Hazelnuts39 Pls. take note of the VS and the Attitude, two seconds prior to a/p loss.
Note that in two seconds the actual VS had changed from 500 fpm up to a like number down. That is remarkable, and the a/c was at what weight?
The Nose was in transit as the VS reversed, and they were not in tune.
I think the a/p was attempting to rate the UPDRAFT with elevators, and it eventually required too much ND (v/v AoA) to keep up (level). The Screen reported ND at handoff. Not Level.
Have you a reference for the deflection of Vanes due airmass? That geometry is beyond my current take. Something was causing the Vanes to read crazy high, and it was not 'cruise Nose'.
