In the minimum fuel components, what does the letter B stand for?

• A. Fuel burn
• B. Ballast
• C. Braking fuel
• D. Base fuel

Answer: (A)

In minimum fuel planning, the B component represents Ballast, the extra weight added to achieve proper load distribution and keep the aircraft’s center of gravity within allowable limits. Ballast is used to offset variations in passenger or cargo placement, or to meet weight and balance requirements that the actual fuel and payload wouldn’t guarantee on their own. It isn’t about fuel burn (the fuel that will be consumed), nor about a term like braking fuel or base fuel, which refer to different aspects of fuel planning. So, the B in this context stands for Ballast.
