An aircraft door controller 100 has a receiver 110 which can receive a command 14 to move an aircraft door relative to a door frame, the controller does not store the command when power to move the door is unavailable; such as during ground maintenance, to prevent unexpected opening of the door when power is restored. The power may be hydraulic or electrical and the command may be an electrical signal, which is not latched in memory latch. Preferably, the door controller is part of a door control system 1 having a user control 12 for generating the command. The user control may be a button biased away from a position which would cause generation of the command, still operable, but unresponsive, when power is unavailable; alternatively a lever or a virtual touch screen button may be used. A second user control may be provided; both controls to be operated simultaneously for the command to be generated by the first control, for example. A detector may be provided to detect the door position. The door may be a landing gear bay door or cargo bay door.
