Full title and description

Oxygen Equipment for Commercial Transport Aircraft Which Fly Above 45,000 Ft — SAE Information Report AIR847A (reaffirmed edition providing guidance and minimum design criteria for oxygen systems and related equipment on transport-category aircraft operating above 45,000 feet).

Abstract

This information report gives minimum design criteria for oxygen equipment to be used on commercial transport aircraft that operate above 45,000 ft. It covers assumptions, crew and passenger oxygen equipment, cabin attendant provisions, limiting decompression cabin altitude, and includes an appendix with supporting information.

Scope

Provides minimum design criteria and guidance for oxygen equipment intended for commercial transport aircraft that fly above 45,000 feet. The report addresses purpose and assumptions, crew oxygen equipment, limits on decompression cabin altitude, passenger provisions, cabin attendant requirements, and includes an appendix with supplementary material. It is an information report (guidance) rather than a normative certification specification.

Key topics and requirements

• Minimum design criteria for crew oxygen systems (performance and provisioning).
• Requirements/assumptions for limiting decompression cabin altitude to protect occupants.
• Provisioning and delivery of supplemental oxygen for passengers.
• Cabin attendant oxygen equipment and operational considerations.
• Operational assumptions and emergency descent considerations affecting oxygen system design.

Typical use and users

Used by aircraft manufacturers, cabin and life‑support system designers, airline engineering and safety departments, maintenance organizations, and regulatory or certification personnel as guidance for selecting and sizing oxygen equipment for high-altitude transport operations. The report is intended to inform design and operational decisions rather than serve as a regulatory mandate.

Related standards

Related documents include earlier SAE AIR847 (previous edition) and other SAE AIR-series information reports and standards addressing aircraft oxygen systems and cabin pressurization. Users should also cross-reference applicable regulatory requirements from certification authorities and other SAE aerospace standards covering oxygen and emergency systems.
