大型飞机在风切变环境中飞行安全尺度分析

Analysis of flight safety scale in windshear for large aircraft

基于低空风切变对飞行安全的影响,对大型飞机在风切变环境中的飞行安全尺度进行了详细分析。主要从风切变能量水平和飞行安全尺度进行比较,从而可以评估风切变的危险程度,而风切变的危险程度主要从风切变危险尺度和速度危险尺度来衡量。风切变危险程度如果达到飞机飞行安全尺度边界,飞机则会发出告警提示。飞行员根据告警提示采用相应的操纵方法避免危险的发生,从而提高飞机的飞行安全性。

The flight safety scale in low altitude windshear is analyzed based on the effect of low altitude windshear in flight safety in the detail.The danger level of windshear can be evaluated by comparing the energy level and flight safety scale.The danger level of the windshear is mainly measured from the danger scale of windshear and velocity.If the danger level of windshear reaches the boundary of flight safety scale,a warning signal will be givenk.The pilot will take corresponding measures according to the warning signal to prevent the dangerous situation,therefore,thus improving the flight safety.
