Abstract: A control system and method of controlling a propeller aircraft engine during takeoff limits the amount of engine power developed at the very beginning of the takeoff in order to maximize thrust and minimize rollout distances. The control system limits the amount of power developed by the engine, even in the face of a nominal demand by the pilot for maximum engine power. Instead, the control system provides something significantly less than full power at the beginning of takeoff and gradually increases the power developed by the engine to full power as the airspeed increases. This gradual increase from partial engine power toward full power helps prevent stalling of the propeller, thereby maximizing the effectiveness of the propeller and engine in assisting the aircraft to takeoff quickly. The control system is particularly helpful for taking off from high-altitude runways.
