In CNAF fuel planning, the fuel amount is expressed in which unit?

• A. Gallons
• B. Pounds
• C. Kilograms
• D. Liters

Answer: (B)

In CNAF fuel planning, fuel amount is expressed in pounds because fuel quantity is treated as mass rather than volume. Mass stays constant even as temperature and density change, so planning and calculations (like fuel burn, weight, and center of gravity) rely on a stable measure. This mass-based approach aligns with how fuel weight affects aircraft performance and balance, making pounds the practical standard for planning. Volume units (gallons or liters) would require continually adjusting for density/temperature, which adds complexity and potential error. Kilograms could be used in SI contexts, but CNAF uses pounds for consistency with established Navy aviation practices.
