ReneThis section tracks and compares various aviation-specific CAN-bus protocols. Being open source, support for these protocol can always be added at a later stage if required.

MakerPlane CAN-FIX
Flight Information eXchange Protocol over CAN. Useful document for reference: min / max ranges of parameters etc. I find it too restrictive in some aspects, whereas other aspects have not been addressed at all.
ARINC 825
Very promising; used by Airbus and Boeing. Unfortunately the standard is behind a paywall. There is insufficient open information for implementation...
CANopen
Used for space applications (ESA programs)
CANaerospace
Standardized by the US National Air and Space Administration (NASA) as "AGATE Airplane Avionics Data Bus". Used in several aircraft; primary use in engineering simulators

Please make submissions on the CAN-FiX protocol on the Makerplane website if you need something added or changed. It is an Open Source protocol that can and should be changed by the experimental aircraft community as required. It is only restrictive if you think it can't be adapted or changed.... What specifically do you find restrictive and what bits have not been addressed? Lets add them in!
