起飞延误时间的不确定性对飞行模拟训练任务的影响

Effects of Delay Uncertainty on Flight Simulation Training

研究探讨了在飞行模拟任务中起飞延误时间的不确定性对于操纵者生理心理的影响。本文通过实验的方法要求所有被试均接受起飞延误时间确定和不确定两种情景的任务。记录被试在执行起飞任务中的心率、呼吸及起飞任务完成后的简单反应时测试成绩,并要求被试在完成延误时间不确定起飞任务后对起飞等待时间进行主观估计。数据经配对样本T检验后发现,被试在明确被告知具体等待时间的任务中表现出更加平稳和放松的生理状态并呈现出更低的心理疲劳程度,在未被明确告知具体等待时间的任务中表现出相反的生理及心理状况并表现出对等待时间显著高估的现象。结论认为在飞行模拟训练任务中起飞延误时间的不确定性对操纵者生理及心理的紧张程度和疲劳水平存在显著影响。

This study aims to discuss how uncertainty of off-delay time influences the operator both physically and mentally in flight training tasks. The study was conducted by experiments and all participants were subjected to two kinds of situations （certain time delay, uncertain time delay）. Their heart rate, respiratory rhythm during take-off task, performance in simple reaction time test after task and subjective estimation of delay time were recorded. These data were then analyzed by the paired samples T test. Results show that participants, who are informed of certain delay time, are smooth and more relaxed physiologically with lower degree of mental fatigue. The conclusion indicates that uncertainty of delay time has significant effects on flight simulation training.
