Six experimental flying missions (each of 54 hours' duration) were flown in a C-141 aircraft. Two crews took turns flying the aircraft during each mission. The same two crews flew all six missions. In three of the missions the work/rest schedule was 4/4 hours; in the remaining missions it was 16/16 hours. Oral temperatures of 9 of the crewmembers (2 Aircraft Commanders, 2 Copilots, 2 Flight Engineers, 2 Navigators, and 1 Loadmaster) were measured at 4-hour intervals during the flight periods and also during 54-hour postflight periods, with the testing schedule standardized with respect to time of day. The oral temperature rhythm during flight periods, although remaining entrained to the time at the home base, was lower in amplitude than that during postflight periods (P less than .01). The 4/4 work/rest schedule had more depressant influence on oral temperature than the 16/16 schedule (P less than .005). Crew position was found to be a factor contributing to oral temperature variability (P less than .05). The individuals occupying key positions had the lowest oral temperatures during flight periods as well as during postflight periods. (Author)
