    That's how an auto throttle should be. I like it when I can see what the AP is thinking (even if it is a bit confused). Airbus just, you put it a T/O and that's it, and I hate that.

      except that only boeing had a crash that was the fault of an autothrottle

      @anboVIII Actually, Airbus has had well over 2 dozen crashes related to automation: Air France 447, Air France 296, China Air 140 and that's just for starters.

      @@jhmcd2 AFR 447 was mostly pilot error, in the final report nothing was even recomennded to change abput anything for airbus automation and the pilots were called incompetent. AFR 296 was also pilot error, failing to properly brief the area they were flying into. Air China 140 it was airlines fault because they failed to install necessary software update which they deemed "unurgent"

      @@anboVIII Actually, that was found to be false. As with many of BEA's investigations, they quickly look to the reason of least consequence, so pilot error often ends up being the cause, just look at the Concorde crash. They blamed Continental on it, but ignored evidence that clearly stated that the crash was the result of a fix that had been made mandatory all the way back in the 70's that Air France never employed and Airbus, as the maintainer, never equipped. Af447 was the same. They blamed the pilot for the issue, but it wasn't based on any real data as they never recovered the flight data recorder. instead, a private investigation found that the pilot was indeed fighting the auto pilot from causing another pitch down moment. The problem was he left it in the stall, instead of allowing the nose to come down at all as he was in a panic. The evidence has been that several Airbus aircraft, including a recent case with an A350, did the exact same thing, just not as violent or long. Initially French courts stated that both Air France and Airbus were clear of any charges which blocked lawsuites, but about 2 or 3 years ago, they the judge stated that he could not and would not clear them of wrong doing, and said that they were at least partly liable.

      The pilots in all of those accidents were incompetent BECAUSE of the automation. Add Airbus Industrie 129 to the list as well.
      AF447. The pilot believed that if he kept pulling back on the stick that Alpha Protect and Alpha Floor would save them.. not realizing that they had been disabled when the plane went into Alternate Law. Compounding the issue was the lack of tactile feedback between the control sticks. The other pilots had no idea the copilot was doing that until he said so.. upon which they realized immediately what was wrong and formulated a corrective action, but it was too late. AF447 would have never happened to a Boeing aircraft.
      AF296 was the pilot demonstrating Alpha Protect and how the plane couldn’t stall. No pilot of a Boeing aircraft would have tried this because it was suicidal. Of course when the plane got too low Alpha Protect wouldn’t let them climb out of it and the engines took too long to spool up. About the only thing that Airbus did right was save everyone from the initial impact vs a Boeing with likely would have stalled or spun-exactly why a Boeing pilot wouldn’t have done it in the first place (even that crazy 707 pass in Zimbabwe was at a major airport with no obstacles).
      Airbus Industrie 129. Demonstrating an engine failure after takeoff to test the automation. They didn’t check their automation to see that the altitude capture had been cleared which can happen on any aircraft. But their overconfidence got the best of them. The plane immediately started climbing to capture altitude rather than pitch or speed.. and the speed decayed to below 90 knots! Alpha protect.. unlike Boeing flight envelope protection.. only preserves angle of attack, not airspeed. Yeah.. if you don’t exceed the critical angle of attack, you don’t stall.. but with a high body angle and none of your thrust at a few hundred feet (they had to idle the remaining engine to keep from doing a Vmc roll).. your recovery altitude is subterranean. And indeed it was.. Airbus chief test pilot and a whole bunch of other pilots killed because of overconfidence in a still flawed system they won’t change. The 777 or 787 would have never let the plane get 20 knots below minimum control speed (Vmc) like the A330 did.

    Kinda sounds like a Spirit Halloween animatronic.
