Abstract Objective To investigate workload changes of subjects during simulated long-haul flights at daytime and nighttime. Methods Eight volunteers were completed the simulated long-haul flight experiments at the same time periods of day and night. The parameters of measurements included flight simulation performance, additional task performance, ratings of perceived exertion scale (RPE), Stanford Sleepiness Scale (SSS), and critical flicker fusion frequency (CFF). Results There were no significant changes of the simulated flight performance between daytime group and nighttime group. The achievement of additional task was significantly lower than that of the same time period in daytime group. RPE and SSS scores in nighttime group were increased and CFF decreased. Conclusions Simulated long-haul flight at nighttime could aggravate the flight workload and reduce the reserved operating capacity.
