According to feedback this question or versions of this question have appeared in every exam in the last few months. The question covers the calculation of possible additional fuel including the fuel penalty burnt en route by carrying the additional mass, but in this case the additional fuel is simply limited by the MTOM.

Several candidates have asked whether they should also add the taxi fuel to the total additional fuel possible because it would be burnt during taxi. This is not required in this question because despite being given the block and taxi fuels, the starting premise for the calculation is the Planned TOM 209500 versus the MTOM 220 300 so the taxi fuel has already been accounted for and we are merely calculating the extra fuel that can be carried at T/O that does not cause us to exceed MTOM or MLM.

Differently worded questions may require you to calculate maximum block fuel.

Given the following data:

MZFM 169 000 kg

MTOM 220 300 kg

MLM 179 000 kg

Maximum tank capacity 77 600 kg

Each 1000kg extra in mass incurs a fuel penalty of 350 kg

Block fuel 51 000kg

Planned Trip fuel 41 000 kg

Traffic load 39 000 kg

Taxy fuel 450 kg

Planned TOM 209 500kg

Calculate the maximum possible additional fuel:

Quadrant question: type in the answer.

There are 3 limitations to consider: MTOM, MLM, Tank capacity:
