Developed by the Society of Automotive Engineers (SAE), the SAE AS 50881 standard covers all aspects of electrical wiring systems, from the selection of wiring and wiring devices and optical wiring and termination devices used in aviation vehicles. Aviation vehicles include manned and unmanned aircraft, helicopters, light-air vehicles, missiles and outer capsules. This standard is constantly being revised to include comments received and coordinated.
To facilitate maintenance, each cable and patch cord installed on the aircraft should be marked to associate the cable, its circuit, and gauge size with a wiring diagram.
The basic cable identification code used for all circuits is as follows:
The SAE AS 50881 standard describes the design requirements for the cabling of aviation vehicles. These requirements are generally mandatory, but some are optional and meet the guidance type requirements. states.
The cable types used in aviation vehicles are generally as follows:
In the interpretation of these cable types, the general approach of the standard for the wiring of each new vehicle type is taken into account. This approach includes the safety of personnel, the safety of the vehicle, satisfactory performance and reliability of the vehicle, ease of maintenance, service life and the least cost to the government. The purpose of the SAE AS 50881 standard is to meet the requirements of any designed vehicle. This standard does not apply to cables inside airborne electronic equipment, but to cables connected externally to such equipment.
The requirements in this standard apply to development, prototype, production, rework, and modification wiring on new or in-service vehicles. All wiring inside purely electrical and electronic equipment must comply with applicable equipment specifications rather than this specification.
Our organization also provides aviation vehicle cable testing services within the scope of SAE AS 50881 standard, with its trained and expert staff and advanced technological equipment, among the numerous test, measurement, analysis and evaluation studies it provides for businesses in various sectors.
