Save design would have the plane controls on a
completely air-gapped
network from the entertainment stuff. I was told that they don?t,
because the captain needs to be able to stop the entertainment system
during an announcement. I could build them a very simple gateway that
transmits UDP packets in one direction only, that would meet this, and
related needs.
This doesn't need a network, just a pair of GPIO pins -- an output
pin on the avionics system, and an input pin on the entertainment system.
