Whether or not the a/c was reporting it, we are only sure of the crew's cognizance at 2:10:16. That is eleven seconds to be in the dark as to what is wrong.
Loss of Autopilot does NOT mean fly "PITCH AND POWER". It means fly...
You continue to studiedly ignore what RR and myself, among others, have pointed out, that the a/c was not clearly indicating that UAS was the problem, and that the computers did not necessarily include the crew from the outset of suspected duff speeds.
The reference is to what the a/c displayed, RESULTS of bad data.
Question. If the a/c had ceased displaying IAS from the outset of suspected bad speeds, would not the pilots have had obvious cue of loss of Airspeed (literally)
Displaying any cue that is known to be false is counter to good design, if said cue can be left out.with impunity.
Why waste precious time in a situation that is easily remedied with Pitch and Power?
The fact that pilot started handling the a/c demonstrates his belief it needed handling, period, speeds or not.
