A thread about the conversation between/among the piots? All PF says at a/p loss is "I have the controls"?
Does this suggest the pilot also knew the Flight Law had degraded? No. My point is that the all important question is what he knew, and when. He makes no mention of the Plane's conversion to Alternate? No mention of the loss of AirData? Does he illuminate the type of Alternate? No. Does he believe he is still in Normal Law, and speeds are not unreliable? This all is first verbalized many seconds later. Red Herring?
Neither does he call for the book, and establish other than a mundane reversion to manual control.
This raises no questions amongst the illuminates here?
The salient point is not what has been discovered, it is of no meaning to the crew/pax. What is important is if he was flying without a basic set of start points, how could such a thing happen?
There is also, of course, the possibility that the ironclad conclusions of some are in an area that not even the BEA has ventured, nor will they.
