Others have commented on here before about how that idea is incorporated into flight control systems.

Here's an example with the Boeing 777 that uses separate architectures:

>The aircraft has triple redundant digital autopilot and flight director designed by Rockwell Collins. The BAE Systems (formerly Marconi Avionics) triple digital primary flight computers provide control limits and commands flight envelope protection. Each of the three primary flight computers contains three different and separate set of 32-bit microprocessors, Motorola, Intel and AMD, to manage the functions of fly-by-wire.

If I remember correctly, that doesn't mean all three autopilots are talking to each other discussing what the best course of action is, it just means that when one fails or is shut off by the pilot that the next auto pilot system in line gets control.

If I also remember correctly, subsequent backup auto pilot systems usually only do the basics, so they can't compare and contrast with the first main auto pilot system on a lot of different actions.

They also write it in Ada to prevent many issues.
