Aerospace Vehicle Wiring, Lessons Learned
|Publication Date:||1 April 2020|
This SAE Aerospace Information Report (AIR) is limited to the requirements of AS50881 and examines these requirements, providing rationale behind them. AS50881 is only applicable to the aircraft electrical wiring and interconnect system (EWIS). Pods and other devices that can be attached to an aircraft are considered as part of the aircraft equipment design. Its scope does not include wiring inside of airborne electronic equipment, but does apply to wiring externally attached to such equipment. The AS50881 scope does not include attached devices but does include the interface between the pod/equipment and aircraft wiring. 3.3.5 addresses components such as antennas and other similar equipment that were once supplied as Government Furnished Aeronautical/Aerospa
The purpose of this document is to provide information about how each of the requirements of AS50881 can affect performance, safety, reliability, and maintainability attributes and the potential consequences of their omission.
The paragraphs listed in Section 3 are the same titles used in AS50881 revision G Section 3. Section 3 lists the individual EWIS system, process, or performance requirements. Each requirement paragraph from AS50881 is show in green font. Following each AS50881 green requirement paragraph (green font), when applicable, there is a "rationale" paragraph in black font. The rationale following each requirement paragraph in this AIR provides information regarding the EWIS safety, reliability, historical context, and performance implications.
