Description / Abstract:
INTRODUCTION:
Liquid oxygen supply systems for breathing for the crew and/or
passengers of transport aircraft require design and installation
considerations, which are detailed herein.
AIR 825, Oxygen Equipment for Aircraft, contains general
information on determination of breathing oxygen requirements and
equipment for the crew and passengers of transport category
aircraft. This document covers the more specific requirements for
either a 70 or 300 psig liquid oxygen system. The standard 70 psig
nominal pressure is recommended for use except in cases of
excessive pressure drop, flow requirements, and some continuous
flow regulators which may require the 300 psig nominal pressure
system.
AS 861, Minimum General Standards for Oxygen Systems and AIR
822, Oxygen Systems for General Aviation Aircraft, also contain
general applicable information.
Note: When Military Specification components are referenced in
this document, it is intended that this be interpreted as a guide
and that components functionally equivalent to these units may be
used.
