Scope:

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.
