ABSTRACT:
A system for preventing the automatic or inadvertent opening of an aircraft door or access hatch that has not been closed and locked properly provides an increase in the overall flight safety of aircraft. The system includes a door monitoring system (1), which is connected to at least one of a cabin pressure control arrangement (4), a cabin temperature control arrangement (5), and an air tap system control arrangement (36). The door monitoring system (1) provides a signal indicating if at least one door or access hatch is not properly closed and locked. The controllers (4, 5, 36) receive the door monitor signal at respective inputs and also receive information necessary for determining the current flight configuration of the aircraft from various other aircraft systems, such as a landing gear control arrangement or an engine monitor arrangement. The controllers (4, 5, 36) evaluate the several input signals and provide output signals for controlling at least one of a cabin air venting valve, a cabin air flow control valve, and a tap air shut-off valve.
