An airborne power control system for automatically controlling the power of an aircraft during landing is disclssed. The system includes a computer and a minimum airspeed program as a function of altitude. A radio altimeter or the like senses the instantaneous altitude of the aircraft while a pitot tube or the like measures indicated airspeed. A computer and program compare programmed airspeed with actual airspeed for a given altitude. And, a servomotor is provided for decreasing engine thrust where the actual airspeed exceeds the programmed airspeed at any given altitude. An inhibitor inhibits the decrease in engine thrust if the airspeed drops below the programmed airspeed.

1. An airborne safe landing power control system for an aircraft including an autothrottle system with a landing mode and a minimum airspeed program as a function of altitude during a landing maneuver, a radio altimeter for sensing the instantaneous altitude of an aircraft, means for sensing the aircraft's airspeed and comparator means for comparing the programmed airspeed with the actual airspeed at a given altitude and throttle retard means for decreasing the engine thrust when the actual airspeed exceeds the programmed airspeed at any given altitude, and first inhibiting means for inhibiting the throttle retard means when the aircraft's altitude as determined by said radio altimeter indicates that the aircraft is above a preselected altitude for the start of a landing maneuver and second inhibiting means for inhibiting the throttle retard means if the airspeed drops below the programmed airspeed.
