Oxygen considerations for flight into high elevation airports

2015-11-30
WIP
ARP6527
The scope of this document is to provide guidance concerning the use of oxygen when flying into and out of high elevation airports. Normally for aircraft operations that fly at high altitude, oxygen requirements involving a decompression are generally easy to understand and follow because of the increased delta between cabin and ambient pressures. This document is intended to address a transition zone where cabin and ambient pressures are closely the same and oxygen usage can be compounded by physiologic subjectivity that often accompanies hypoxia. This transition zone is further diluted by regulations which are based not on science but rather sociological mores often not supported by empirical science. An example of this is reflected by differential regulatory requirements between CFR’s 91, 121 and 135. Operators who fly into these high altitude airports will undoubtedly be required to address the inherent threats and errors associated with this transition zone.

When and How Shall Oxygen be Used on Aircraft”

2015-09-22
WIP
AIR6256
The aim of this document is to provide a comprehensive synopsis of regulations applicable to aircraft oxygen systems. The context of physiological requirements, international regulations, operational requirements and airworthiness standards is shown to understand the role of aircraft oxygen systems and to demonstrate under which circumstances is needed on aircraft. With regards to National Aviation Regulations States are committed to the Convention on International Aviation (Chicago Convention). The majority of states have adopted, with some deviations, FAA and EASA systems including operational and airworthiness requirements. Accordingly the extent of this document is primarily focused on FAA/EASA requirements.

CURRENT
AS8059
This SAE Aerospace Standard (AS) applies to a personal, portable oxygen concentrator (POC) to be supplied and used by a passenger requiring supplemental oxygen therapy while traveling on board civil, commercial, or personal aircraft. It covers a POC during both self-powered battery operation and while powered from an aircraft seat’s electrical power through the use of an accessory adapter. The POC is not intended to be connected to the aircraft’s oxygen systems or to be used by any aircraft personnel in any method of treatment or first aid of the general flying public.

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.

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.
