An aircraft door mechanism includes a solenoid connected to a support assembly. The solenoid displaces the latch pin between a solenoid energized and a solenoid de-energized position. A catch assembly rotatably connected to the support assembly is positioned to engage a 3½ degree or less taper portion of the latch pin in the solenoid energized position. When the latch pin moves to the solenoid de-energized position, a latch bolt supported by the door rotates the catch assembly. The latch bolt includes a distal bulbous end which multiplies the force applied to the door to rotate the catch assembly. If the latch pin is extended, a substantially greater force is required to force the latch pin to the solenoid de-energized position owing to the reduced taper of the latch pin. Authorized door entry is therefore easier and unauthorized door entry is made more difficult. |

In an apparatus for warning of differential pressure during the opening of a pressure-loaded closure device (1) of an opening in the aircraft fuselage by means of an opening mechanism (4; 100; 105), the invention exists in that an air guide passage is provided from the side with higher pressure (passenger cabin P) to the side with lower pressure (outside environment A). The air guide passage is closeable by a valve (5; 209), whereby it is controllable with a control lever (4; 208) placed in operative connection with the door opening mechanism, and produces an acoustic signal upon opening of the valve (5; 209) and an existing differential pressure. With such a warning apparatus, a differential pressure indication independent of a supply system is provided and serves as a warning signal for the operator of an aircraft door. Thereby, the differential pressure indication is directly coupled to the action of the operator. Moreover, false alarms are excluded and the warning apparatus achieves a very high reliability. |

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. |
