ABSTRACT:
Automatic flight control apparatus, preferably for use in a helicopter, comprises a parallel connected servosystem which allows the apparatus to discern manual input forces and to respond naturally to them. The manual forces are sensed internal the parallel servosystem by monitoring the corrective error drive signal to the parallel servomotor. A signal indicative of excess manual force is used to develop other signals, one of which aids in temporarily defeating the command signal generated by the autopilot in trying to do its job, and another of which temporarily contributes positive feedback within the parallel servosystem so as to cause the servomotor to aid the pilot's manual input force. Another preferred embodiment includes a series connected servosystem.
