Variable lower limit collective pitch governor to improve recovery of an aircraft

摘要

A flight control system (202) uses a governor (203) configured to regulate the speed of a rotor in the aircraft (111) through collective pitch control of a rotor blade, and a limiter (205) configured to selectively remove the threshold limit of the governor (203) when the collective pitch control exceeds a threshold limit, so as to permit a pilot full command of the collective above the threshold limit. The threshold limit is selectively removed and phased back in to provide temporary pilot control to "cushion" landing of an aircraft (111) when an engine has failed.
