Abstract |
A major challenge for flight crews is the need to maintain vigilance during long, highly automated nighttime flights. A six-hour uneventful nighttime flight in a flight simulator was flown by 14 two-man crews. The 14 subjects in the treatment group received five short breaks spaced hourly during cruise; the 14 subjects in the control group received one break in the middle of cruise. During the latter part of the night, the treatment group showed significant reductions for 15min post-break in slow eye movements, theta-band activity and unintended sleep episodes compared with the control group. The treatment group reported significantly greater subjective alertness for up to 25min post-break, with strongest effects near the time of the circadian trough. The findings show the potential usefulness of short-duration breaks as an in-flight fatigue countermeasure. |
