How flight crews organize their sleep during layovers on long-haul trips isdocumented. Additionally, environmental and physiological constraints on sleep are examined.

The circadian system had a greater influence on the timing and duration of first-sleeps than second-sleeps. There was also a preference for sleeping during the local night. The time of falling asleep for second-sleeps was related primarily to the amount of sleep already obtained in the layover, and their duration depended on the amount of time remaining in the layover.
