This is really confusing me.
If an Aircraft has an empty weight of 12 tonnes and a zero fuel weight of 17 tonnes, what is the max payload it can carry?
I would say 5 tonnes, zero fuel weight - empty weight. Is this right?
Then it says the maximum take off weight is 21 tonnes. So does this mean that the maximum fuel weight is 21-17 = 4 tonnes?
Because the question says calculate the lift generate by the aircraft in kN after the aircraft has used 22,000lbs of fuel.
But 22,000lbs = 10 (metric) tonnes? How can it use this if the max fuel weight is 4 tonnes?
Its probably just me misinterpreting something but any help would be greatly appreciated
Thanks in advance
