Abstract
A cockpit door bodycan be opened toward a cockpit in a direction shown by arrow Rby a crew inside a cockpitby manipulating a knob on a first hinge deviceWhen rapid decompression occurs in the cockpit, a mechanical pressure-sensitive device of the first hinge deviceoperates to release a bolt from a catch. By the difference in pressure between the cabin and the cockpit, the door bodyopens in the direction of arrow Rto thereby reduce pressure difference. When rapid decompression occurs in cabina second latch devicedetects this pressure difference and operates mechanically to rotate a link leverto release a stopperfrom a catchFlapsandare opened toward cabinin the direction of arrow Rby the difference in pressure between the cockpit and cabin to thereby reduce pressure difference.
