There is disclosed a system and technique which enables an aircraft (helicopter or VTOL) to be more easily controlled for maintaining precise position or velocity in a hover condition. The system includes operational logic and decision making circuitry which reduces pilot workload by sensing pilot intent based upon the control stick movement and mode selection of the aircraft. The system will automatically hold a given hover position, automatically hold a given hover velocity (ground speed), or allow the aircraft to be manually maneuvered to a new desired hover position or velocity. The system also enables the aircraft to either hold a new velocity or return to a previous velocity. This is all controlled through the automatic flight control system and by sensing the force or displacement of a pilot\s control stick in the aircraft. Upon release of the manual force applied by the pilot to the control stick, the stick returns to a neutral position and the control logic recognizes pilot intent to maintain a given hover velocity or position.

An aircraft control system comprising: control means movable between a neutral position and a control position for providing an aircraft pilotage control signal in said control position; means for providing a position signal representing aircraft position; means for providing a velocity signal representing aircraft velocity; means responsive to said position signal and a reference position signal for generating a position control signal for maintaining aircraft position; means responsive to said velocity signal and a reference velocity signal established independent of control means displacement from a neutral position for providing a velocity control signal for maintaining aircraft velocity; means responsive to aircraft velocity for selectively providing one of said position control signal and said velocity control signal as a selected signal; and means for controlling said aircraft in response to said aircraft pilotage control signal when said control means is in a control position and for controlling said aircraft in response to said selected signal when said control means is in said neutral position.
