>>1830641Airbus's control system has envelope protection, which means generally the flight computer will ignore retarded commands, or so the marketing weenies claim. The problem was AF447 had frozen over pitots, iirc, so the AoA system was out of whack, and their software would only sound the AoA alarm from one direction, (approaching critical AoA from below), and would go silent once you exceeded it.
So the idiot copilot would let off the stick, the plane's nose would drop, the alarm would sound, he'd pull back into a stall, and the alarm would cease. Problem solved, right? Not
Add in that there was no direct linkage or display to visually clue the pilot into his co-pilot's derp, and the issue just took too long to get to the essence of.
This is why there is no substitute for actually being 10% smarter than the piece of equipment you're flying.
