This document provides information on provisions for passengers with disabilities on board commercial aircraft. In this context the term "provision of medical oxygen" shall be understood as application of oxygen on board an aircraft not linked to (post) decompression in the sense of Airworthiness Requirements FAR/CS 25 and Operational Regulations of FAR 121/135. Information about available equipment and physiological treatment in clinical practice will be provided in this document. It covers the use of oxygen concentrators according to guidance of FAR Advisory Circular AC120-95.

This report presents, paraphrased in tabular format, an overview of the Federal Aviation Regulations (FAR) for aircraft oxygen systems. It is intended as a ready reference for those considering the use of oxygen in aircraft and those wishing to familiarize themselves with the systems requirements for existing aircraft. This document is not intended to replace the oxygen related FAR but rather to index them in some order. For detailed information, the user is referred to the current issue of the relevant FAR paragraph referenced in this report.

This standard covers oxygen masks and breathing valves used with both panel mounted and mask mounted demand and pressure-demand oxygen regulators. Mask mounted oxygen regulators are covered under other standards, but when the mask mounted regulator incorporates an integral exhalation valve, the performance of this valve shall meet the requirements of this standard.

The scope of this document is related to the particular needs of oxygen equipment with regards to packaging and transportation. The document provides guidance for handling chemical, gaseous and liquid oxygen equipment. It summarizes national and international regulations to be taken into account for transportation on land, sea and air and provides information on classification of hazardous material. The aim of this document is to summarize information on packaging and transportation of oxygen equipment. Statements and references to regulations cited herein are for information only and should not be considered as interpretation of a law. Processes to maintain cleanliness of components and subassemblies during processing and assembly or storage of work-in-progress are outside the scope of this document.

This aerospace standard (AS) defines the requirements of portable protective breathing equipment for use during smoke/fire conditions on board an aircraft.

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.

Determine the required minimum oxygen concentration to be breathed prior to, during, and after a loss of cabin pressurization, and

This Aerospace Information Report provides general information to aircraft designers and engineers, regarding LOX, its properties, its storage and its conversion to gas. Much useful information is included herein for aircraft designers regarding important design considerations for a safe and effective installation to an aircraft. The associated ground support equipment needed to support operations of LOX equipped aircraft is also discussed. It is important to realize that LOX equipped aircraft cannot be supported unless this support infrastructure is also available. A significant part of this document will address the specific advantages, disadvantages and precautions relating to LOX systems. These are important issues that must be considered in deciding which oxygen system to install to the aircraft. Also, many commercial and military aircraft use aeromedical LOX equipment that is mostly portable equipment.

This standard covers both general type and quick-donning type mask assemblies in the following classes: a Class A, oronasal, demand b Class B, oronasal, pressure-demand c Class C, full face, demand d Class D, full face, pressure-demand

This SAE Aerospace Recommended Practice (ARP) will provide general guidelines and procedures for servicing and maintaining oxygen systems. Such methods and procedures may be applied to gaseous, liquid, chemical and portable oxygen systems. These guidelines and recommendations will be provided to engineering and maintenance personnel for airlines, modification centers and third party maintenance contractors, to be used while performing maintenance on oxygen systems and components.

The scope of this document is to provide a guideline for the preparation of a plan for testing of inservice chemical oxygen generators to confirm their design useful life. The test program should also allow determination with a sufficient level of confidence, whether generators are suitable for further use (i.e., life extension, or if the useful life limit has been reached).

This guide is intended to promote safe designs, operations and maintenance on aircraft and ground support oxygen systems. This is also a summary of some work by the ASTM G 4 Committee related to oxygen fire investigations and design concerns to reduce the risk of an oxygen fire. There have been many recent technological advances and additional test data is available for evaluating and controlling combustion hazards in oxygen equipment. Standards that use this new information are rapidly evolving. A guide is needed to assist organizations and persons not completely familiar with this process to provide oxygen systems with minimum risks of combustion. This guide does not necessarily address all the detailed issues and provide all data that will be needed. For a complete analysis, supplemental publications need to be consulted. This guide does discuss the basics of oxygen systems fire hazards. The hazard analysis process is discussed and a simple example to explain this process.

This document presents a glossary of many of the terms that can be found in literature covering issues related to aviation oxygen systems and associated topics. Such a listing can never be all inclusive but the majority of important terms are anticipated to be included for reference.

This AIR provides an overview of several emerging technologies for on board oxygen generation. It complements AIR 825/6, which covers pressure swing adsorption using zeolite molecular sieve beds to concentrate and separate oxygen from atmospheric gases. Topics covered here include use of dense ion conductive ceramics, electrolysis of water, high pressure chemical generation, membrane separations, and use of carbon based molecular seive beds.

This Aerospace Standard (AS5727) will provide the basis for a certification approach and contain the methods or criteria for verification of performance required of Oxygen Dispensing Units for use by cabin occupants in the range of 40,000 to 45,000 ft. cabin altittude. 1.1 Purpose - This AS is intended to identify the performance required of Personal Oxygen Dispensing Units in the range of 40,000 to 45,000 ft.

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.

This ARP covers a procedure to be used in the determination of 0.05 to 0.3 ppm of chlorine in oxygen from any type of generator used for emergency or other life-support systems. The methyl orange method described can be considered as a referee technique. Instrumental analysis is also given in Section 8.
