As before, I would like to draw attention to the exchange between Captain DuBois, and Bonin, as regards: "Try Climb"...."But I have held aft stick for some time now."
The general conclusion is that Captain cannot see the Stick, and assumes Bonin has Nose Down, input....
It does not matter what Captain sees, because he suggests CLIMB. But he can see the AI, very nose UP. Why would he suggest CLIMB with a NOSE UP on the dial?
Because he assumes Bonin is pushing NOSEDOWN. If he thought the controls were OK, he would command BONIN to push NOSE DOWN, to lower the NOSE. Are we to believe he has not commanded NOSE DOWN until twenty seconds before impact? And not satisfied himself it is not working?
So, he commands NOSE UP? Neither PILOT is happy with the controls' effects, Captain, because he commands NOSE UP with AI full of blue, (supposedly) and Bonin, because he HAS ALREADY TRIED NOSE DOWN, and it has no effect.
He already attempted NOSE UP, as a solution to non working elevators, "But I have tried (am trying) that".
These are two desperate pilots attempting to figure out INOP or problematic controls.
Think about what they have said, as the CVR explains..... Neither pilot can figure out the Pitch, BUT THEY BOTH KNOW IT IS EXCESSIVELY HIGH.
BONIN has tried both NU AND ND, Captain wants to "TRY NU" ("Try Climbing").
At 10000 fpm descent with the gauge all blue? Don't you believe it. He is satisfied the controls are NOT WORKING.
WHY? TO GET THE NOSE DOWN WITH AN INEFFECTIVE CONTROL and unresponsive A/C....
He is thinking, STUCK elevators, or reversed input.
It is IMPOSSIBLE that these two are on different pages, they both know there is a problem, both have tried conformed, and reverse control positions....
Robert gives up too quickly on the altitude (climb) problem. Or does he? He does not take control, is he satisfied that the controls are INOP? Bonin: "We have no control of the airplane..." He obviously is satisfied the controls are ineffective. ARE THEY? Is Bonin referring to loss of control BEFORE THE CLIMB? Would he not brief the Captain on the earliest onset of problem? THE CLIMB?
