A system of flying controls in which the force needed to move the surface, although partly provided by the pilot's effort, is supplemented by electrical, hydraulic, or pneumatic means. In a power-assisted flight controls system (FCS) failure, the pilot will have some difficulty in controlling the aircraft. This was the system used in aircraft when power controls were introduced, and it is no longer in use. Sometimes referred to as power-boosted controls.
