Abstract:

This report contains a condensation of the material most relevent to the problem of workrest scheduling in advanced aerospace systems. The major conclusions drawn are a periods of wakefulness longer than 24 hours requiring performance of critical tasks are not feasible as a routine procedure b 6 hours of leep per day are adequate for most individuals c sleep p riods should not be less than 2 hours in duration d continuous performance of monotonous tasks by themselves should not exceed 2 hours e performance of active tasks may be extended to 10 hours f total cycle duration work plus rest should be 4, 6, 8, or 12 hours in order to permit regular day to day schedules g where stress will be high, schedules no more severe than 2- work2-rest or equivalent should be used h 7 or 8 days pretesting should be adequate to select persons adaptable to schedule changes i a 5-day preadaptation period should be used to overcome initial sleep losses.
