Abstract
A system and a method include an emergency exit door for an internal cabin of an aircraft. The emergency exit door includes a lever configured to be engaged to open the emergency exit door. A solenoid is operatively coupled to the lever. The solenoid in a deactivated state is coupled to the lever to lock the lever and prevent the lever from being pulled to open the emergency exit door. The solenoid in an activated state is uncoupled from the lever and allows the lever to be pulled to open the emergency exit door.
