AIR5933 provides an overview of contemporary technologies (i.e., sensors) that measure the proportion of oxygen in a gas. The use of these sensors in the aerospace environment, with its special constraints, is discussed and papers/reports with detailed information are summarized and referenced. The sensors are divided into expendable and non-expendable sensors. Expendable sensors are based on electrochemical properties, whereas non-expendable sensors rely on paramagnetic, photo-acoustic, electromagnetic, and laser spectroscopy properties.

Solid chemical oxygen supplies of interest to aircraft operations are "chlorate candles" and potassium superoxide (KO2). Chlorate candles are used in passenger oxygen supply units and other emergency oxygen systems, such as submarines and escape devices. Potassium superoxide is not used in aircraft operations but is used in closed-cycle breathing apparatus. Characteristics and applications of both are discussed, with emphasis on chlorate candles.

This Aerospace Information Report (AIR) indicates those dimensions, deemed critical by the manufacturer to assure proper mating of disconnect hose fittings. The dimensions are critical, but not necessarily complete, in defining these fittings since there are other criteria which must also be met.

This AIR indicates those dimensions, deemed critical by the manufacturer, which are required to be adhered to so that proper mating of the disconnect hose fitting with the correct disconnect be accomplished. The dimensions are critical, but not necessarily complete, in defining these fittings since there are other criteria which must also be met.

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.

The purpose of this document is to give the reader an overview of the document package which makes up AIR825, Introduction to Oxygen Equipment for Aircraft, and a basic overview (see Section 4) of the operational concerns driven by human physiology during altitude exposure.

The information provided in AIR825/6 applies to On Board Oxygen Generating Systems (OBOGS) - Molecular Sieve, that utilize the ability of molecular sieve materials by using Pressure Swing Adsorption Process (PSA) to separate and concentrate oxygen in the product gas from the surrounding air, respectively air provided by any compressor or by the aircraft engine (so called: Bleed Air), and to provide this oxygen enriched air or product gas as supplemental oxygen for breathing gas supply of crew and passengers onboard aircraft. The distribution system and the provided oxygen concentration have to fulfill the respective airworthiness regulations. Equipment using this technology is to provide supplemental oxygen for breathing gas supply of crew and passengers onboard aircraft, the suitable breathing gas oxygen partial pressure or oxygen concentration requirements are specified in AIR825/2 and the oxygen purity requirements in AS8010.

This standard defines the minimum requirement for the design, construction and performance of continuous flow oxygen masks for crew and passengers of general aviation civil aircraft.

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 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.
