Hi Halo,. .. .Our Nigel on best bitter made his point well. I'd just like to say that there would be no point in diverting when you will end up in exactly the same fuel scenario as you would when 'committing' and landing at LHR. I have experienced this on two occasions many years ago as an ENG on the Classic. Big question mark over my head whilst making an approach into EMA on minimum fuel.. .. .Your point, <<There is no point us finding this out at anywhere less than 6 DME because the departure controller will then be committed with his current line-up>>.. .. .My sincere hope was that the departure controller will abandon his line up if I declare a MAYDAY because I now KNOW I will land with less than 'reserve fuel'. (30 mins. at 1500 ft.) An unlikely scenario at 6 DME I grant you, but nevertheless possible.. .. .Our instructions are a 'PAN' if you think it is possible that you may land with less than reserves, and a MAYDAY if 'KNOW' you will land with less than reserve fuel.. .. .It's good to talk about these things. <img border="0" title="" alt="[Smile]" src="smile.gif" /> . .. .We are all counting on you. <img border="0" title="" alt="[Wink]" src="wink.gif" /> . .. .Regards. .Exeng
