TAC, even you say that the AIP and Jepps do not speak of your little procedure. The ATCO's here don't know of it. Are you making it up as you go along..?
99.99% of pilots here, when asked for a latest divert time, won't factor in where they are in relation to the minima; it is an illogical thing to do. ATC obviously won't either. All anyone is interested in is if they have enough fuel to reach their alternate.
So if the AIP's don't speak of it, the Jepps, the ATCO's and the vast majority of the pilots here do not subscribe to your theories, who is wrong?
I suspect you owe the crew of the A330 an apology.
As for your smug question in the other thread, what part of latest divert time do you really understand?
