A security pocket door traverses within a security bulkhead wall that
defines a pocket, within which the pocket door traverses, and a through
passage to permit people, carts and luggage to pass. The pocket door has
an upper door track mechanism and a lower door track mechanism that
engages a corresponding upper and lower track mechanism of the bulkhead
and floor, respectively. The bulkhead door locks with at least one
solenoid with a locking pin that engages a hole in a tab of the pocket
door. The locking pin creates a magnetic field with a magnet located in
the tab to send a signal to the flight deck in order to indicate a closed
and locked or an unlocked pocket door condition. When the pocket door is
in its closed position, the door perimeter overlaps the bulkhead on at
least three sides of the door and also overlaps with the floor.
