本航空航天标准涵盖两个基本失速警告系统，一个测量机翼上的气流和压力分布，另一个测量气流相对于任意基准线的角度。每种类型的系统至少包括一个传感器和一个装置，用于激活一个警告飞行员即将失速的装置。

This Aerospace Standard covers two basic Stall Warning Systems, one measures air flow and pressure distribution on the airfoil and the other measures the angle of airflow with respect to an arbitrary reference line. Each type of system includes, as a minimum, a sensor and the means for activating a device which warns the pilot of an impending stall.
