由于超过临界迎角而导致的升力突然丧失。

摊位

机翼不会因为速度低而停止飞行,而是因为迎角过大。当迎角超过临界点时,气流会从上表面分离,升力消失,这就是失速。

失速可能发生在任何速度和任何姿态下。高速急转弯会导致外翼失速。突然拉杆也可能导致飞机在平飞中失速。关键因素始终是转弯角度,而非空速。

警告和恢复

训练重点在于识别和改出失速,因为进近或航线飞行中的失速每年都会造成飞行员丧生。现代客机配备了包线保护装置,在正常情况下可以完全避免这种情况的发生。

    Is a spin just a stalled wing with yaw or is there more to it?

    Recovering from a stall is one of the first things you practice. Angle of attack is the real key, not just airspeed.

    Sudden loss of lift is dramatic. Understanding why it happens makes the recovery procedure make sense.
