A cockpit access security system controls changes to a record of personnel authorized to access the cockpit by reference to the state of the aircraft as determined by a plurality of on-board sensors indicating the state of particular aircraft subsystems.

The present disclosure provides a door latch assembly including (a) a locking pin movable from an extended position where the locking pin is positioned in an aperture of a driver, to a retracted position where the locking pin is configured to be removed from the aperture of the driver, (b) a solenoid including a solenoid plunger having a first end coupled to the locking pin and a second end coupled to a shaft, (c) a lever arm having a first end engaging the shaft, and (d) a switch including an actuator button in contact with the lever arm, wherein when the solenoid is actuated the solenoid plunger moves to retract the locking pin from the aperture and causes the shaft to displace the lever arm and the actuator button to activate the switch.

There is provided a system for securing a cockpit from a cabin. A lavatory door has a locking mechanism provided thereon. A latching mechanism is provided on an adjacent structure across an aisle from the lavatory. The locking mechanism is compatible with the latching mechanism to secure the lavatory door in an open position, thereby forming a secure area for entering from the cockpit.

An information projection and control system for projecting information onto a projection area provided by a vehicle door, comprising at least one control unit that generates information, for projection onto the projection area; at least one projection device that projects the generated information onto the projection area; and at least one movement sensor that detects movements in a sensing area associated with the projection area, wherein the at least one control unit is adapted to control generation of the generated information on the basis of the detected movements.

A door latch assembly, includes: a catch support assembly, the catch support assembly including a strike body having a pin receiving aperture therein; a catch arm assembly rotatably mounted to the catch support assembly; a latch pin positioned in the pin receiving aperture and movable between a retracted position and an extended position, the latch pin protruding above the strike body in the extended position to impede rotational movement of the catch arm assembly; and a first roller mounted to the catch arm assembly and configured to engage a first side of the latch pin in the extended position; and a second roller mounted to the catch support assembly and configured to engage a second side of the latch pin in the extended position. The latch pin includes a material having a hardness of 60 Rockwell C or more, the first roller includes a material having a hardness of 33 Rockwell C or less, and the second roller includes a material having a hardness of 60 Rockwell C or more.

A cockpit internal anti-sabotage system (CIASS) without compromising the cockpit security and the present anti-hijacking procedure and protocol, wherein a single cockpit crew alone in the cockpit cannot deny bonafide entry of other cockpit crew or cabin crew in an attempt to commit suicide or sabotage the aircraft, the system comprises a manual door lock system and an automated door lock system wherein both the systems comprising a mechanical system or a non-mechanical system or combination of both.
