Fatigue risk to the pilot has been a deterrent for conducting direct flights longer than 12 h under normal conditions, but such flights were a necessity during the COVID-19 pandemic. Twenty (N = 20) pilots flying across five humanitarian missions between Brazil and China wore a sleep-tracking device (the Zulu watch), which has been validated for the estimation of sleep timing (sleep onset and offset), duration, efficiency, and sleep score (wake, interrupted, light, or deep Sleep) throughout the mission period. Pilots also reported sleep timing, duration, and subjective quality of their in-flight rest periods using a sleep diary. To our knowledge, this is the first report of commercial pilot sleep behavior during ultra-long-range operations under COVID-19 pandemic conditions. Moreover, these analyses provide an estimate of sleep score during in-flight sleep, which has not been reported previously in the literature.
在正常情况下，飞行员的疲劳风险一直是阻碍进行超过12小时直飞航班的因素，但在新冠疫情期间，此类航班却必不可少。20名执行巴西与中国之间五项人道主义任务的飞行员佩戴了睡眠追踪设备（祖鲁手表），该设备已被验证可在整个任务期间估算睡眠时间（入睡和起床时间）、时长、效率和睡眠评分（清醒、中断、浅睡眠或深睡眠）。飞行员还使用睡眠日记报告飞行途中休息时段的睡眠时间、时长和主观质量。据我们所知，这是首篇关于新冠疫情期间超长航程商业飞行中飞行员睡眠行为的报告。此外，这些分析提供了飞行中睡眠评分的估算结果，此前文献中尚无相关报道。
