Abstract: A ballistic resistant flight deck door assembly for an aircraft is disclosed that also enables pressure equalization within the aircraft in the event of a sudden loss of cabin pressure within the flight deck or cabin. The door assembly includes a door having a plurality of spaced apart panels of ballistic material and a honeycomb support panel. A ventilation area is formed in the door by a plurality of apertures in each of the ballistic panels that are arranged such that no two apertures of the two ballistic panels are perfectly aligned with each other. The blowout panel and ventilation area therefore allows airflow through the door to help equalize pressure within the flight deck in the event of a loss of depressurization of the flight deck without compromising the door's ability to provide ballistic protection for the occupants in the flight deck.

Abstract: A rigid cargo barrier for a cargo airplane includes a lightweight structural bulkhead that is attached to the floor and fuselage shell of the aircraft and a plurality of compact attachments that connect the bulkhead to the floor and fuselage shell of the aircraft. The rigid cargo barrier also includes a restraint system that connects the bulkhead to the aircraft floor and fuselage shell. The restraint system restrains fuselage expansion under crash loads to maintain the bulkhead in place during a crash event and, hence, provide protection to the crew from shifting cargo.
