This study tested whether simulator-based training of pilot responses to unexpected or novel events can be improved by including unpredictability and variability in training scenarios.
Current regulations allow for highly predictable and invariable training, which may not be sufficient to prepare pilots for unexpected or novel situations in-flight. Training for surprise will become mandatory in the near future.
Using an aircraft model largely unfamiliar to the participants, one group of 10 pilots (the unpredictable and variable [U/V] group) practiced responses to controllability issues in a relatively U/V manner. A control group of another 10 pilots practiced the same failures in a highly predictable and invariable manner. After the practice, performance of all pilots was tested in a surprise scenario, in which the pilots had to apply the learned knowledge. To control for surprise habituation and familiarization with the controls, two control tests were included.
Whereas the U/V group required more time than the control group to identify failures during the practice, the results indicated superior understanding and performance in the U/V group as compared to the control group in the surprise test. There were no significant differences between the groups in surprise or performance in the control tests.
Given the results, we conclude that organizing pilot training in a more U/V way improves transfer of training to unexpected situations in-flight.
The outcomes suggest that the inclusion of U/V simulator training scenarios is important when training pilots for unexpected situations.
本研究旨在测试在模拟培训中增加不确定性和变异性是否能提高飞行员对意外或新事件的反应能力。
目前的规定允许进行高度可预测且不变的训练,这可能不足以让飞行员为飞行中的意外或新情况做好准备。未来不久,对意外情况的培训将成为强制性要求。
使用一种参与者相对不熟悉的飞机模型,一组 10 名飞行员(不可预测和可变组)以相对不可预测和可变的方式练习应对可控性问题的反应。另一组 10 名飞行员作为对照组,以高度可预测且不变的方式练习相同的故障。练习后,所有飞行员都在一个意外场景中进行了测试,他们必须在其中应用所学的知识。为了控制意外习惯和对控制的熟悉程度,还包括了两个对照测试。
虽然不可预测和可变组在练习期间识别故障所需的时间比对照组多,但在意外测试中,与对照组相比,不可预测和可变组的表现表明他们对知识的理解和掌握更优。在意外和对照测试中,两组之间均无显著差异。
基于结果,我们得出结论,以更不可预测和可变的方式组织飞行员培训可以提高将培训转移到飞行中的意外情况的能力。
研究结果表明,在培训飞行员应对意外情况时,纳入不可预测和可变的模拟培训场景很重要。
