Abstract
An aircraft electrical actuator arrangement includes a plurality of actuators and a master power converter to convert power from the electrical power distribution network for supply to each actuator. The actuators include an environmental control system actuator, an aileron actuator, a flap actuator, a slat actuator, a landing gear actuator, a thrust reverser actuator, a brake actuator and a taxiing actuator. A controller is coupled to the master power converter and is arranged to allow the supply of power from the master power converter to the environmental control system actuator during a first mode of operation of the aircraft. The controller is arranged to allow the supply of electrical power from the master power converter to at least one of the aileron, the flap, the slat, the landing gear, the thrust reverser, the brake actuator or the taxiing actuator during a second mode of operation of the aircraft.
