Going B
Thanks for that but with a reasonable paylod on QF long haul it would have to fly slower to get the range (up to 1 hour longer on a certain route). That figure is what Airbus is quoting no different to Cessna/Piper advertising "It has this range and can carry this much" but do the sums and it cant do both at the same time.
From current planning figures the whale will have to fly slower to make the distance with a reasonable payload = longer time on ur but.
Defeats the purpose of having a bigger toy when the sandpit takes longer to traverse.
