This invention relates generally to the field of aircraft technology and systems utilized for protection of aircraft, occupants, and operators thereof from hijackers, terrorists, and other anomalous problems while in flight. More particularly, the present invention relates to a device used in conjunction with walls, floor, and ceiling of a
cockpit's entry / exit passageway for protecting the
cockpit crew from weapons, hostility, decompression, and / or physical intrusions. A light weight
protective shield for the
cockpit of an aircraft (i.e. bullet-proof door) along with a internal locking and release device, none of which is provided by prior art. The
protective shield can absorb repeated blows, provide pressure relief in the event of aircraft decompression,
resist penetration of firearms, knives, and explosive devices, and is compliant with FAA regulations. The
protective shield provides a new level of protection for the
crew of a passenger or cargo
airplane and protects the cockpit of an aircraft from hijacking attempts as well as other anomalous events and is comprised of a light weight weapon-proof protective shield that when closed fits snugly with the flight
deck's adjoining floor, walls, and ceiling. This protective shield
system is intended to readily install inside existing aircraft (e.g. over-night retrofit installation) or be installed into new aircraft as they are assembled.
