Dozy, you might want to step back and take a deep breath. And then try reading what others wrote. You continue to argue on tangents; tangents that seem relevant but upon close inspection are nothing more than misdirections.
By misinformation and flannel, doth the truth become obscured :-). I must admit to a little disappointment at the level of discussion re AF447 and the same in the tech log thread, where one would expect at least some technical discussion about the report's recommendations. A few months ago, there were serious discussions about all kinds of issues, but now that the final report has been issued, no one seems to want to talk about it in any serious way at all.
Perhaps there are those who would prefer both threads to become trivialised, so that no external readers of influence take it too seriously, or is that too cynical ?...
