Avionic Systems Standardisation Committee

This guide was commissioned by MoD through the Avionic Systems Standardisation Committee (ASSC). It compares the Def Stan 00-18 series of interface standards with several Electronic Industries Association (EIA) civil data transmission standards and two civil avionics data transmission standards developed by Air Radio Incorporated (ARINC) under the auspices of the Airlines Electrical Engineering Committee (AEEC), ARINC 429 and ARINC 629. The guide also includes a review of Time Triggered Protocol (TTP), Adaptive Standard PredictivE Network (ASPENTM), Universal Serial Bus (USB), IEEE 1394 Standard for a high performance serial backplane bus, and the Controller Area Network (CAN) standard which originated in the automobile industry and WorldFIP Fieldbus which originated in the industrial & process control industry. The large difference in component cost between Def Stan 00-18 and EIA standards has been seen as an opportunity to save money by using these particular civil standards in military avionics systems. A suggestion in this vein has been made with particular reference to Def Stan 00-18 (Part 3), the Simplex and Half Duplex Serial Interface. This text is a careful technical summary of the issues involved so that there is a prepared position available.
