Fatigue is a frequent phenomenon for pilots doing shiftwork and working in changing time zones. Napping or increased cockpit lighting,so-called in-flight countermeasures, may help pilots mitigate the symptoms ofacute fatigue. This study investigated the impact of napping on sleep qualityand the effect of in-flight countermeasures on how often pilots notice fatiguesymptoms when feeling tired. In total, 106 German-speaking pilots participatedin an online survey. The results showed a medium correlation between napping andimproved sleep quality (r = .32) and a low-to-mediumcorrelation between a frequent usage of in-flight countermeasures and less acutephysical fatigue symptoms (r = −.22). Officers indicateusing napping more often than captains do (d = .70). Furtherresearch should investigate how cabin crew members can benefit from mitigatingmeasures.
