This Boeing film dates to the early 1970s and explains
the company's new Electronic Attitude Director Indicator
then under development. The EADI incorporated cutting
edge computer technology and was an early form of "glass
cockpit" technology. The EADI was developed in part
through work on Boeing's Supersonic Transport or SST. The
flight test program used a Model 80 outfitted with
cameras that picked up ground images. Includes shots of
Boeing aircraft including the 747 and 707 models.
Boeing's development of the Electronic Attitude Director
Indicator (EADI) stems from air traffic growth and the
need for better pilot information and control
capabilities. Originating from flight control issues
identified in Boeing's supersonic transport research in
1965, the EADI was created to address the limitations of
existing instruments, particularly for monitoring auto
land systems in low visibility. Using a visual flight
simulator and prototype testing in the 707 (Dash 80),
Boeing refined the EADI, incorporating features like
pitch increment lines, thrust management indicators, and
radio altimeters. The system was tested in various
locations, leading to improvements based on feedback from
airline representatives. The EADI also holds potential
for integrating advanced sensor outputs like radar or
micro vision. As a result, several avionics firms are now
developing similar systems for future airline use.
0:12 - Air traffic growth stimulates the development of
larger, faster aircraft and increased pilot
information/control capability.
0:43 - Boeing's research is focused on advances in
computer fields for navigation and control.
1:03 - Boeing's technical staff developed a new concept
for attitude director and landing situation information:
the EADI.
1:24 - The EADI concept evolved from flight control
problems in Boeing's supersonic transport research in
1965.
1:37 - Pilots requested a gross expansion of the pitch
indicator scale during test missions.
1:51 - Pilots reported limitations of existing
instruments for monitoring auto land systems in low
visibility.
2:09 - Development of the EADI concept began on a visual
flight simulator at Boeing's Kent, Washington facility.
2:26 - A breadboard instrument was mounted in the 707
prototype, known as the Dash 80.
2:35 - The display screen occupies the top center
position of the pilot's basic T panel.
3:06 - Control panel for symbol display; explanation of
the symbol format.
3:11 - Basic attitude display: fixed miniature airplane,
bold black horizon line, sky, and ground.
3:26 - Pitch increment lines: 10 degrees and 5 degrees.
3:44 - Roll commands: right and left.
3:53 - Computer-driven flight director symbols: fly
right, fly left, fly up, fly down, and zero commands.
4:29 - Airspeed error display: too fast, too slow, and on
reference.
4:44 - Actual flight path angle display: climbing, level
flight, and descending.
4:59 - Thrust management indicator: potential flight path
bar indicating thrust adequacy.
5:33 - Radio altimeter with a range of 780 feet; altitude
displayed in 10-foot increments down to 90 feet.
6:00 - ILS window for displaying raw localizer and
gliding information.
6:15 - Excessive deviation from the localizer and glide
slope.
6:52 - Crabbed approach problem handled with drift
sensors.
7:36 - TV input for viewing approach terrain with flight
path and pitch scale displays.
8:00 - EADI tested in various locations and in connection
with other programs.
8:32 - EADI demonstrated to airline representatives in
Wichita, Kansas, leading to improvements based on
feedback.
9:16 - EADI evaluated for use in steep angle noise
reduction approaches.
9:44 - Night landings tested under turbulent conditions
in Kansas.
10:38 - Simultaneous with breadboard testing, Boeing
invited bids for prototype EADI systems.
11:03 - Prototypes delivered to Boeing's developmental
center for extensive bench testing.
11:12 - Altimeters follow the same pattern as the
breadboard instrument.
11:40 - Adjustable pitch reference line added for visual
approaches.
12:00 - Potential for displaying advanced sensor outputs
like radar or micro vision.
12:31 - Several avionics firms developing similar EADI
systems for airline service use.
