Abstract
A door strike apparatus for enabling opening of a door in the event of a decompression condition experienced within a flight deck area includes a housing supported adjacent the door and a strike arm movable between a locked state restricting rotation of the door and an unlocked state permitting rotation of the door. A solenoid having a lock member retracted from the strike arm when the strike arm is in the unlocked state and engaged with the strike arm when the strike arm is in the locked state. The solenoid is responsive to the decompression condition and selectively toggles the lock member out of engagement with the strike arm to permit automatic unlocking of the strike arm and opening of the door under the decompression condition and into engagement with the strike arm to permit selective locking of the door when the decompression condition is absent.
