This specification covers general requirements for the installation of sound and thermal insulation in aircraft.

This specification covers general requirements for the installation of sound and thermal insulation in aircraft.

This publication formalizes the applicable design concepts considered acceptable for "draw-through" cooling of electronic (avionic) equipment installed in subsonic and supersonic commercial jet transports. Methods other than draw-through cooling are covered in AIR 728A for high Mach number aircraft.

This Aerospace Recommended Practice (ARP) defines tests to be performed on hydraulically, electrically, pneumatically, and mechanically actuated air valves. They may be further defined as those valves that function in response to externally applied forces or in response to variations in upstream and/or downstream duct air conditions in order to maintain a calibrated duct air condition (e.g., air flow, air pressure, air temperature, air pressure ratio, or air shutoff).

This SAE Aerospace Information Report (AIR) outlines concepts for the design and use of fault isolation equipment that have general application. The specific focus is on fault isolation of environmental control systems (ECS) in commercial transports. Presented are general fault isolation purposes, design principles, and demonstration of compliance criteria. These are followed by three design examples to aid in understanding the design principles. Future trends in built-in-test-equipment (BITE) design are discussed, some of which represent concepts already being implemented on new equipment.
