A type of automatic flight control system in which part of the output is fed back into the input to help control the action. For example, if an autopilot senses a wing drop, it sends the signal to the aileron control to correct it. A servo-feedback signal is received by the autopilot, which indicates that a corrective action is being taken. The quantum of error signal is gradually reduced until the wing returns to the level flight and the aileron is neutral. See also feedback (ii).
