A CONTROL SYSTEM FOR CONTROLLING A LANDING GEAR DRIVE SYSTEM

The invention provides a control system 200 for controlling a landing gear drive system 72 for driving rotation of an aircraft wheel, comprising a control panel 40 with a controller 20 having a forward motion setting 23, 28, 24 30 and a zero speed setting 27, a control unit 60 for receiving a control input 41 from the controller, and for providing a torque command 71, 81 to be applied to the wheel, and a speed sensor 50 for sensing an aircraft taxi speed and for providing an indication of the aircraft taxi speed 51 to the control unit, wherein, when the controller is moved from the forward motion setting to the zero speed setting, the control unit provides a torque command 71 to the drive system to provide zero forwards driving torque to the wheel, and a braking command 81 to apply a braking torque to the wheel. The invention provides other control systems, an aircraft, methods of controlling an aircraft landing gear drive system and a control panel.
