The effects of 34 hr of continuous wakefulness on flight performance, instrument scanning, subjective fatigue and EEG activity were measured. Ten fixed-wing pilots flew a series of 10 simulator profiles, and root-mean-square error was calculated for various flight parameters. Ocular scanning patterns were obtained by means of infrared tracking. The results showed that flying errors peaked after about 24-28 hr of continuous wakefulness, in line with peaks in subjective- and EEG-measured fatigue. Instrument scanning was very consistent across pilots but was mostly unaffected by the sleep deprivation.
