as Tucumse's query as to whether the switch being set to “off” stopped internal processing has not been answered, I am assuming that the switch had not been turned off by the crew
Your logic escapes me again. Just because no one has answered a relevant question, the question should be ignored and a conclusion reached that fits your theory? That sounds like MoD logic.
it makes no sense that they would have switched it off anyway.
Don't worry about the switch
I read long ago that switching off the box was a way of clearing radio emc problems. Even if not true surely the switch position is very important as the system’s data is the basis of MoD’s argument? Not conclusive, but an unexplained coincidence that needs an answer.
– the data within was meaningful right up to impact and
The data is only meaningful if the pilots can read and make use of it. If the display was switched off…
I can’t answer my questions, or yours, but neither does anyone else. You raise good points but I think you reach pretty odd conclusions. Have you put all this before Lord Phillips? Probably best if you ask the questions but avoid the conclusions.
