“The issue here is that the fly-by-wire system on Airbus airliners is highly reliant on pitot tube data for proper flight operation”
It is not even the fly by wire per-se. It is the autopilot system and it’s ability to be overridden by pilot input. Pilot control input should always be able to trump what the computer things should happen. It is is a very critical feature that is designed in. I know, I have don’t avionics testing on autopilots. No combination of failures should allow the automatic system to override the pilots intentions. There are ways to design that in, even with a completely fly-by-wire system. It has to do with segregating various control input paths. So it is not JUST that it is fly-by-wire. It is that it is effed up fly-by-wire. I am starting to think it has some very serious design flaws. Flaws that should have NEVER made it past reviews, verification and certification.
