I think Blind Pew needs to follow his own advice and step back...
The crew were faced with false stall warnings, overspeed warnings, control law warning, turbulence, probable dutch roll and a stab that was moving to the aft limit for whatever b****y reason.
Ten out of ten for drama, five out of ten for accuracy. False stall and overspeed warnings are to be expected wth unreliable IAS. Control law warning - no big deal, alternate law is benign. Turbulence? An assumption. Dutch roll? And assumption. Moving stab? Not an issue. It was functioning as designed and the crew would not likely even be aware of the stab position.
I very much doubt if anyone in the crew had ever flown manually at altitude.
I have flown an Airbus manually at altitude. It's exactly the same as flying it at 10,000 feet thanks to the flight control laws, either in Normal or Alternate law. It's not an issue.
The body tenses with stress and fear and primeval instinct is to wrap oneself up in the foetal position - which could have resulted in the PF inadvertently putting a nose up input on the stick while he was sorting out the roll and what was really happening.
Errrrr - you don't accidentally put full back stick on, and not for 30 secs. Your arm will get very tired.
They had very little time and whether or not they had any correct speed indications they did not have the time to diagnose what was right or wrong.
Thats why you have an unreliable airspeed recall item.
BA nearly lost a 747 - the LAX one- as the crew didn't understand the basics of the fuel system and that technology goes back to Noah.
They also had the whole night to play around with it and get it wrong.
There was never any chance of losing the aircraft, and the issue which manifested itself only became apparent at top of descent and would have resolved itself of it's own accord anyway. Lots of fuss about nothing.
The myriad of posts trying to fathom out the computer system shows that it is not understood by the average bloke.
Fortunately 'average blokes' aren't let loose on multi-million dollar airliners. They have to have a lot of training first, which is why many Airbus experienced pilots find this kind of speculation tedious.
