Abstract:
A method augmenting a pilot's command lane signal by transmitting the pilot's input command to a first summer (13) and the surface actuator control circuitry (17). The first summer output signal (113) is transmitted to a second summer circuit (15) to add (or subtract) the first summer output signal with a flight control signal (119) resulting in a second summer output signal (115). The second summer output signal is transmitted (115) to the first summer to add, subtract or otherwise modify the second summer output signal with the pilot command input signal (111). Thus, the pilot command input signal (111) is augmented or coupled with the second summer output signal to provide better control of the aircraft while not allowing the flight control computer/avionics control electronic circuitry to directly augment the pilot command input signal.
