Continuous recordings were made of the EEG and ECG of one pilot during a series of instrument flights in a feeder-type transport aircraft. The flights were arranged to contain epochs of distinctly differing levels of workload. In addition, some flights were made after a night of sleep deprivation and others were made as the second and third flights of the day. Subjectively, there appeared to be marked differences in performance between the two types of tired flight. The EEG analyses showed changes that correlated well with differences in workload. In the highest workload areas during fresh flights, EEG activity increased by approximately a factor of 4 over that of the preflight resting values. This large increase did not occur in the tired flights. Further experiments are planned using flights in aircraft and in simulators using several subjects.
在一架支线运输机上，对一名飞行员在一系列仪表飞行过程中的脑电图（EEG）和心电图（ECG）进行了连续记录。这些飞行被安排为包含不同工作负荷水平的时间段。此外，一些飞行是在一夜睡眠剥夺后进行的，而其他飞行则是在一天中的第二次和第三次飞行时进行的。主观上，两种疲劳飞行状态下的表现似乎存在明显差异。脑电图分析显示的变化与工作负荷的差异密切相关。在清醒飞行的最高工作负荷区域，脑电图活动比飞行前静息值增加了约4倍。而在疲劳飞行中并未出现这种大幅增加。计划使用多名受试者在飞机和模拟器上进行进一步的实验。
