CANaerospace - the Airborne CAN Interface Standard

CANaerospace is an extremely lightweight protocol/data format definition which was designed for the highly reliable communication of microcomputer-based systems in airborne applications via Controller Area Network (CAN).The purpose of this definition is to create a standard for applications requiring an efficient data flow monitoring and easy time-frame synchronisation within redundant systems. The definition is kept widely open to allow implementation of user-defined message types and protocols.

CANaerospace was first released in 1998 and has since then been implemented in numerous airborne applications for aircraft as large as the SOFIA Boeing 747SP. For some flight critical systems of the Ae270 IBIS aircraft, it has been certified by the US Federal Aviation Administration (FAA). CANaerospace is continuously being developed further and has also been published by NASA as the Advanced General Aviation Transport Experiments Databus Standard (AGATE) in 2001. CANaerospace is also the leading interface standard for flight simulator cockpits (Eurofighter, Eurocopter, NH90, Pilatus, and many more) driving flight simulation systems all over the world. Furthermore, CANaerospace serves as communication network in several Experimental, UL and General Aviation avionics systems.

Since 2012, BRP Rotax delivers its 912iS and 915iS aero engines with a redundant CANaerospace data bus interface allowing a smooth plug & play integration of engine data into existing CANaerospace avionic suits. The Rotax engine commonly powers certified light aircraft, homebuilt aircraft, autogyros and military UAVs such as the MQ-1 Predator, IAI Heron and Elbit Hermes.
