ABSTRACT:
A precision approach control system designed to control the approach of an aircraft during landing to provide a more stable and easier mode of landing during critical landing situations, such as during the landing of an aircraft on an aircraft carrier. During operation, when the aircraft is subjected to vertical or horizontal winds or wind shear, the system controls the aircraft to maintain the inertial flight path angle constant which essentially defines operation in the precision approach control mode. In one disclosed embodiment, the precision approach control system changes the controller in the cockpit that is normally the pitch rate command stick controller during a Power Assist landing into a flight path angle rate controller. The autothrottle system for the aircraft is utilized to maintain the aircraft at a predetermined angle of attack during landing in the precision approach mode.
