CALCULATION AND DISPLAY OF WARNING SPEED FOR THRUST ASYMMETRY CONTROL

A system and a method for calculating and then displaying a minimum safe flight speed for an aircraft to maintain control under conditions of thrust asymmetry, and for providing flight path guidance and autopilot commands to maintain airspeed above this calculated minimum speed. The software of a flight control computer calculates the minimum safe speed in the presence of thrust asymmetry using data from existing aircraft sensors that are available for other reasons. The flight control computer outputs the calculation results to a display computer, which controls a cockpit display to indicate the warning speed to the pilot, and to the autopilot for use in generating autoflight commands for controlling the angular position of the elevators.
