Because the non-stop flight shall be tankering fuel for up to 20 hours and it costs circa 3% fuel burn per hour to tanker that fuel so to carry just 1,000kg of fuel for the final hour of a 20 hour flight the aircraft is going to take-off with some 1,700kg of fuel of which it shall burn some 700kg just carrying that 1,000kg for 19 hours and that is just 1,000kg, work out the total fuel burn then tankering costs from one to nineteen hours, the fuel burn shall be mega.
