Abstract
A dead bolt lock apparatus specifically adapted for use with a flight deck door of an aircraft. The apparatus includes a dead bolt member which can be moved between locked and unlocked positions via a key. A lockout handle is included on the side of the apparatus which faces the flight deck area of the aircraft. The lockout handle is movable rotationally from a first position, wherein it has no affect on the use of the key to unlock the dead bolt, to a second position wherein it prevents the dead bolt from being moved out of a locked position by use of the key. The apparatus thus provides an additional degree of security to occupants of the flight deck by allowing them to prevent unlocking of the apparatus even with the key.
