Influence on loss of control trend by pilot behavior changes during highland wind-field approach

The operation of highland airport flight safety is a research field with conspicuous Chinese characteristics. In the highland airport terminal area, the performance of the aircraft reduces. The probability of unsafe events and accidents increases, when encountering heavy winds and other adverse weather conditions. Loss of control (LoC) is one of the important conditions. To analyze the mechanism of flying out of control in wind-field and research the effect of plateau environmental behavior changes on LoC trend, we present parametric characterization of the pilot's manipulation of operation in highland airport terminal area and then simulate the potential impacts on pilot's behavior at high altitude. Binding a typical pattern highland wind-field, we analyze the risk of LoC when flying through wind by numerical simulation. The results show that dangerous valley winds and gusts are chief incitements causing uncontrolled flight. The pilot's physiological and psychological deterioration has a significant impact on the risk of LoC. Also, inappropriate gain, excessive delay and lag lead to the aircraft out of control. If we can provide targeted training for pilots, reduce the response gain to dangerous wind pattern and maintain proper tension to minimize control delay, it will help to deal with the wind disturbance and maintain the ability of completing a mission.
