Fuel Versus Oxygen: Evaluations and Considerations
AIR5648
Specific federal aviation regulations (Titled 14 of the United States Code of Federal Regulations, or 14 CFR) define oxygen system requirements for an in-flight decompression incident. This AIR addresses the operational oxygen system requirements for a decompression incident that may occur at any point during a long-range flight, with an emphasis for a decompression at the equal time point (ETP). This AIR identifies fuel and oxygen management contingencies, and presents possible solutions for the efficient, safe, and optimum fuel/oxygen flight continuation. Oxygen management is a concern to all aircraft, such as single engine types that fly above 10 000 feet and use supplemental oxygen. This document provides a method which can help guide users in developing an oxygen solution for their aircraft.
Rationale: New technologies (iPad) is making it easier to access and manipulate data where other metrics aside from liters or PSI can be used to measure and manage the aircraft oxygen system. This will not change or alter the existing document but will add additional metrics to expand the users ability to manage and convert PSI into other more usable and understandable metrics for the end user.
