The chronology below clearly shows that the crash has nothing to do with the pitots tubes, nor the stall warning, nor the sidestick
What rubbish. If the technology can't correct for pilot error then it's rubbish technology. That's what FBW is all about. What part of the word "protection" in "flight envelope protections" doesn't you understand. The software is to protect the pilot from screwing up. It didn't. It failed.
People keep talking about pilot error as if that's the conclusion of the matter.
Pilot error is just the beginning. Every single major advance in flight safety over the last hundred years has happened because "pilot error" was not an acceptable answer. The fact that the pilots in AF447 screwed up is as obvious as it is irrelevant. The pilot is just one cog in the system. If the system cannot compensate for errors in the system then it isn't a robust system.
