (288 m.p.h.).
   (b) Unless otherwise authorized or required by ATC, no person may operate
 an aircraft within an airport traffic area at an indicated airspeed of more
 than 200 knots (230 m.p.h.). This paragraph (b) does not apply to any
 operations within a terminal control area. Such operations shall comply with
 paragraph (a) of this section.
   (c) No person may operate an aircraft in the airspace underlying a terminal
 control area, or in a VFR corridor designated through a terminal control
 area, at an indicated airspeed of more than 200 knots (230 m.p.h.).
   (d) If the minimum safe airspeed for any particular operation is greater
 than the maximum speed prescribed in this section, the aircraft may be
 operated at that minimum speed.

 58 FR 43553, No. 157, Aug. 17, 1993

   SUMMARY: This action corrects the Airspace Reclassification Final Rule
 effective September 16, 1993. The Airspace Reclassification Rule
 inadvertently assigned the authority to air traffic controllers to allow
 aircraft operators to deviate from the maximum airspeed restriction below
 10,000 feet. The authority to approve deviation from the speed limits
 contained in the Federal Aviation Regulations (FAR) rests with the
 Administrator, and the FAA did not intend to amend the approving authority.
 This action reestablishes the Administrator as the proper authority to permit
 waivers of aircraft speed. This action also corrects the inadvertent
 inclusion of Class B airspace in the maximum airspeed restriction effected by
 the Airspace Reclassification Final Rule.

   EFFECTIVE DATE: This correcting amendment is effective as of September 16,
 1993.

 Sec. 91.119   Minimum altitudes for IFR operations.

   (a) Except when necessary for takeoff or landing, or unless otherwise
 authorized by the Administrator, no person may operate an aircraft under IFR
 below--
   (1) The applicable minimum altitudes prescribed in Parts 95 and 97 of this
 chapter; or
   (2) If no applicable minimum altitude is prescribed in those parts--
   (i) In the case of operations over an area designated as a mountainous area
 in Part 95 an altitude of 2,000 feet above the highest obstacle within a
 horizontal distance of five statute miles from the course to be flown; or
   (ii) In any other case, an altitude of 1,000 feet above the highest
 obstacle within a horizontal distance of five statute miles from the course
 to be flown.

 However, if both a MEA and a MOCA are prescribed for a particular route or
 route segment, a person may operate an aircraft below the MEA down to, but
 not below, the MOCA, when within 25 statute miles of the VOR concerned (based
 on the pilot's reasonable estimate of that distance).
   (b) Climb. Climb to a higher minimum IFR altitude shall begin immediately
 after passing the point beyond which that minimum altitude applies, except
 that, when ground obstructions intervene, the point beyond which the higher
 minimum altitude applies shall be crossed at or above the applicable MCA.

   Effective Date Note: At 54 FR 34291, August 18, 1989, Sec. 91.119 was
 replaced effective August 18, 1990. For the convenience of the user, the new
 text is set forth as follows:

 Sec. 91.119  Minimum safe altitudes: General.

   Except when necessary for takeoff or landing, no person may operate an
 aircraft below the following altitudes:
   (a) Anywhere. An altitude allowing, if a power unit fails, an emergency
 landing without undue hazard to persons or property on the surface.
   (b) Over congested areas. Over any congested area of a city, town, or
 settlement, or over any open air assembly of persons, an altitude of 1,000
 feet above the highest obstacle within a horizontal radius of 2,000 feet of
 the aircraft.
   (c) Over other than congested areas. An altitude of 500 feet above the
 surface, except over open water or sparsely populated areas. In those cases,
 the aircraft may not be operated closer than 500 feet to any person, vessel,
 vehicle, or structure.
   (d) Helicopters. Helicopters may be operated at less than the minimums
 prescribed in paragraph (b) or (c) of this section if the operation is
 conducted without hazard to persons or property on the surface. In addition,
 each person operating a helicopter shall comply with any routes or altitudes
 specifically prescribed for helicopters by the Administrator.






 Sec. 91.121   IFR cruising altitude or flight level.

   (a) In controlled airspace. Each person operating an aircraft under IFR in
 level cruising flight in controlled airspace shall maintain the altitude or
 flight level assigned that aircraft by ATC. However, if the ATC clearance
 assigns "VFR conditions on-top," he shall maintain an altitude or flight
 level as prescribed by Sec. 91.109.
   (b) In uncontrolled airspace. Except while holding in a holding pattern of
 two minutes or less, or while turning, each person operating an aircraft
 under IFR in level cruising flight, in uncontrolled airspace, shall maintain
 an appropriate altitude as follows:
   (1) When operating below 18,000 feet MSL and--
   (i) On a magnetic course of zero degrees through 179 degrees, any odd
 thousand foot MSL altitude (such as 3,000, 5,000, or 7,000); or
   (ii) On a magnetic course of 180 degrees through 359 degrees, any even
 thousand foot MSL altitude (such as 2,000, 4,000, or 6,000).
   (2) When operating at or above 18,000 feet MSL but below flight level 290,
 and--
   (i) On a magnetic course of zero degrees through 179 degrees, any odd
 flight level (such as 190, 210, or 230); or
   (ii) On a magnetic course of 180 degrees through 359 degrees, any even
 flight level (such as 180, 200, or 220).
   (3) When operating at flight level 290 and above, and--
   (i) On a magnetic course of zero degrees through 179 degrees, any flight
 level, at 4,000 foot intervals, beginning at and including flight level 290
 (such as flight level 290, 330, or 370); or
   (ii) On a magnetic course of 180 degrees through 359 degrees, any flight
 level, at 4,000 foot intervals, beginning at and including flight level 310
 (such as flight level 310, 350, or 390).

 text is set forth as follows:

 Sec. 91.121  Altimeter settings.

   (a) Each person operating an aircraft shall maintain the cruising altitude
 or flight level of that aircraft, as the case may be, by reference to an
 altimeter that is set, when operating--
   (1) Below 18,000 feet MSL, to--
   (i) The current reported altimeter setting of a station along the route and
 within 100 nautical miles of the aircraft;
   (ii) If there is no station within the area prescribed in paragraph
 (a)(1)(i) of this section, the current reported altimeter setting of an
 appropriate available station; or
   (iii) In the case of an aircraft not equipped with a radio, the elevation
 of the departure airport or an appropriate altimeter setting available before
 departure; or
   (2) At or above 18,000 feet MSL, to 29.92'' Hg.
   (b) The lowest usable flight level is determined by the atmospheric
 pressure in the area of operation as shown in the following table:

                                               Lowest

                          27.41 through 26.92     210

   (c) To convert minimum altitude prescribed under Secs. 91.119 and 91.177 to
 the minimum flight level, the pilot shall take the flight level equivalent of
 the minimum altitude in feet and add the appropriate number of feet specified
 below, according to the current reported altimeter setting:

 Sec. 91.123  Compliance with ATC clearances and instructions.

   (a) When an ATC clearance has been obtained, no pilot in command may
 deviate from that clearance, except in an emergency, unless an amended
 clearance is obtained. A pilot in command may cancel an IFR flight plan if
 that pilot is operating in VFR weather conditions outside of positive
 controlled airspace. If a pilot is uncertain of the meaning of an ATC
 clearance, the pilot shall immediately request clarification from ATC.
   (b) Except in an emergency, no person may operate an aircraft contrary to
 an ATC instruction in an area in which air traffic control is exercised.
   (c) Each pilot in command who, in an emergency, deviates from an ATC
 clearance or instruction shall notify ATC of that deviation as soon as
 possible.
   (d) Each pilot in command who (though not deviating from a rule of this
 subpart) is given priority by ATC in an emergency, shall submit a detailed
 report of that emergency within 48 hours to the manager of that ATC facility,
 if requested by ATC.
   (e) Unless otherwise authorized by ATC, no person operating an aircraft may
 operate that aircraft according to any clearance or instruction that has been
 issued to the pilot of another aircraft for radar air traffic control
 purposes.

   Effective Date Note: Amdt. No. 91-227, 56 FR 65658, Dec. 17, 1991, revised
 paragraph (a) of this section effective September 16, 1993 to read as
 follows:

   (a) When an ATC clearance has been obtained, a pilot in command may not
 deviate from that clearance, except in an emergency, unless that pilot
 obtains an amended clearance. However, except in Class A airspace, this
 paragraph does not prohibit that pilot from canceling an IFR flight plan if

 56 FR 65638, No. 242, Dec. 17, 1991

   SUMMARY: This final rule amends the Federal Aviation Regulations (FAR) to
 adopt certain recommendations of the National Airspace Review (NAR)
 concerning changes to regulations and procedures in regard to airspace
 classifications. These changes are intended to: (1) Simplify airspace
 designations; (2) achieve international commonality of airspace designations;
 (3) increase standardization of equipment requirements for operations in
 various classifications of airspace; (4) describe appropriate pilot
 certificate requirements, visual flight rules (VFR) visibility and distance
 from cloud rules, and air traffic services offered in each class of airspace;
 and (5) satisfy the responsibilities of the United States as a member of the
 International Civil Aviation Organization (ICAO). The final rule also amends
 the requirement for minimum distance from clouds in certain airspace areas
 and the requirements for communications with air traffic control (ATC) in
 certain airspace areas; eliminates airport radar service areas (ARSAs),
 control zones, and terminal control areas (TCAs) as airspace classifications;
 and eliminates the term "airport traffic area." The FAA believes simplified
 airspace classifications will reduce existing airspace complexity and thereby
 enhance safety.

   EFFECTIVE DATE: These regulations become effective September 16, 1993,
 except that Secs. 11.61(c), 91.215(d), 71.601, 71.603, 71.605, 71.607, and
 71.609 and Part 75 become effective December 12, 1991, and except that
 amendatory instruction number 20, Sec. 71.1 is effective as of September 15,
 1993, and that Secs. 71.11 and 71.19 become effective October 15, 1992. The
 incorporation by reference of FAA Order 7400.7 in Sec. 71.1 (amendatory
 instruction number 20) is approved by the Director of the Federal Register
 as of December 17, 1991, through September 15, 1993. The incorporation by
 reference of FAA Order 7400.9 in Sec. 71.1 (amendatory instruction number 24)
 is approved by the Director of the Federal Register as of September 16,
 1993 through September 15, 1994.

 Sec. 91.125   IFR radio communications.

   The pilot in command of each aircraft operated under IFR in controlled
 airspace shall have a continuous watch maintained on the appropriate
 frequency and shall report by radio as soon as possible--
   (a) The time and altitude of passing each designated reporting point, or
 the reporting points specified by ATC, except that while the aircraft is
 under radar control, only the passing of those reporting points specifically
 requested by ATC need be reported;

 Sec. 91.126  Operating on or in the vicinity of an airport in Class G
     airspace.

   (a) General. Unless otherwise authorized or required, each person operating
 an aircraft on or in the vicinity of an airport in a Class G airspace area
 must comply with the requirements of this section.
   (b) Direction of turns. When approaching to land at an airport without an
 operating control tower in Class G airspace--
   (1) Each pilot of an airplane must make all turns of that airplane to the
 left unless the airport displays approved light signals or visual markings
 indicating that turns should be made to the right, in which case the pilot
 must make all turns to the right; and
   (2) Each pilot of a helicopter must avoid the flow of fixed-wing aircraft.
   (c) Flap settings. Except when necessary for training or certification, the
 pilot in command of a civil turbojet-powered aircraft must use, as a final
 flap setting, the minimum certificated landing flap setting set forth in the
 approved performance information in the Airplane Flight Manual for the
 applicable conditions. However, each pilot in command has the final authority
 and responsibility for the safe operation of the pilot's airplane, and may
 use a different flap setting for that airplane if the pilot determines that
 it is necessary in the interest of safety.
   (d) Communications with control towers. Unless otherwise authorized or
 required by ATC, no person may operate an aircraft to, from, through, or on
 an airport having an operational control tower unless two-way radio

 Sec. 91.129  Operations in Class D airspace.

   (a) General. Unless otherwise authorized or required by the ATC facility
 having jurisdiction over the Class D airspace area, each person operating an
 aircraft in Class D airspace must comply with the applicable provisions of
 this section. In addition, each person must comply with Secs. 91.126 and
 91.127. For the purpose of this section, the primary airport is the airport
 for which the Class D airspace area is designated. A satellite airport is any
 other airport within the Class D airspace area.
   (b) Deviations. An operator may deviate from any provision of this section
 under the provisions of an ATC authorization issued by the ATC facility
 having jurisdiction over the airspace concerned. ATC may authorize a
 deviation on a continuing basis or for an individual flight, as appropriate.
   (c) Communications. Each person operating an aircraft in Class D airspace
 must meet the following two-way radio communications requirements:
   (1) Arrival or through flight. Each person must establish two-way radio
 communications with the ATC facility (including foreign ATC in the case of
 foreign airspace designated in the United States) providing air traffic
 services prior to entering that airspace and thereafter maintain those
 communications while within that airspace.
   (2) Departing flight. Each person--
   (i) From the primary airport or satellite airport with an operating control
 tower must establish and maintain two-way radio communications with the
 control tower, and thereafter as instructed by ATC while operating in the
 Class D airspace area; or
   (ii) From a satellite airport without an operating control tower, must
 establish and maintain two-way radio communications with the ATC facility
 having jurisdiction over the Class D airspace area as soon as practicable
 after departing.
   (d) Communications failure. Each person who operates an aircraft in a Class
 D airspace area must maintain two-way radio communications with the ATC
 facility having jurisdiction over that area.
   (1) If the aircraft radio fails in flight under IFR, the pilot must comply
 with Sec. 91.185 of the part.
   (2) If the aircraft radio fails in flight under VFR, the pilot in command
 may operate that aircraft and land if--
   (i) Weather conditions are at or above basic VFR weather minimums;
   (ii) Visual contact with the tower is maintained; and
   (iii) A clearance to land is received.
   (e) Minimum Altitudes. When operating to an airport in Class D airspace,
 each pilot of--
   (1) A large or turbine-powered airplane shall, unless otherwise required
 by the applicable distance from cloud criteria, enter the traffic pattern at
 an altitude of at least 1,500 feet above the elevation of the airport and
 maintain at least 1,500 feet until further descent is required for a safe
 landing;
   (2) A large or turbine-powered airplane approaching to land on a runway
 served by an instrument landing system (ILS), if the airplane is ILS
 equipped, shall fly that airplane at an altitude at or above the glide slope
 between the outer marker (or point of interception of glide slope, if
 compliance with the applicable distance from clouds criteria requires
 interception closer in) and the middle marker; and
   (3) An airplane approaching to land on a runway served by a visual
 approach slope indicator shall maintain an altitude at or above the glide
 slope until a lower altitude is necessary for safe landing.

 Paragraphs (e)(2) and (e)(3) of this section do not prohibit normal
 bracketing maneuvers above or below the glide slope that are conducted for
 the purpose of remaining on the glide slope.
   (f) Approaches. Except when conducting a circling approach under Part 97 of
 this chapter or unless otherwise required by ATC, each pilot must--
   (1) Circle the airport to the left, if operating an airplane; or
   (2) Avoid the flow of fixed-wing aircraft, if operating a helicopter.
   (g) Departures. No person may operate an aircraft departing from an airport
 except in compliance with the following:
   (1) Each pilot must comply with any departure procedures established for
 that airport by the FAA.
   (2) Unless otherwise required by the prescribed departure procedure for
 that airport or the applicable distance from clouds criteria, each pilot of a
 turbine-powered airplane and each pilot of a large airplane must climb to an
 altitude of 1,500 feet above the surface as rapidly as practicable.
   (h) Noise abatement. Where a formal runway use program has been established
 by the FAA, each pilot of a large or turbine-powered airplane assigned a
 noise abatement runway by ATC must use that runway. However, consistent with
 the final authority of the pilot in command concerning the safe operation of
 the aircraft as prescribed in Sec. 91.3(a), ATC may assign a different runway
 if requested by the pilot in the interest of safety.
   (i) Takeoff, landing, taxi clearance. No person may, at any airport with an
 operating control tower, operate an aircraft on a runway or taxiway, or take
 off or land an aircraft, unless an appropriate clearance is received from
 ATC. A clearance to "taxi to" the takeoff runway assigned to the aircraft is
 not a clearance to cross that assigned takeoff runway, or to taxi on that
 runway at any point, but is a clearance to cross other runways that intersect
 the taxi route to that assigned takeoff runway. A clearance to "taxi to" any
 point other than an assigned takeoff runway is clearance to cross all runways
 that intersect the taxi route to that point.

 56 FR 65638, No. 242, Dec. 17, 1991

   SUMMARY: This final rule amends the Federal Aviation Regulations (FAR) to
 adopt certain recommendations of the National Airspace Review (NAR)
 concerning changes to regulations and procedures in regard to airspace
 classifications. These changes are intended to: (1) Simplify airspace
 designations; (2) achieve international commonality of airspace designations;
 (3) increase standardization of equipment requirements for operations in
 various classifications of airspace; (4) describe appropriate pilot
 certificate requirements, visual flight rules (VFR) visibility and distance
 from cloud rules, and air traffic services offered in each class of airspace;
 and (5) satisfy the responsibilities of the United States as a member of the
 International Civil Aviation Organization (ICAO). The final rule also amends
 the requirement for minimum distance from clouds in certain airspace areas
 and the requirements for communications with air traffic control (ATC) in
 certain airspace areas; eliminates airport radar service areas (ARSAs),
 control zones, and terminal control areas (TCAs) as airspace classifications;
 and eliminates the term "airport traffic area." The FAA believes simplified
 airspace classifications will reduce existing airspace complexity and thereby
 enhance safety.

   EFFECTIVE DATE: These regulations become effective September 16, 1993,

 concerning changes to regulations and procedures in regard to airspace
 classifications. These changes are intended to: (1) Simplify airspace
 designations; (2) achieve international commonality of airspace designations;
 (3) increase standardization of equipment requirements for operations in
 various classifications of airspace; (4) describe appropriate pilot
 certificate requirements, visual flight rules (VFR) visibility and distance
 from cloud rules, and air traffic services offered in each class of airspace;
 and (5) satisfy the responsibilities of the United States as a member of the
 International Civil Aviation Organization (ICAO). The final rule also amends
 the requirement for minimum distance from clouds in certain airspace areas
 and the requirements for communications with air traffic control (ATC) in
 certain airspace areas; eliminates airport radar service areas (ARSAs),
 control zones, and terminal control areas (TCAs) as airspace classifications;
 and eliminates the term "airport traffic area." The FAA believes simplified
 airspace classifications will reduce existing airspace complexity and thereby
 enhance safety.

   EFFECTIVE DATE: These regulations become effective September 16, 1993,
 except that Secs. 11.61(c), 91.215(d), 71.601, 71.603, 71.605, 71.607, and
 71.609 and Part 75 become effective December 12, 1991, and except that
 amendatory instruction number 20, Sec. 71.1 is effective as of September 15,
 1993, and that Secs. 71.11 and 71.19 become effective October 15, 1992. The
 incorporation by reference of FAA Order 7400.7 in Sec. 71.1 (amendatory
 instruction number 20) is approved by the Director of the Federal Register
 as of December 17, 1991, through September 15, 1993. The incorporation by
 reference of FAA Order 7400.9 in Sec. 71.1 (amendatory instruction number 24)
 is approved by the Director of the Federal Register as of September 16,
 1993 through September 15, 1994.

 SUMMARy: This action amends certain regulations governing special visual
 flight rules (SVFR) operations. By omission of certain words and phrases, the
 Airspace Reclassification Final Rule inadvertently altered the applicability
 and scope of the part 91 SVFR provisions. Further, some airspace revisions in
 the Terminal Airspace Reconfiguration final rule resulted in an unintentional
 reduction of the amount of airspace within which SVFR operations could be
 conducted at some airports. This action restores the applicability and scope

   (b) Special VFR operations may only be conducted--
   (1) With an ATC clearance;
   (2) Clear of clouds;
   (3) Except for helicopters, when flight visibility is at least 1 statute
 mile; and
   (4) Except for helicopters, between sunrise and sunset (or in Alaska, when
 the sun is 6 deg. or more above the horizon) unless--
   (i) The person being granted the ATC clearance meets the applicable
 requirements for instrument flight under part 61 of this chapter; and
   (ii) The aircraft is equipped as required in Sec. 91.205(d).
   (c) No person may take off or land an aircraft (other than a helicopter)
 under special VFR--
   (1) Unless ground visibility is at least 1 statute mile; or
   (2) If ground visibility is not reported, unless flight visibility is at
 least 1 statute mile.

   (1) An aircraft that carries a special flight permit, a current
 experimental certificate, or a provisional airworthiness certificate;
   (2) An aircraft inspected in accordance with an approved aircraft
 inspection program under Part 123, 125, or 135 of this chapter and so
 identified by the registration number in the operations specifications of the
 certificate holder having the approved inspection program; or
   (3) An aircraft subject to the requirements of paragraph (d) or (e) of this
 section.
   (d) Progressive inspection. Each registered owner or operator of an
 aircraft desiring to use a progressive inspection program must submit a
 written request to the FAA Flight Standards district office having
 jurisdiction over the area in which the applicant is located, and shall
 provide--
   (1) A certificated mechanic holding an inspection authorization, a
 certificated airframe repair station, or the manufacturer of the aircraft to
 supervise or conduct the progressive inspection;
   (2) A current inspection procedures manual available and readily
 understandable to pilot and maintenance personnel containing, in detail--
   (i) An explanation of the progressive inspection, including the continuity
 of inspection responsibility, the making of reports, and the keeping of
 records and technical reference material;
   (ii) An inspection schedule, specifying the intervals in hours or days when
 routine and detailed inspections will be performed and including instructions
 for exceeding an inspection interval by not more than 10 hours while en route
 and for changing an inspection interval because of service experience;
   (iii) Sample routine and detailed inspection forms and instructions for
 their use; and
   (iv) Sample reports and records and instructions for their use;
   (3) Enough housing and equipment for necessary disassembly and proper
 inspection of the aircraft; and

 The frequency and detail of the progressive inspection shall provide for the
 complete inspection of the aircraft within each 12-calendar months and be
 consistent with the manufacturer's recommendations, field service experience,
 and the kind of operation in which the aircraft is engaged. The progressive
 inspection schedule must ensure that the aircraft, at all times, will be
 airworthy and will conform to all applicable FAA aircraft specifications,
 type certificate data sheets, airworthiness directives, and other approved
 data. If the progressive inspection is discontinued, the owner or operator
 shall immediately notify the local FAA Flight Standards district office, in
 writing, of the discontinuance. After the discontinuance, the first annual
 inspection under Sec. 91.169(a) is due within 12-calendar months after the
 last complete inspection of the aircraft under the progressive inspection.
 The 100-hour inspection under Sec. 91.169(b) is due within 100 hours after
 that complete inspection. A complete inspection of the aircraft, for the
 purpose of determining when the annual and 100-hour inspections are due,
 requires a detailed inspection of the aircraft and all its components in
 accordance with the progressive inspection. A routine inspection of the
 aircraft and a detailed inspection of several components is not considered to
 be a complete inspection.
   (e) Large airplanes (to which Part 125 is not applicable), turbojet
 multiengine airplanes, and turbopropeller-powered multiengine airplanes. No
 person may operate a large airplane, turbojet multiengine airplane, or
 turbopropeller-powered multiengine airplane unless the replacement times for
 life-limited parts specified in the aircraft specifications, type data
 sheets, or other documents approved by the Administrator are complied with
 and the airplane, including the airframe, engines, propellers, appliances,
 survival equipment, and emergency equipment, is inspected in accordance with
 an inspection program selected under the provisions of paragraph (f) of this
 section.
   (f) Selection of inspection programs under paragraph (e) of this section.
 The registered owner or operator of each airplane described in paragraph (e)
 of this section must select, identify in the aircraft maintenance records,
 and use one of the following programs for the inspection of that airplane:
   (1) A continuous airworthiness inspection program that is part of a
 continuous airworthiness maintenance program currently in use by a person
 holding an air carrier operating certificate or an operating certificate
 issued under Part 121, 127, or 135 of this chapter and operating that make
 and model airplane under Part 121 or 127 or operating that make and model
 under Part 135 and maintaining it under Sec. 135.411(a)(2).
   (2) An approved aircraft inspection program approved under Sec. 135.419 of

 certificate issued under Part 135.
   (3) An approved continuous inspection program currently in use by a person
 certificated under Part 123 of this chapter.
   (4) A current inspection program recommended by the manufacturer.
   (5) Any other inspection program established by the registered owner or
 operator of that airplane and approved by the Administrator under paragraph
 (g) of this section. However, the Administrator may require revision to this
 inspection program in accordance with the provisions of Sec. 91.170.

 Each operator shall include in the selected program the name and address of
 the person responsible for scheduling the inspections required by the program
 and make a copy of that program available to the person performing
 inspections on the airplane and, upon request, to the Administrator.
   (g) Inspection program approval under paragraph (e) of this section. Each
 operator of an airplane desiring to establish or change an approved
 inspection program under paragraph (f)(5) of this section must submit the
 program for approval to the local FAA Flight Standards district office having
 jurisdiction over the area in which the airplane is based. The program must
 be in writing and include at least the following information:
   (1) Instruction and procedures for the conduct of inspections for the
 particular make and model airplane, including necessary tests and checks. The
 instructions and procedures must set forth in detail the parts and areas of
 the airframe, engines, propellers, and appliances, including survival and
 emergency equipment required to be inspected.
   (2) A schedule for performing the inspections that must be performed under
 the program expressed in terms of the time in service, calendar time, number
 of system operations, or any combination of these.
   (h) Changes from one inspection program to another. When an operator
 changes from one inspection program under paragraph (f) of this section to
 another, the time in service, calendar times, or cycles of operation
 accumulated under the previous program must be applied in determining
 inspection due times under the new program.

 Sec. 91.175  Takeoff and landing under IFR.

   (a) Instrument approaches to civil airports.
   Unless otherwise authorized by the Administrator, when an instrument
 letdown to a civil airport is necessary, each person operating an aircraft,
 except a military aircraft of the United States, shall use a standard
 instrument approach procedure prescribed for the airport in part 97 of this
 chapter.
   (b) Authorized DH or MDA. For the purpose of this section, when the
 approach procedure being used provides for and requires the use of a DH or
 MDA, the authorized DH or MDA is the highest of the following:
   (1) The DH or MDA prescribed by the approach procedure.
   (2) The DH or MDA prescribed for the pilot in command.
   (3) The DH or MDA for which the aircraft is equipped.
   (c) Operation below DH or MDA. Where a DH or MDA is applicable, no pilot
 may operate an aircraft, except a military aircraft of the United States, at
 any airport below the authorized MDA or continue an approach below the
 authorized DH unless--
   (1) The aircraft is continuously in a position from which a descent to a
 landing on the intended runway can be made at a normal rate of descent using
 normal maneuvers, and for operations conducted under part 121 or part 135
 unless that descent rate will allow touchdown to occur within the touchdown
 zone of the runway of intended landing;
   (2) The flight visibility is not less than the visibility prescribed in the
 standard instrument approach being used; and
   (3) Except for a Category II or Category III approach where any necessary
 visual reference requirements are specified by the Administrator, at least
 one of the following visual references for the intended runway is distinctly
 visible and identifiable to the pilot:
   (i) The approach light system, except that the pilot may not descend below
 100 feet above the touchdown zone elevation using the approach lights as a
 reference unless the red terminating bars or the red side row bars are also
 distinctly visible and identifiable.
   (ii) The threshold.
   (iii) The threshold markings.
   (iv) The threshold lights.
   (v) The runway end identifier lights.
   (vi) The visual approach slope indicator.
   (vii) The touchdown zone or touchdown zone markings.
   (viii) The touchdown zone lights.
   (ix) The runway or runway markings.
   (x) The runway lights.
   (d) Landing. No pilot operating an aircraft, except a military aircraft of
 the United States, may land that aircraft when the flight visibility is less
 than the visibility prescribed in the standard instrument approach procedure
 being used.
   (e) Missed approach procedures. Each pilot operating an aircraft, except a
 military aircraft of the United States, shall immediately execute an
 appropriate missed approach procedure when either of the following conditions
 exist:
   (1) Whenever the requirements of paragraph (c) of this section are not met
 at either of the following times:
   (i) When the aircraft is being operated below MDA; or
   (ii) Upon arrival at the missed approach point, including a DH where a DH
 is specified and its use is required, and at any time after that until
 touchdown.
   (2) Whenever an identifiable part of the airport is not distinctly visible
 to the pilot during a circling maneuver at or above MDA, unless the inability
 to see an identifiable part of the airport results only from a normal bank of
 the aircraft during the circling approach.
   (f) Civil airport takeoff minimums. Unless otherwise authorized by the
 Administrator, no pilot operating an aircraft under parts 121, 125, 127, 129,
 or 135 of this chapter may take off from a civil airport under IFR unless
 weather conditions are at or above the weather minimum for IFR takeoff
 prescribed for that airport under part 97 of this chapter. If takeoff
 minimums are not prescribed under part 97 of this chapter for a particular
 airport, the following minimums apply to takeoffs under IFR for aircraft
 operating under those parts:
   (1) For aircraft, other than helicopters, having two engines or less--1
 statute mile visibility.
   (2) For aircraft having more than two engines-- 1/2  statute mile
 visibility.
   (3) For helicopters--1/2 statute mile visibility.
   (g) Military airports. Unless otherwise prescribed by the Administrator,
 each person operating a civil aircraft under IFR into or out of a military
 airport shall comply with the instrument approach procedures and the takeoff
 and landing minimum prescribed by the military authority having jurisdiction
 of that airport.
   (h) Comparable values of RVR and ground visibility. (1) Except for Category
 II or Category III minimums, if RVR minimums for takeoff or landing are
 prescribed in an instrument approach procedure, but RVR is not reported for
 the runway of intended operation, the RVR minimum shall be converted to
 ground visibility in accordance with the table in paragraph (h)(2) of this
 section and shall be the visibility minimum for takeoff or landing on that
 runway.

                                                          Visibility
                                                           (statute

   (i) Operations on unpublished routes and use of radar in instrument
 approach procedures. When radar is approved at certain locations for ATC
 purposes, it may be used not only for surveillance and precision radar
 approaches, as applicable, but also may be used in conjunction with
 instrument approach procedures predicated on other types of radio
 navigational aids. Radar vectors may be authorized to provide course guidance
 through the segments of an approach to the final course or fix. When
 operating on an unpublished route or while being radar vectored, the pilot,
 when an approach clearance is received, shall, in addition to complying with
 Sec. 91.177, maintain the last altitude assigned to that pilot until the
 aircraft is established on a segment of a published route or instrument
 approach procedure unless a different altitude is assigned by ATC. After the
 aircraft is so established, published altitudes apply to descent within each
 succeeding route or approach segment unless a different altitude is assigned
 by ATC. Upon reaching the final approach course or fix, the pilot may either
 complete the instrument approach in accordance with a procedure approved for
 the facility or continue a surveillance or precision radar approach to a
 landing.
   (j) Limitation on procedure turns. In the case of a radar vector to a final
 approach course or fix, a timed approach from a holding fix, or an approach
 for which the procedure specifies "No PT," no pilot may make a procedure turn
 unless cleared to do so by ATC.
   (k) ILS components. The basic ground components of an ILS are the
 localizer, glide slope, outer marker, middle marker, and, when installed for
 use with Category II or Category III instrument approach procedures, an inner
 marker. A compass locator or precision radar may be substituted for the outer
 or middle marker. DME, VOR, or nondirectional beacon fixes authorized in the
 standard instrument approach procedure or surveillance radar may be
 substituted for the outer marker. Applicability of, and substitution for, the
 inner marker for Category II or III approaches is determined by the
 appropriate part 97 approach procedure, letter of authorization, or
 operations specification pertinent to the operations.






 Sec. 91.177  Minimum altitudes for IFR operations.

   (a) Operation of aircraft at minimum altitudes. Except when necessary for
 takeoff or landing, no person may operate an aircraft under IFR below--

   (1) The applicable minimum altitudes prescribed in Parts 95 and 97 of this
 chapter; or
   (2) If no applicable minimum altitude is prescribed in those parts--
   (i) In the case of operations over an area designated as a mountainous area
 in part 95, an altitude of 2,000 feet above the highest obstacle within a
 horizontal distance of 4 nautical miles from the course to be flown; or
   (ii) In any other case, an altitude of 1,000 feet above the highest
 obstacle within a horizontal distance of 4 nautical miles from the course to
 be flown.

 However, if both a MEA and a MOCA are prescribed for a particular route or
 route segment, a person may operate an aircraft below the MEA down to, but
 not below, the MOCA, when within 22 nautical miles of the VOR concerned

 57 FR 34614, No. 151, Aug. 5, 1992

 SUMMARY: The FAA is rescinding the Mode S transponder requirement for
 aircraft operating under part 91 of the Federal Aviation Regulations. The
 Mode S ground sensors, the bulwark of the Model S system, are not expected to
 be fully operational until late 1995. Therefore, requiring all aircraft to
 have Mode S transponders at this time is not essential for a safe and
 efficient National Airspace System. Until the installation of the Mode S
 ground sensors and studies of their effectiveness are completed, the FAA has
 determined that it is not in the public interest to require that any
 transponder newly installed in a general aviation aircraft after July 1,
 1992, be a Mode S transponder.

 EFFECTIVE DATE: July 30, 1992.

 Sec. 91.217  Data correspondence between automatically reported pressur
   altitude data and the pilot's altitude reference.

   No person may operate any automatic pressure altitude reporting equipment
 associated with a radar beacon transponder--
   (a) When deactivation of that equipment is directed by ATC;
   (b) Unless, as installed, that equipment was tested and calibrated to
 transmit altitude data corresponding within 125 feet (on a 95 percent
 probability basis) of the indicated or calibrated datum of the altimeter
 normally used to maintain flight altitude, with that altimeter referenced to
 29.92 inches of mercury for altitudes from sea level to the maximum operating
 altitude of the aircraft; or
   (c) Unless the altimeters and digitizers in that equipment meet the
 standards of TSO-C10b and TSO-C88, respectively.

   Effective Date Note: At 54 FR 34291, August 18, 1989, Sec. 91.217 was
 added effective August 18, 1990.






 Sec. 91.219  Altitude alerting system or device: Turbojet-powered civil
   airplanes.

   (a) Except as provided in paragraph (d) of this section, no person may
 operate a turbojet-powered U.S.-registered civil airplane unless that
 airplane is equipped with an approved altitude alerting system or device that
 is in operable condition and meets the requirements of paragraph (b) of this
 section.
   (b) Each altitude alerting system or device required by paragraph (a) of
 this section must be able to--
   (1) Alert the pilot--
   (i) Upon approaching a preselected altitude in either ascent or descent, by
 a sequence of both aural and visual signals in sufficient time to establish
 level flight at that preselected altitude; or
   (ii) Upon approaching a preselected altitude in either ascent or descent,
 by a sequence of visual signals in sufficient time to establish level flight
 at that preselected altitude, and when deviating above and below that
 preselected altitude, by an aural signal;
   (2) Provide the required signals from sea level to the highest operating
 altitude approved for the airplane in which it is installed;
   (3) Preselect altitudes in increments that are commensurate with the
 altitudes at which the aircraft is operated;
   (4) Be tested without special equipment to determine proper operation of
 the alerting signals; and
   (5) Accept necessary barometric pressure settings if the system or device
 operates on barometric pressure. However, for operation below 3,000 feet AGL,
 the system or device need only provide one signal, either visual or aural, to
 comply with this paragraph. A radio altimeter may be included to provide the
 signal if the operator has an approved procedure for its use to determine DH
 or MDA, as appropriate.
   (c) Each operator to which this section applies must establish and assign
 procedures for the use of the altitude alerting system or device and each
 flight crewmember must comply with those procedures assigned to him.
   (d) Paragraph (a) of this section does not apply to any operation of an
 airplane that has an experimental certificate or to the operation of any
 airplane for the following purposes:
   (1) Ferrying a newly acquired airplane from the place where possession of
 it was taken to a place where the altitude alerting system or device is to be
 installed.
   (2) Continuing a flight as originally planned, if the altitude alerting
 system or device becomes inoperative after the airplane has taken off;
 however, the flight may not depart from a place where repair or replacement
 can be made.
   (3) Ferrying an airplane with any inoperative altitude alerting system or
 device from a place where repairs or replacements cannot be made to a place
 where it can be made.
   (4) Conducting an airworthiness flight test of the airplane.
   (5) Ferrying an airplane to a place outside the United States for the
 purpose of registering it in a foreign country.
   (6) Conducting a sales demonstration of the operation of the airplane.
   (7) Training foreign flight crews in the operation of the airplane before
 ferrying it to a place outside the United States for the purpose of
 registering it in a foreign country.

   Effective Date Note: At 54 FR 34291, August 18, 1989, Sec. 91.219 was
 added effective August 18, 1990.






 Sec. 91.221  Traffic alert and collision avoidance system equipment anduse.

   (a) All airspace: U.S.-registered civil aircraft. Any traffic alert and
 collision avoidance system installed in a U.S.-registered civil aircraft must
 be approved by the Administrator.
   (b) Traffic alert and collision avoidance system, operation required. Each
 person operating an aircraft equipped with an operable traffic alert and
 collision avoidance system shall have that system on and operating.

   Effective Date Note: At 54 FR 34291, August 18, 1989, Sec. 91.221 was

 Sec. 91.301   Applicability; relation to Part 36.

   (a) This subpart prescribes operating noise limits and related requirements
 that apply, as follows, to the operation of civil aircraft in the United
 States:
   (1) Sections 91.303, 91.305, 91.306, and 91.307 apply to civil subsonic
 turbojet airplanes with maximum weights of more than 75,000 pounds and--
   (i) If U.S. registered, that have standard airworthiness certificates; or
   (ii) If foreign registered, that would be required by this chapter to have
 a U.S. standard airworthiness certificate in order to conduct the operations
 intended for the airplane were it registered in the United States.

 Those sections apply to operations to or from airports in the United States
 under this part and Parts 121, 123, 129, and 135 of this chapter.
   (2) Section 91.308 applies to U.S. operators of civil subsonic turbojet
 airplanes covered by this subpart. That section applies to operators
 operating to or from airports in the United States under this part and Parts
 121, 123, 125, and 135 but not to those operating under Part 129 of this
 chapter.
   (3) Sections 91.302, 91.309 and 91.311 apply to U.S. registered civil
 supersonic airplanes having standard airworthiness certificates, and to
 foreign registered civil supersonic airplanes that, if registered in the
 United States, would be required by this chapter to have a U.S. standard
 airworthiness certificate in order to conduct the operations intended for the
 airplane. Those sections apply to operations under this part and under Parts
 121, 123, 125, 129, and 135 of this chapter.
   (b) Unless otherwise specified, as used in this subpart "Part 36" refers to
 14 CFR Part 36, including the noise levels under Appendix C of that part,
 notwithstanding the provisions of that part excepting certain airplanes from
 the specified noise requirements. For purposes of this subpart, the various
 stages of noise levels, the terms used to describe airplanes with respect to
 those levels, and the terms "subsonic airplane" and "supersonic airplane"
 have the meanings specified under Part 36 of this chapter. For purposes of
 this subpart, for subsonic airplanes operated in foreign air commerce in the
 United States, the Administrator may accept compliance with the noise
 requirements under Annex 16 of the International Civil Aviation Organization
 when those requirements have been shown to be substantially compatible with,
 and achieve results equivalent to those achievable under, Part 36 for that
 airplane. Determinations made under these provisions are subject to the
 limitations of Sec. 36.5 of this chapter as if those noise levels were Part
 36 noise levels.

 56 FR 65638, No. 242, Dec. 17, 1991

   SUMMARY: This final rule amends the Federal Aviation Regulations (FAR) to
 adopt certain recommendations of the National Airspace Review (NAR)
 concerning changes to regulations and procedures in regard to airspace
 classifications. These changes are intended to: (1) Simplify airspace
 designations; (2) achieve international commonality of airspace designations;
 (3) increase standardization of equipment requirements for operations in
 various classifications of airspace; (4) describe appropriate pilot
 certificate requirements, visual flight rules (VFR) visibility and distance
 from cloud rules, and air traffic services offered in each class of airspace;
 and (5) satisfy the responsibilities of the United States as a member of the
 International Civil Aviation Organization (ICAO). The final rule also amends
 the requirement for minimum distance from clouds in certain airspace areas
 and the requirements for communications with air traffic control (ATC) in
 certain airspace areas; eliminates airport radar service areas (ARSAs),
 control zones, and terminal control areas (TCAs) as airspace classifications;
 and eliminates the term "airport traffic area." The FAA believes simplified
 airspace classifications will reduce existing airspace complexity and thereby
 enhance safety.

   EFFECTIVE DATE: These regulations become effective September 16, 1993,
 except that Secs. 11.61(c), 91.215(d), 71.601, 71.603, 71.605, 71.607, and
 71.609 and Part 75 become effective December 12, 1991, and except that
 amendatory instruction number 20, Sec. 71.1 is effective as of September 15,
 1993, and that Secs. 71.11 and 71.19 become effective October 15, 1992. The
 incorporation by reference of FAA Order 7400.7 in Sec. 71.1 (amendatory
 instruction number 20) is approved by the Director of the Federal Register
 as of December 17, 1991, through September 15, 1993. The incorporation by
 reference of FAA Order 7400.9 in Sec. 71.1 (amendatory instruction number 24)
 is approved by the Director of the Federal Register as of September 16,
 1993 through September 15, 1994.

 57 FR 19350, No. 87, May 5, 1992

 SUMMARY: This final rule amends the Federal Aviation Regulations to allow
 part 91 operators to continue flight, or ferry certain aircraft, in the event
 that the flight recorder (FR) and/or cockpit voice recorder (CVR) is
 inoperable. This change provides part 91 operators similar relief to that
 afforded air carriers and commercial operators operating under part 91 of the
 Federal Aviation Regulations (FAR). Additionally, this change permits part 91
 operators to operate for up to 15 days with an inoperative FR or CVR. These
 amendments are intended to prevent part 91 operations from being forced out
 of service unnecessarily.

 EFFECTIVE DATE: May 5, 1992.

 flight in accordance with paragraph (b) or (c) of this section, as
 appropriate. However, each operator who before November 19, 1966, has shown
 that a model of airplane with an engine inoperative is satisfactory for safe
 flight by a test flight conducted in accordance with performance data
 contained in the applicable Airplane Flight Manual under paragraph (a)(2) of
 this section need not repeat the test flight for that model.
   (2) The approved Airplane Flight Manual contains the following performance
 data and the flight is conducted in accordance with that data:
   (i) Maximum weight.
   (ii) Center of gravity limits.
   (iii) Configuration of the inoperative propeller (if applicable).
   (iv) Runway length for takeoff (including temperature accountability).
   (v) Altitude range.
   (vi) Certificate limitations.
   (vii) Ranges of operational limits.
   (viii) Performance information.
   (ix) Operating procedures.
   (3) The operator has FAA approved procedures for the safe operation of the
 airplane, including specific requirements for--
   (i) Limiting the operating weight on any ferry flight to the minimum
 necessary for the flight plus the necessary reserve fuel load;
   (ii) A limitation that takeoffs must be made from dry runways unless, based
 on a showing of actual operating takeoff techniques on wet runways with one
 engine inoperative, takeoffs with full controllability from wet runways have
 been approved for the specific model aircraft and included in the Airplane
 Flight Manual:
   (iii) Operations from airports where the runways may require a takeoff or
 approach over populated areas; and
   (iv) Inspection procedures for determining the operating condition of the
 operative engines.
   (4) No person may take off an airplane under this section if--
   (i) The initial climb is over thickly populated areas; or
   (ii) Weather conditions at the takeoff or destination airport are less than
 those required for VFR flight.
   (5) Persons other than required flight crewmembers shall not be carried
 during the flight.
   (6) No person may use a flight crewmember for flight under this section
 unless that crewmember is thoroughly familiar with the operating procedures
 for one-engine inoperative ferry flight contained in the certificate holder's
 manual and the limitations and performance information in the Airplane Flight
 Manual.
   (b) Flight tests: reciprocating-engine-powered airplanes. The airplane
 performance of a reciprocating-engine-powered airplane with one engine
 inoperative must be determined by flight test as follows:
   (1) A speed not less than 1.3 VS1 must be chosen at which the airplane may
 be controlled satisfactorily in a climb with the critical engine inoperative
 (with its propeller removed or in a configuration desired by the operator and
 with all other engines operating at the maximum power determined in paragraph
 (b)(3) of this section.
   (2) The distance required to accelerate to the speed listed in paragraph
 (b)(1) of this section and to climb to 50 feet must be determined with--
   (i) The landing gear extended;
   (ii) The critical engine inoperative and its propeller removed or in a
 configuration desired by the operator; and
   (iii) The other engines operating at not more than maximum power
 established under paragraph (b)(3) of this section.
   (3) The takeoff, flight and landing procedures, such as the approximate
 trim settings, method of power application, maximum power, and speed must be
 established.
   (4) The performance must be determined at a maximum weight not greater than
 the weight that allows a rate of climb of at least 400 feet per minute in the
 en route configuration set forth in Sec. 25.67(d) of this chapter in effect
 on January 31, 1977, at an altitude of 5,000 feet.
   (5) The performance must be determined using temperature accountability for
 the takeoff field length, computed in accordance with Sec. 25.61 of this
 chapter in effect on January 31, 1977.
   (c) Flight tests: Turbine-engine-powered airplanes. The airplane
 performance of a turbine-engine-powered airplane with one engine inoperative
 must be determined by flight tests, including at least three takeoff tests,
 in accordance with the following:
   (1) Takeoff speeds VR and V2, not less than the corresponding speeds under
 which the airplane was type certificated under Sec. 25.107 of this chapter,
 must be chosen at which the airplane may be controlled satisfactorily with
 the critical engine inoperative (with its propeller removed or in a
 configuration desired by the operator, if applicable) and with all other
 engines operating at not more than the power selected for type certification
 as set forth in Sec. 25.101 of this chapter.
   (2) The minimum takeoff field length must be the horizontal distance
 required to accelerate and climb to the 35-foot height at V2 speed (including
 any additional speed increment obtained in the tests) multiplied by 115
 percent and determined with--
   (i) The landing gear extended;
   (ii) The critical engine inoperative and its propeller removed or in a
 configuration desired by the operator (if applicable); and
   (iii) The other engine operating at not more than the power selected for
 type certification as set forth in Sec. 25.101 of this chapter.
   (3) The takeoff, flight, and landing procedures such as the approximate
 trim setting, method of power application, maximum power, and speed must be
 established. The airplane must be satisfactorily controllable during the
 entire takeoff run when operated according to these procedures.
   (4) The performance must be determined at a maximum weight not greater than
 the weight determined under Sec. 25.121(c) of this chapter but with--
   (i) The actual steady gradient of the final takeoff climb requirement not
 less than 1.2 percent at the end of the takeoff path with two critical
 engines inoperative; and
   (ii) The climb speed not less than the two-engine inoperative trim speed
 for the actual steady gradient of the final takeoff climb prescribed by
 paragraph (c)(4)(i) of this section.
   (5) The airplane must be satisfactorily controllable in a climb with two
 critical engines inoperative. Climb performance may be shown by calculations
 based on, and equal in accuracy to, the results of testing.
   (6) The performance must be determined using temperature accountability for
 takeoff distance and final takeoff climb computed in accordance with Sec.
 25.101 of this chapter.

 For the purpose of paragraphs (c)(4) and (5) of this section, "two critical
 engines" means two adjacent engines on one side of an airplane with four
 engines, and the center engine and one outboard engine on an airplane with
 three engines.

 56 FR 65638, No. 242, Dec. 17, 1991

   SUMMARY: This final rule amends the Federal Aviation Regulations (FAR) to
 adopt certain recommendations of the National Airspace Review (NAR)
 concerning changes to regulations and procedures in regard to airspace
 classifications. These changes are intended to: (1) Simplify airspace
 designations; (2) achieve international commonality of airspace designations;
 (3) increase standardization of equipment requirements for operations in
 various classifications of airspace; (4) describe appropriate pilot
 certificate requirements, visual flight rules (VFR) visibility and distance
 from cloud rules, and air traffic services offered in each class of airspace;
 and (5) satisfy the responsibilities of the United States as a member of the
 International Civil Aviation Organization (ICAO). The final rule also amends
 the requirement for minimum distance from clouds in certain airspace areas
 and the requirements for communications with air traffic control (ATC) in
 certain airspace areas; eliminates airport radar service areas (ARSAs),
 control zones, and terminal control areas (TCAs) as airspace classifications;
 and eliminates the term "airport traffic area." The FAA believes simplified
 airspace classifications will reduce existing airspace complexity and thereby
 enhance safety.

   EFFECTIVE DATE: These regulations become effective September 16, 1993,
 except that Secs. 11.61(c), 91.215(d), 71.601, 71.603, 71.605, 71.607, and
 71.609 and Part 75 become effective December 12, 1991, and except that
 amendatory instruction number 20, Sec. 71.1 is effective as of September 15,
 1993, and that Secs. 71.11 and 71.19 become effective October 15, 1992. The
 incorporation by reference of FAA Order 7400.7 in Sec. 71.1 (amendatory
 instruction number 20) is approved by the Director of the Federal Register
 as of December 17, 1991, through September 15, 1993. The incorporation by
 reference of FAA Order 7400.9 in Sec. 71.1 (amendatory instruction number 24)
 is approved by the Director of the Federal Register as of September 16,
 1993 through September 15, 1994.

 subsonic turbojet airplanes with maximum weights of more than 75,000 pounds
 and--
   (i) If U.S. registered, that have standard airworthiness certificates; or
   (ii) If foreign registered, that would be required by this chapter to have
 a U.S. standard airworthiness certificate in order to conduct the operations
 intended for the airplane were it registered in the United States. Those
 sections apply to operations to or from airports in the United States under
 this part and parts 121, 125, 129, and 135 of this chapter.
   (2) Section 91.813 applies to U.S. operators of civil subsonic turbojet
 airplanes covered by this subpart. This section applies to operators
 operating to or from airports in the United States under this part and parts
 121, 125, and 135, but not to those operating under part 129 of this chapter.
   (3) Sections 91.803, 91.819, and 91.821 apply to U.S.-registered civil
 supersonic airplanes having standard airworthiness certificates and to
 foreign-registered civil supersonic airplanes that, if registered in the
 United States, would be required by this chapter to have U.S. standard
 airworthiness certificates in order to conduct the operations intended for
 the airplane. Those sections apply to operations under this part and under
 parts 121, 125, 129, and 135 of this chapter.
   (b) Unless otherwise specified, as used in this subpart "part 36" refers to
 14 CFR part 36, including the noise levels under appendix C of that part,
 notwithstanding the provisions of that part excepting certain airplanes from
 the specified noise requirements. For purposes of this subpart, the various
 stages of noise levels, the terms used to describe airplanes with respect to
 those levels, and the terms "subsonic airplane" and "supersonic airplane"
 have the meanings specified under part 36 of this chapter. For purposes of
 this subpart, for subsonic airplanes operated in foreign air commerce in the
 United States, the Administrator may accept compliance with the noise
 requirements under annex 16 of the International Civil Aviation Organization
 when those requirements have been shown to be substantially compatible with,
 and achieve results equivalent to those achievable under, part 36 for that
 airplane. Determinations made under these provisions are subject to the
 limitations of Sec. 36.5 of this chapter as if those noise levels were part
 36 noise levels.
   (c) Sections 91.851 through 9l.875 of this subpart prescribe operating
 noise limits and related requirements that apply to any civil subsonic
 turbojet airplane with a maximum certificated weight of more than 75,000
 pounds operating to or from an airport in the 48 contiguous United States and

 number of owned or leased Stage 2 airplanes subject to Sec. 91.801(c) of this
 subpart that were listed on that operator's operations specifications for
 operations to or from airports in the contiguous United States on any one day
 selected by the operator during the period January 1, 1990, through July 1,
 1991, plus or minus adjustments made pursuant to paragraphs (a) (1) and (2).
   (1) The base level of a U.S. operator shall be increased by a number equal
 to the total of the following--
   (i) The number of Stage 2 airplanes returned to service in the United
 States pursuant to Sec. 91.855(f);
   (ii) The number of Stage 2 airplanes purchased pursuant to Sec. 91.855(g);
 and
   (iii) Any U.S. operator base level acquired with a Stage 2 airplane
 transferred from another person under Sec. 91.863.
   (2) The base level of a U.S. operator shall be decreased by the amount of
 U.S. operator base level transferred with the corresponding number of Stage 2
 airplanes to another person under Sec. 91.863.
   (b) Foreign air carriers. The base level of a foreign air carrier is equal
 to the number of owned or leased Stage 2 airplanes that were listed on that
 carrier's U.S. operations specifications on any one day during the period
 January 1, 1990, through July 1, 1991, plus or minus any adjustments to the
 base levels made pursuant to paragraphs (b) (1) and (2).
   (1) The base level of a foreign air carrier shall be increased by the
 amount of foreign air carrier base level acquired with a Stage 2 airplane
 from another person under Sec. 91.863.
   (2) The base level of a foreign air carrier shall be decreased by the
 amount of foreign air carrier base level transferred with a Stage 2 airplane

 Sec. 91.863  Transfers of Stage 2 airplanes with base level.

   (a) Stage 2 airplanes may be transferred with or without the corresponding
 amount of base level. Base level may not be transferred without the
 corresponding number of Stage 2 airplanes.
   (b) No portion of a U.S. operator's base level established under Sec.
 91.861(a) may be used for operations by a foreign air carrier. No portion of
 a foreign air carrier's base level established under Sec. 91.861(b) may be
 used for operations by a U.S. operator.
   (c) Whenever a transfer of Stage 2 airplanes with base level occurs, the
 transferring and acquiring parties shall, within 10 days, jointly submit
 written notification of the transfer to the FAA, Office of Environment and
 Energy. Such notification shall state:
   (1) The names of the transferring and acquiring parties;
   (2) The name, address, and telephone number of the individual responsible
 for submitting the notification on behalf of the transferring and acquiring
 parties;
   (3) The total number of Stage 2 airplanes transferred, listed by airplane
 type, model, series, and serial number;
   (4) The corresponding amount of base level transferred and whether it is
 U.S. operator or foreign air carrier base level; and
   (5) The effective date of the transaction.
   (d) If, taken as a whole, a transaction or series of transactions made
 pursuant to this section does not produce an increase or decrease in the
 number of Stage 2 airplanes for either the acquiring or transferring
 operator, such transaction or series of transactions may not be used to
 establish compliance with the requirements of Sec. 91.865.

 56 FR 65638, No. 242, Dec. 17, 1991

   SUMMARY: This final rule amends the Federal Aviation Regulations (FAR) to
 adopt certain recommendations of the National Airspace Review (NAR)
 concerning changes to regulations and procedures in regard to airspace
 classifications. These changes are intended to: (1) Simplify airspace
 designations; (2) achieve international commonality of airspace designations;
 (3) increase standardization of equipment requirements for operations in
 various classifications of airspace; (4) describe appropriate pilot
 certificate requirements, visual flight rules (VFR) visibility and distance
 from cloud rules, and air traffic services offered in each class of airspace;
 and (5) satisfy the responsibilities of the United States as a member of the
 International Civil Aviation Organization (ICAO). The final rule also amends
 the requirement for minimum distance from clouds in certain airspace areas
 and the requirements for communications with air traffic control (ATC) in
 certain airspace areas; eliminates airport radar service areas (ARSAs),
 control zones, and terminal control areas (TCAs) as airspace classifications;
 and eliminates the term "airport traffic area." The FAA believes simplified
 airspace classifications will reduce existing airspace complexity and thereby
 enhance safety.

   EFFECTIVE DATE: These regulations become effective September 16, 1993,
 except that Secs. 11.61(c), 91.215(d), 71.601, 71.603, 71.605, 71.607, and
 71.609 and Part 75 become effective December 12, 1991, and except that
 amendatory instruction number 20, Sec. 71.1 is effective as of September 15,
 1993, and that Secs. 71.11 and 71.19 become effective October 15, 1992. The
 incorporation by reference of FAA Order 7400.7 in Sec. 71.1 (amendatory
 instruction number 20) is approved by the Director of the Federal Register
 as of December 17, 1991, through September 15, 1993. The incorporation by
 reference of FAA Order 7400.9 in Sec. 71.1 (amendatory instruction number 24)
 is approved by the Director of the Federal Register as of September 16,
 1993 through September 15, 1994.

      Appendix B to Part 91--Authorizations to Exceed Mach 1 (Sec. 91.55)

   Section 1. Application. (a) An applicant for an authorization to exceed
 mach 1 must apply in a form and manner prescribed by the Administrator and
 must comply with this appendix.
   (b) In addition, each application for an authorization to exceed mach 1
 covered by section 2(a) of this appendix must contain all information,
 requested by the Administrator, that he deems necessary to assist him in
 determining whether the designation of a particular test area, or issuance of
 a particular authorization, is a "major Federal action significantly
 affecting the quality of the human environment" within the meaning of the
 National Environmental Policy Act of 1969 (42 U.S.C. 4321 et seq.), and to
 assist him in complying with that Act, and with related Executive orders,
 guidelines, and orders, prior to such action.
   (c) In addition, each application for an authorization to exceed mach 1
 covered by section 2(a) of this appendix must contain--
   (1) Information showing that operation at a speed greater than mach 1 is
 necessary to accomplish one or more of the purposes specified in section 2(a)
 of this appendix, including a showing that the purpose of the test cannot be
 safely or properly accomplished by overocean testing;
   (2) A description of the test area proposed by the applicant, including an
 environmental analysis of that area meeting the requirements of paragraph (b)
 of this section; and
   (3) Conditions and limitations that will insure that no measurable sonic
 boom overpressure will reach the surface outside of the designated test area.
   (d) An application is denied if the Administrator finds that such action is
 necessary to protect or enhance the environment.
   Sec. 2. Issuance. (a) For a flight in a designated test area, an
 authorization to exceed mach 1 may be issued when the Administrator has taken
 the environmental protective actions specified in section 1(b) of this
 appendix, and the applicant shows one or more of the following:
   (1) The flight is necessary to show compliance with airworthiness
 requirements.
   (2) The flight is necessary to determine the sonic boom characteristics of
 the airplane, or is necessary to establish means of reducing or eliminating
 the effects of sonic boom.
   (3) The flight is necessary to demonstrate the conditions and limitations
 under which speeds greater than a true flight mach number of 1 will not cause
 a measurable sonic boom overpressure to reach the surface.
   (b) For a flight outside of a designated test area, an authorization to
 exceed mach 1 may be issued if the applicant shows conservatively under
 paragraph (a)(3) of this section that--
   (1) The flight will not cause a measurable sonic boom overpressure to reach
 the surface when the aircraft is operated under conditions and limitations
 demonstrated under paragraph (a)(3) of this section; and
   (2) Those conditions and limitations represent all foreseeable operating
 conditions.
   Sec. 3. Duration. (a) An authorization to exceed mach 1 is effective until
 it expires or is surrendered, or until it is suspended or terminated by the
 Administrator. Such an authorization may be amended or suspended by the
 Administrator at any time if he finds that such action is necessary to
 protect the environment. Within 30 days of notification of amendment, the
 holder of the authorization must request reconsideration or the amendment
 becomes final. Within 30 days of notification of suspension, the holder of
 the authorization must request reconsideration or the authorization is
 automatically terminated. If reconsideration is requested within the 30-day
 period, the amendment or suspension continues until the holder shows why, in
 his opinion, the authorization should not be amended or terminated. Upon such
 showing, the Administrator may terminate or amend the authorization if he
 finds that such action is necessary to protect the environment, or he may
 reinstate the authorization without amendment if he finds that termination or
 amendment is not necessary to protect the environment.
   (b) Findings and actions by the Administrator under this section do not
 affect any certificate issued under title VI of the Federal Aviation Act of
 1958.

 Appendix C to Part 91--Operations in the North Atlantic (NAT) Minimum
     Navigation Performance Specifications (MNPS) Airspace

   Section 1. NAT MNPS airspace is that volume of airspace between FL 275 and
 FL 400 extending between latitude 27 degrees north and the North Pole,
 bounded in the east by the eastern boundaries of control areas Santa Maria
 Oceanic, Shanwick Oceanic, and Reykjavik Oceanic and in the west by the
 western boundary of Reykjavik Oceanic Control Area, the western boundary of
 Gander Oceanic Control Area, and the western boundary of New York Oceanic
 Control Area, excluding the areas west of 60 degrees west and south of 38
 degrees 30 minutes north.
   Section 2. The navigation performance capability required for aircraft to
 be operated in the airspace defined in Sec. 1 of this appendix is as follows:
   (a) The standard deviation of lateral track errors shall be less than 6.3
 NM (11.7 Km). Standard deviation is a statistical measure of data about a
 mean value. The mean is zero nautical miles. The overall form of data is such
 that the plus and minus one standard deviation about the mean encompasses
 approximately 68 percent of the data and plus or minus two deviations
 encompasses approximately 95 percent.
   (b) The proportion of the total flight time spent by aircraft 30 NM (55.6
 Km) or more off the cleared track shall be less than 5.3 x 10-4 (less than
 one hour in 1,887 flight hours).
   (c) The proportion of the total flight time spent by aircraft between 50 NM
 and 70 NM (92.6 Km and 129.6 Km) off the cleared track shall be less than 13
 x 10-5 (less than one hour in 7,693 flight hours).
   Section 3. Air traffic control (ATC) may authorize an aircraft operator to
 deviate from the requirements of Sec. 91.20 for a specific flight if, at the
 time of flight plan filing for that flight, ATC determines that the aircraft
 may be provided appropriate separation and that the flight will not interfere
 with, or impose a burden upon, the operations of other aircraft which meet
 the requirements of Sec. 91.20.

 59 FR 2918, No. 12, Jan. 19, 1994

 SUMMARY: This action amends appendix D, part 91, of the Federal Aviation
 Regulations to accurately reflect the name of the new Denver, Colorado,
 airport. The new Denver International Airport, scheduled to open in March
 1994, will replace the Denver Stapleton Airport. Appendix D, part 91, lists
 locations, including Denver, Colorado, where special operating restrictions
 apply. This action will not affect any procedures or practices currently in
 place, but it is necessary to correctly state the name of the new Denver
 airport.

 EFFECTIVE DATE: March 9, 1994.
