Lately I've been wondering if it's possible to interface an everyday computer with the ARINC buses (either 429 or AFDX).
This would be very useful for simulation, testing and prototyping purposes. For example, we could write a computer program that sends ARINC labels to the bus and see how the avionic systems react to it.
But I think that the greatest challenge would be in the physical layer.
The image on the left shows some connectors that we can typically find in everyday computers. The image on the right shows the connectors that we can find in the front panel of an avionic system.
At first glance making such a connection does not look straightforward.
Nevertheless I've done some research and I have found devices which seem capable of interfacing a computer with the ARINC bus via the USB port:
These pocket-sized USB adapters are the easy and portable way to interface your computer to ARINC 429 and ARINC 717 Avionics databuses.
So connecting a computer and avionics is possible in theory. Still, I don't see how I would be able to connect this USB-ARINC adapter to the avionics box, since the connectors are different.
So there must likely be an access point somewhere in the avionics where this adapter can be connected.
This is all I could find.
- Is it possible to communicate an everyday computer with the ARINC bus?
- If so, what is the access point where we would connect the wire?
- Would there be any other challenges I didn't take into account?
