A system 100 for moving an aircraft door 10 from an open position towards a closed position. The system comprises an aircraft door actuator 110 for moving the aircraft door from an open position towards a closed position with an input 105 for receiving primary power from a primary power supply 20. The primary power is able to move the aircraft door from the open position towards the closed position. The system further incorporates a secondary power supply 120 for powering the aircraft door actuator to cause the aircraft door actuator to move the aircraft door from the open position towards the closed position. There is additionally a controller 130 configured to cause the secondary power supply to power the aircraft door actuator to cause the aircraft door actuator to move the aircraft door from the open position towards the closed position, on the basis of a determination that insufficient primary power is available from the primary power supply. The secondary power supply may be a pump for pumping hydraulic fluid or a pressure accumulator for storing hydraulic fluid. Also disclosed are a method of moving an aircraft door from an open position towards a closed position and an aircraft.
