Sorry boys your numbers are well out.
Approx 9 tonnes/hr for the 345 on long heavy sector, short ZRH down to about 8t/hr.
So trip 14.25hrs - 125t
Alt OOMS 45 mins - 5 t
Final res - 4 t
Cont - 3 t
Holding - 10 t (due fog in DXB that day.)
Total on board about 145 -150 T at take-off.
EK A345 Capt.
nb Figures are rough guesstimate, but will be quite close.
A345 is a heavy thirsty machine. Aps weight in Ek config is about 185t, MTOW is 372/3t.
B772 LR burns nearer 7.5 t/hr, so much better fuel economy for similar payload.
EK will most likely keep it for a while despite the fuel burn, as there are more to aircraft finances than just how much petrol it uses.
