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.

Abstract: A security system adapted for use on an aircraft to prevent unauthorized access into a cockpit area of the aircraft via a cockpit door. The system includes a keypad accessible by individuals in a cabin area of the aircraft. A logic system is in communication with the keypad and also with a switch disposed inside the cockpit. Occupants of the cockpit, via the switch, have the ability to manually unlock the cockpit door, to deny the request for entry, or to do nothing, in which case the door will be automatically unlocked after the expiration of a predetermined time interval. A pressure sensor in communication with the controller allows the electronic door locking member to be automatically overridden, and the door immediately opened, in the event of a decompression condition occurring in the cockpit.
