Doze. Check your RED VERTICAL LINE. You will notice it is at 2:10:10.

The initial PULL UP by the PF (F/O) is at 2:10:07. The START of the RED STICK TRACE. In the seconds before a/p disconnect, the Nose dropped 4 degrees, and the a/c was climbing at 1000fpm. It is this AoA increase that dropped her speeds (all three) beyond the 30 knot/second threshold, and caused the speeds loss: but after the disconnection. BEA re: ICE is "LIKELY" wrong.

Of Importance is what the a/c has done prior to 2:10:05. BEA wrote at first that the cg was at 37. They changed that later, in a follow on, to 28. If I had bet my life on their written data, I'd be dead.
