The purpose of this document is to give the reader an overview of the document package which makes up AIR825, Introduction to Oxygen Equipment for Aircraft, and a basic overview (see Section 4) of the operational concerns driven by human physiology during altitude exposure. AIR825/1 has been reaffirmed to comply with the SAE five-year review policy.

This report provides information on the design and use of aircraft oxygen systems. It explains the physiological oxygen requirements of the human body in both a normal environment and in an hypoxic environment.It includes an overview of the continuous flow, demand and pressure demand, and liquid oxygen systems. A basic understanding of how each system operates is then specifically addressed in its own titled section.The charts, tables, and schematics provide a specific example of a theoretical oxygen system design and the calculations showing how that system would meet the regulations established by the FAR's. A comprehensive overview of the theoretical oxygen requirements of the human body at altitude is also provided.A detailed list of specifications and standards applicable to aircraft oxygen systems is included. AIR825C is a comprehensive document covering general information on the various types of oxygen equipment and oxygen systems used on aircraft including basic system design information. These requirements and more are covered in greater individual detail by other SAE documents in an AIR825/1 through AIR825/14 document series.

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 Information Report (AIR) provides a general overview of oxygen systems for general aviation use. Included are a brief review of the factors and effects of hypoxia, system descriptions, and mission explanations for system or component selection, and techniques for safe handling of oxygen distribution systems.

This slash document collects general reference material related to gaseous oxygen system flow requirements and sizing calculations. This document will assist oxygen system equipment designers and operators to establish systems and equipment requirements. The document consists of charts, tables, system schematics, system requirements, and sample calculations for system sizing. AIR825/14 has been reaffirmed to comply with the SAE five-year review policy.
