HUMAN PERFORMANCE AND THE WORK-REST SCHEDULE

Abstract

This report contains a condensation of the material most relevent to the problem of work:rest 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- work:2-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.
