Unusable fuel, in some data sets, may be included in BEW or listed separately for balance calculations.

• A. True
• B. False
• C. Sometimes included in BEW
• D. Always listed separately

Answer: (C)

Unusable fuel is the part of the fuel that cannot be burned and remains in the tanks. When compiling weight and balance data, different datasets treat this weight differently. Some datasets include unusable fuel as part of the Basic Empty Weight, so the BEW already accounts for it. Other datasets list unusable fuel as a separate line item to be added in the balance calculations. Because of this variation, the statement is true: unusable fuel may be included in BEW or listed separately, depending on the data source. If it’s in BEW, the fixed weight is larger by that amount; if it’s separate, you’ll include its weight separately in the total calculations.
