The purpose of this ARP is to provide the guidelines and requirements for analysis, design, and installation of aircraft engine bleed air systems. This ARP discusses design philosophy, system and equipment requirements, installation environment and design considerations for systems within the ATA 100 specification, Chapter 36, Pneumatic. This ATA system/chapter covers equipment used to deliver compressed air from a power source to connecting points for other systems such as air conditioning, pressurization, anti-icing, cross-engine starting, air turbine motors, air driven hydraulic pumps, and other pneumatic demands.
