Abstract
A method for hovering an aircraft having at least one wing and at least one rotary wing and at least one propeller, the aircraft comprising an autopilot system. The method comprises keeping the aircraft hovering, with the autopilot system, in the setpoint position, keeping the aircraft hovering in this way comprising controlling, with the autopilot system, a pitch of blades of the at least one propeller irrespective of the setpoint pitch angle and controlling, with the autopilot system, a pitch of blades of the at least one rotary wing as a function at least of the setpoint pitch angle.
Claims14
A method for hovering an aircraft having at least one wing and at least one rotary wing and at least one propeller, the aircraft comprising an autopilot system controlling a pitch of blades of the at least one rotary wing and a pitch of blades of the at least one propeller during a hovering flight phase in a hovering setpoint position with a controlled setpoint pitch angle, the method comprising a modification phase for modifying the setpoint position, the modification phase comprising generating a movement order with a human-machine control interface,
- wherein the modification phase comprises determining, as a function of the movement order, a setpoint lateral speed and a setpoint angular speed about a yaw axis of the aircraft with the autopilot system, and moving the aircraft, with the autopilot system, with the setpoint pitch angle as a function of the setpoint angular speed and the setpoint lateral speed.
