The left alpha vane was being interpreted as almost exactly twenty degrees higher than the right.

Is that because the plane was in a banking maneuver at the time maybe? I dont know anything about planes but I heard that when you're turning the two sensors will disagree by some amount




I think it's been disclosed that in Lion Air the sensors were twenty degrees apart even when sitting on the runway before the flight. It is shocking that nothing checked for disagreement or communicated it to the pilots.

The difference in angle of attack was consistent throughout the entire flight (well up until the crash where the values began to converge). The threshold for the optional 'angle-of-attack disagree' warning is, I think, ten degrees. It seems very unlikely that the plane had a twenty degree bank angle for two entire flights.
