Abstract: A deployment apparatus for use with an escape slide stowed in a pack within an aircraft and adjacent the sill region of an aircraft door opening is operable to deploy the stowage pack from its position within the aircraft fuselage to a position exterior to the aircraft fuselage upon opening of a door mounted in the door opening. The deployment apparatus includes a deployment arm that is hingedly affixed at a first end thereof to the escape slide stowage pack. A second end of the deployment arm is adjacent the interior surface of the aircraft door when the door is in its closed position. An arming device is pivotally mounted on the interior of the aircraft door and is movable between an armed and an unarmed position. In the unarmed position, the arming device is spaced from the second end of the deployment arm and in the armed position the arming device engages the second end of the deployment arm.
