A method for position hold override control of an aircraft includes determining, by a processor, that a position hold mode is enabled to hold the aircraft at a substantially fixed position with respect to a target. The processor receives a control input indicative of a commanded change in acceleration of the aircraft as an override of the position hold mode. The processor determines an acceleration command based on the commanded change in acceleration. The acceleration command is adjusted as an adjusted acceleration command responsive to a non-linear scheduled translational rate command based on feedback of a commanded velocity of the aircraft. An update to the commanded velocity of the aircraft is generated based on the adjusted acceleration command.

An assembly for manual control of an HSTA for controlling the position of a moveable surface, the assembly comprising a user-operated manual control element (1) e.g. a trim wheel in the cockpit, a first motor and a first resolver connected to the manual control element and a second motor and a second resolver arranged to communicate with the first motor and the first resolver and to cause corresponding movement of the actuator, in use.

A flight control computer (FCC) may implement automatic rotor tilt control by gathering or receiving, as inputs, airspeed or a commanded airspeed for the aircraft, acceleration or a commanded acceleration for the aircraft, pitch attitude of the aircraft and pilot pitch bias commands for the aircraft, a rotor tilt angle, and/or the like. The FCC calculates, from the airspeed, the commanded airspeed, the acceleration, the commanded acceleration, the pitch attitude, the pilot pitch bias commands, and/or the like, a commanded rotor tilt angle for the aircraft. From the aircraft rotor tilt angle and the commanded rotor tilt angle, the FCC calculates a rotor tilt angle error for the aircraft, and from the rotor tilt angle error, calculates a rotor tilt rate command for the aircraft. The FCC outputs the resulting rotor tilt rate command to (an) aircraft flight control element actuator(s) to tilt the aircraft rotor.

In some embodiments, a control manager is disposed between the rotor system and the flight control inceptor. The control manager is configured to receive control commands wirelessly from a ground control station, translate the control commands into one or more axes associated with the flight control inceptor, and transmit the translated control commands to the rotor system in place of the instructions received from the pilot via the flight control inceptor.

Aircraft and associated methods, apparatus, system and storage devices for automatically positioning of lift control devices such as high lift devices including slats and flaps so an aircraft equipped with this technology will not need to count on the crew to command the lift control devices.

An embodiment rotorcraft includes a rotor system including a plurality of blades; a control assembly operable to receive commands from a pilot; a flight control system (FCS), the flight control system operable to control flight of the rotorcraft by changing an operating condition of the rotor system; and a flight management system (FMS) in signal communication with the control assembly and the FCS. The FMS is operable to receive a target location and a plurality of approach parameters from the control assembly; generate a plurality waypoints between a current location of the rotorcraft and a missed approach point (MAP) based on the target location and the plurality of approach parameters; receive a command to engage in an approach maneuver from the control assembly; and in response to the command to engage in the approach maneuver, instruct the FCS to fly to the MAP.

An aircrew automation system relates to the field of flight control systems, methods, and apparatuses; even more particularly, to a system, method, and apparatus for providing aircraft state monitoring and/or an automated aircrew employing a robotic arm with integrated imaging and force sensing modalities.
