Keg thank you for those figures.I,ll work on a ramp fuel of 100t so assume a burn of roughly 93t.I,ve always been interested in ultra long haul flying and it’s planning.Spent most of my career on the 75/767 but decided to avoid the 78 in the last few years before retirement not liking the way it was introduced and the lifestyle it created.The type seems finally to have settled down in terms of reliability but is very heavy in terms of empty weight although it’s wing is amazingly efficient in the cruise very miserly fuel burns over long distances!Regards Stampe,
