Fatigue in Long-Haul Operations
Sponsor: National Aeronautics and Space Administration (NASA)
Summary
The purpose of the present study is to test novel countermeasures to reduce fatigue among airline pilots during long-haul flight operations. The investigators will collect objective and subjective sleep, sleepiness, workload, and performance data from active-duty line pilots flying long-haul flight operations (\>8 hours). Data will be collected during days off prior to the trip start, during flights and layover, and during days off following the trip end.
