This specification provides the overview of aircraft data networks installed in air-transport aircraft, tutorial information for adaptation of commercial network standards to air-transport aircraft, and terminology used to describe aircraft data networks. This specification explains the dependency of Aircraft Data Network (ADN) standards on network standards developed by the Internet community, IEEE, and ISO. The classes, Compliant Networks and Profiled Networks, used to characterize aircraft networks are introduced.
This SAE Information Report provides information on certain fuels that are being used or have been suggested as alternatives to motor gasoline (SAE J312) or automotive diesel fuel (SAE J313) for use in spark-ignition or compression-ignition engines. Some of these fuels are derived from petroleum while others are from nonpetroleum sources.
This paper describes a recommended practice and procedure for the correlation of test cells that are used for the performance testing of APU (auxiliary power unit) engines. Test cell correlation is performed to determine the effect of any given test cell enclosure and equipment on the performance of an engine relative to the baseline performance of that engine. The baseline performance is generally determined at the OEM designated test facility.
This paper describes a recommended practice and procedure for the correlation of test cells that are used for the performance testing of APU (auxiliary power unit) engines. Test cell correlation is performed to determine the effect of any given test cell enclosure and equipment on the performance of an engine relative to the baseline performance of that engine. The baseline performance is generally determined at the original equipment manufacturer (OEM) designated test facility. Although no original equipment manufacturer (OEM) documents are actually referenced, the experience and knowledge of several OEMs contributed to the development of this document. Each engine Manufacturer has their own practices relating to correlation and they will be used by those OEMs for the purpose of establishing certified test facilities.
This set of criteria is to be utilized by accredited Certification Bodies (CBs) to establish compliance, and grant certification to AS5553, Aerospace Standard; Counterfeit Electronic Parts; Avoidance, Detection, Mitigation, and Disposition.
