ABSTRACT:
An aircraft performance monitor 1 receives signals representative of the height h, rate of change of height h and vertical acceleration .theta. of the aircraft. The monitor 1 determines when (h-A(.sub.n.sbsb.1.sup.n.sbsp.2 +K.sub.1 h+K.sub.2 .theta. goes beyond a predetermined limit and generates a warning signal and disables the autopilot. The signal representative of vertical acceleration may be derived from the rate of change of pitch attitude of the aircraft, from the elevator angle or from an accelerometer.
