Pilot\u2019s sleep\/wake history was measured with actigraphy and verified by logbook across 8\u20139\n d.<jats:bold>RESULTS:<\/jats:bold> Pilots averaged 8.210 \u00b1 1.687 SD hours of sleep per 24 h across the study period. A logistic model of the circadian timing of sleep indicated that time of day and phase of trip are significant predictors of pilots being asleep. Significant two- and three-way interactions\n were found between time of day, phase of trip, and route. A significant difference in average sleep time was observed between baseline and recovery day 1 for one route. All other recovery days and routes were not significantly different from baseline.<jats:bold>DISCUSSION:<\/jats:bold> For the four routes,\n the average amount of sleep per 24-h period during the study period was within the normal range with the circadian rhythm aligned to home-base time pre- and post-trip. Flight segments and layover conditions were associated with a misalignment of sleep relative to circadian rhythm, with layover\n sleep appearing to shift toward the local night. Full post-trip sleep duration recovery appears to occur for all routes within 1\u20132 d.<jats:bold>Lamp A, McCullough D, Chen JMC, Brown RE, Belenky G. <jats:italic>Pilot sleep in long-range and ultra-long-range commercial flights<\/jats:italic>.
