*Given:maximum allowable take-off mass 64 400 kg*

maximum landing mass 56 200 kg

maximum zero fuel mass 53 000 kg

dry operating mass 35 500 kg

estimated load 14 500 kg

estimated trip fuel 4 900kg

minimum take-off fuel 7 400 kg

Find the maximum allowable take-off fuel:

maximum landing mass 56 200 kg

maximum zero fuel mass 53 000 kg

dry operating mass 35 500 kg

estimated load 14 500 kg

estimated trip fuel 4 900kg

minimum take-off fuel 7 400 kg

Find the maximum allowable take-off fuel:

**ANSWER:11.100KG**

Why answer 11.100KG

I take dry operating mass(mass of plane with no usable fuel and traffic load) and estimated load. This is total weight of plane without fuel.And If we substract it from maximum allowable take off mass than I found 11.400KG

35.500+14.500=50.000KG and

64.400-50.000=11.400KG ?????????
