Oxygen supply and distribution system for a passenger aircraft

摘要

Aircraft passengers who require a therapeutic oxygen supply independently of the prevailing cabin pressure, as distinguished from an emergency oxygen supply that depends on an inadequate cabin pressure, can breath therapeutic oxygen and/or emergency oxygen depending on the situation, through the same therapeutic oxygen masks. For this purpose a control accessible to the crew is used to connect a therapeutic oxygen supply to the emergency oxygen distribution system of the aircraft, whereby the source of oxygen is used either partially for therapeutic purposes or fully for emergency purposes.
