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.

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.

WIP
AIR6829
The scope of this document is to provide helpful information 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 case where cabin and ambient pressures are closely the same and oxygen usage can be compounded by physiologic subjectivity that often may be accompanied by hypoxia. Operators who fly into these high altitude airports will be required to address in their operational manual the inherent issues associated with this transition zone. This document will provide adequate information to aid operators in checking that their procedures will best fit their safety needs with regards to hypoxia and ensure compliance with regulations.
