Abstract
An improved apparatus and method are provided for warning a pilot of life-support system failures wherein the life-support system includes at least a pressurization system and a breathing gas supply system. The breathing gas supply system which is contemplated in the presently preferred embodiment of the invention is the type wherein breathing gas may be supplied to the pilot from a plurality of on-board sources. The apparatus which is the subject of the present invention is responsive to both the operating conditions of the pressurization system and the breathing gas supply system to provide minimum warnings to the pilot thereby to improve the effectiveness of the warnings. The apparatus includes a plurality of indicators which, during normal operation, are substantially invisible to the pilot. The indicators are illuminated under certain variable conditions of the pressurization system and the breathing gas supply system. Further, a portion of the indicators may be illuminated in first and second formats whereby each format is indicative of a different priority emergency.
