Fuel Versus Oxygen: Evaluations and Considerations

2013-04-04
CURRENT
AIR5648A
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.

HIGH PRESSURE OXYGEN SYSTEM FILLER VALVE

1971-07-30
HISTORICAL
AS1225
This AS covers oxygen filler valves for use in aircraft to ensure safe servicing of high pressure oxygen system cylinders. The intent is that the valve shall automatically control the rate of fill such that the temperature rise in the oxygen system caused by compression heating of the gas will be within acceptable limits. In addition, the valve shall have a pressure sensitive closing valve to automatically control the final pressure for a correct amount of oxygen in the system cylinder. The pressure closing level may be manually selected by means of adjustment dials on the valve.

MINIMUM STANDARDS FOR VALVE, HIGH PRESSURE OXYGEN, CYLINDER SHUT OFF, MANUALLY OPERATED

1968-12-01
HISTORICAL
AS1066
This standard covers all types of manually operated high pressure oxygen, cylinder shut off valves for use in commercial type aircraft. It is intended that the valve shall be attached to a pressure cylinder storing oxygen under pressure of 1800 to 2100 psig at 70 F. Upon opening the valve, oxygen will be permitted to discharge from the storage cylinder to the valve outlet and thence to other components of the oxygen system. It shall also be possible to recharge the cylinder through the valve.

MINIMUM STANDARDS FOR VALVE, HIGH PRESSURE OXYGEN, LINE SHUT OFF, MANUALLY OPERATED

1971-07-01
HISTORICAL
AS1214
This standard covers all types of manually operated high pressure oxygen line shut off valves utilizing either metallic or nonmetallic valve seats for use in general and commercial type aircraft. It is intended that the line valve should be installed in a position accessible in flight, when the cylinder mounted oxygen valves are not. The line shutoff valve may also be used optionally in large systems as a maintenance aid where only a portion of the system need be opened up and purged after repair or replacement of one or more parts.

AS1066B
This standard covers all types of manually operated high pressure oxygen, cylinder shut off valves for use in commercial aircraft. It is intended that the valve shall be attached to a pressure cylinder storing oxygen under a nominal pressure of 12.76 MPa (1850 psig) at 21 °C (70 °F). Upon opening the valve, oxygen will be permitted to discharge from the storage cylinder to the valve outlet and to other downstream components of the oxygen system. It shall also be possible to recharge the cylinder through the valve.

HISTORICAL
ARP5021
This document provides guidance for oxygen cylinder installation on commercial aircraft based on rules and methods practiced in aerospace industry and as far as applicable in other associations. It covers considerations to be taken for oxygen systems from beginning of project phase up to production, maintenance, and servicing. The document is focused on requirements regarding DOT approved oxygen cylinders. However, its basic rules may also be applicable to new development pertaining to use of such equipment in an oxygen environment. For information regarding oxygen cylinders itself, reference should be made to AIR825/12 also.

Oxygen System Fill/Check Valve

1997-12-01
CURRENT
AS1225A
This SAE Aerospace Standard (AS) defines minimum standards of design, construction, and performance for two types of permanently installed, high pressure 12,800 kPa (1850 psig) and 13,800 kPa (2000 psig) oxygen system cylinder fill valves used in commercial aircraft. Refer to Purchaser's Specification for Requirements which are beyond the scope or level of detail provided in this document. One valve has an adjustable pressure sensitive closing valve to automatically control the final pressure for a correct amount of oxygen in the system. The second valve incorporates an automatic shutoff feature designed to limit system overpressurization in the event maintenance personnel do not stop system filling at the correct pressure. The intent of the fill valves is to control the rate of fill to limit the rise in temperature caused by compression heating to acceptable values, prevent oxygen back flow and prevent the ingestion of foreign matter that could cause contamination of the system.
