Abstract
An airplane with an over-compressed cabin and autopilot and comprising pressure-sensitive means exposed to pressure within the over-compressed cabin, a normally ineffective mechanism arranged to be automatically operated by pressure-sensitive means in response to reduction to a certain pressure limit in the overcompressed cockpit at a height above the critical height to govern the autopilot so that the aircraft is kept in flight at an essentially constant Mach index not exceeding the critical Mach index which automatically acts when the airplane has descended to a critical or approximately critical height to modify the action of the aforementioned mechanism so that from this moment the airplane remains in flight at an equivalent constant speed in relation to air that does not exceed the equivalent critical speed with respect to air and means that automatically operate when the aircraft has descended at a safety height to remove the control of the aforementioned autopilot mechanism.
