What is meant by minimum fuel as used in weight and balance computations?

• A. No more fuel than the quantity necessary for one-half hour of operation at rated maximum continuous power. It is the maximum amount of fuel used in weight and balance computations when low fuel may adversely affect the most critical balance conditions.
• B. The minimum fuel is the fuel required for taxiing.
• C. The fuel remaining after landing.
• D. The maximum allowable fuel in the tanks.

Answer: (A)

Minimum fuel in weight and balance calculations is a conservative fuel quantity used to model the aircraft’s most critical loading condition. It represents the amount of fuel that would be on board for planning purposes in a worst‑case balance scenario, rather than the actual planned trip fuel. The standard definition used here is the quantity needed for about one-half hour of operation at rated maximum continuous power, which provides a consistent baseline to ensure that, even as fuel is burned and the distribution changes, the airplane’s weight and center of gravity stay within permissible limits. This isn’t taxi fuel, remaining fuel after landing, or the tank’s maximum capacity; it’s the defined minimum used to evaluate the most unfavorable balance condition.
