Mr Angry:
"The duty length could be a consideration for the mishap".
Now there is a ground-breaking thought. Have you thought about passing on this amazing revelation to the AAIB et al?
"For the sake of an hour - who cares".
Well, I would suspect that the AAIB, the CAA, the BCAA and Uncle Tom Cobbly and All would care if the crew were one hour over the top so lots of people care. This is hardly surprising.
I was simply responding to the statement that the crew "had better not be over 13 hours or there would be trouble". I have tried to point out that under Belgian FTLs, 13 hours is irrelevant.
But then, what's an hour between friends?
