1. A method of predicting the approaching stall of an aircraft wing, comprising:

  • sensing air speed over the wing at a predetermined location spaced above the top surface of the wing to thereby produce input signals representative of air speed fluctuations at said location, said fluctuations being caused by air turbulence over the wing;

    using said input signals to produce a signal represensative of a ratio of the air speed fluctuations to an average air speed; and

    using said ratio signal to produce a signal indicative of imminent stalling.
