ABSTRACT:
A system for providing an emergency exit in a wall of an aircraft includes a pyrotechnic device disposed against the wall, and capable of cutting a desired opening in the wall, an igniter for the pyrotechnic device, a controller for the igniter, and a manometric safety device which receives the pressures inside and outside the aircraft and inhibits the action of the igniter when the difference between the pressures inside and outside the aircraft is greater than a predetermined value.
