How will you (the FPGA or the second autopilot) know if the primary autopilot freezes?
We did this with 74LS157 multiplexer chip & AVR for the Outback Challenge 2013 competition. It was a proto-board/wire-wrap implementation (no PCB to share sorry) but another team has made a cleaner version here:
That device is for complying with competition rules, not solving a reliability problem. The extra complexity is dubious safety in my opinion.
Why is your autopilot freezing? Have you ruled out brownout? Can you reproduce it on the bench?
