Jake Hamby’s Post

Everyone loves to hate on Boeing these days, but Airbus's fly-by-wire sidesticks don't have force feedback and the plane's behavior radically changes when something goes wrong (in this case, iced pitot tube sensors) and the computers go into "alternate law" modes. Under "normal law", the computer won't let the plane stall. Also, if the captain and first officer push in different directions, it averages the two values and you get a "dual input" voice warning unless one of them pushes the takeover button. A cascade of temporary system degradations led to this horrific crash after a sustained stall the crew didn't identify, causing them to dive steeply into the Atlantic Ocean. The cockpit voice recorder and flight data recorder were both found in good condition, enabling investigators to reconstruct the whole nightmare, and for later pilots to be trained to handle failures like this. Airbus had already issued a notification to replace the pitot tubes with more reliable ones, but this plane was scheduled to be upgraded in Paris, the destination it didn't arrive at.
