That sounds like a UI issue. Like, it shouldn't be too hard to put a blinkenlight on the control that indicates it's under autopilot control (or the absence indicates it isn't).
The actual report states that there was a repeated audio cue that this was the case.
There was also a stall warning that shutoff when the pilot pulled up because it no longer had reliable info, the pilot assumed pulling up was somehow stopping a stall
Under which circumstance does pulling up stop a stall, exactly?
It doesn't but the alarm shut off when the pilot pulled up causing confusion. He continued to increase angle of attack the entire time
Wasn't there also the problem with other pilot pushing down in panic, rudder being so enclosed that nobody noticed, and the fact that plane averaged the two inputs?
