Flight deck security pocket door decompression venting and crew escape system

A locking mechanism for a door panel to be positioned within and out of blocking relationship with an opening defined by a wall, comprising:

• a deadbolt having a curved configuration with the deadbolt rotatably connected to the wall;
• and
• a locking bracket connected to the door panel, wherein:
• the locking bracket extends from the door panel in an angular direction with respect to a plane of the door panel to a distal end of the locking bracket positioned spaced apart from the door panel;
• and
• with the door panel in a closed position relative to the opening and the deadbolt in a first position, the locking bracket is positioned through the curved configuration of the deadbolt;
• wherein:
• the deadbolt is in blocking relationship with the locking bracket to block the door panel from moving in a direction along the plane of the door panel;
• and
• the deadbolt and the locking bracket are not in blocking relationship in a direction along the locking bracket such that with the door panel hinged to a first rail track which extends along a first end portion of the opening and to a second rail track which extends along a second end portion of the opening, the door panel is permitted to swing away from the wall in the direction along the locking bracket;
• and
• with the door panel in the closed position relative to the opening and the deadbolt in a second position, the deadbolt is not in blocking relationship with the locking bracket to permit the door panel to move in the direction along the plane of the door panel;
• at least one hinge blocking assembly including a first bracket disposed in a fixed position and a second bracket coupled to the first bracket, and the second bracket is movable relative to the first bracket about a fixed axis of rotation;
• and
• a blocking plate overlies at least a portion of the door panel when the door panel is in the closed position and the second bracket is in a first position.
