This SAE Aerospace Information Report provides a general discussion on gaseous breathing oxygen and oxygen equipment for use on commercial aircraft. Other types of oxygen systems are mentioned to assist in this discussion. For detailed information on systems other than gaseous, refer to the appropriate section of AIR825. The content of the SAE Aerospace Information Report is updated to reflect the latest oxygen system design practice realized on current aircraft.References to actual standards (e.g., SAE, ISO) are added. Extensive revision of the chapters fire risks, design precautions and the use of check valves are included. Editorial changes are made in addition.

This SAE Aerospace Recommended Practice (ARP) provides design, operation, construction, test and installation recommendations for equipment that automatically presents supplemental oxygen masks to cabin occupants in the event of loss of cabin pressure. It specifically covers automatic presentation for transport category aircraft that operate above 30 000 ft (9144 m) altitude. It also provides guidance for similar equipment used in non-transport category aircraft, or aircraft operated below 30 000 ft (9144 m) altitude. ARP4287A has been reaffirmed to comply with the SAE Five-Year Review policy.

This SAE Aerospace Recommended Practice (ARP) covers procedures or methods to be used for fabricating, handling, testing, and installation of oxygen lines in an aircraft oxygen system. This report, in conjunction with the other referenced SAE documents, provides a comprehensive guide for the development and test of aircraft oxygen system lines. This document has been revised to reflect current industry recommended practices regarding the fabrication, installation, and test of aircraft oxygen system lines. The SAE A-10 committee has revised this document to include industry recommendations for repair and electrical bonding of aircraft oxygen system lines.
