Fuel Effeciency
Hi,
First of All, many thanks for your reply....
I would think that the best way to calculate it would be to work out the fuel burned and divide it by the zero fuel weight (Is the payload = to the zero fuel weight of the a/c or the total fuel on burned is included?).
Thus for this instance it would be:
18000(FOD)-10400(FOA) = 7600 LITRES OF FUEL BURNED.
7600/107254(ZFW) = 0.071 Litres of Fuel Burned per kg of weight.
