Doors and Slides Management System
Swivel Actuator, Flight Lock Actuator, De-Arrest Actuator
The electric door actuation system on the A380 replaces conventional manual door opening mechanisms. The system includes three actuators; the Swivel Actuator which opens and closes the aircraft door; the De-Arrest Actuator which secures the door in the open position and the Flight Lock Actuator that ensures the door remains locked during flight. To safeguard the integrity of the system in critical situations redundant windings are integrated in the Swivel Actuator.
