Abstract
A method of predicting the approaching stall of an aircraft wing which is dependent on an inherent characteristic of the airflow as the stall is approached. The method described uses a hot-wire probe which measures the turbulence of the airflow at a predetermined location on the top surface of the wing. When the turbulence exceeds a threshold, which threshold is dependent on the air-speed, a signal is produced which indicates that a stall is imminent. The method can be particularly applied to an artificial stall warning device fitted to a transport aircraft.
