Many thanks for all your replies. Zeusman, your bit about extended range tanks reminds me of when we fitted them to a Mk 7 lynx in Detmold as a trial. There it was sat in the hangar with both extra tanks fitted and as much fuel as could be poured in. It was only then that someone had a thought, did some sums and found it was over MAUM!! Ah Detmold... those were the days
