Flight-stress appraisal was made by means of a battery of |
|
urinary determinations (epinephrine, norepinephrine, 17- |
|
OHCS, urea, uric acid, phosphorus, magnesium, sodium, and |
|
potassium) for flyers who participated in (a) 20-hour |
|
missions in C-130E aircraft (flights from New Zealand to |
|
Antarctica, and back), (b) 6-day missions in C-135B |
|
aircraft (earth-circling missions), or (c) 7-week |
|
missions in C-135B aircraft (over-frequent transoceanic |
|
and transcontinental flying). The adrenal medulla (as |
|
judged by urinary epinephrine) consistently showed flight- |
|
sensitivity, but other endocrine- metabolic functions |
|
varied in ways indicative of adaptation. With flight |
|
circumstances standardized (particularly with respect to |
|
time of day), flight effects tended to be reproducible. |
|
With crew rest limited to 2 days, recovery from flight- |
|
stress tended to be incomplete. Sleep deprivation and |
|
crew position were shown to be factors which modify |
|
flight-stress reactions. Eastbound and westbound earth- |
|
circling missions did not induce different degrees of |
|
flight- stress, as judged by these endocrine-metabolic |
|
indices. |
