Which statement accurately describes the relationship between Maximum Allowable Gross Weight, Basic Empty Weight, and Useful Load?

Which statement accurately describes the relationship between Maximum Allowable Gross Weight, Basic Empty Weight, and Useful Load?

• A. Useful Load equals Maximum Allowable Gross Weight minus Basic Empty Weight.
• B. Useful Load equals Basic Empty Weight minus Maximum Allowable Gross Weight.
• C. Useful Load equals Maximum Allowable Gross Weight plus Basic Empty Weight.
• D. Useful Load is unrelated to these weights.

Answer: (A)

Understanding weight balance for an aircraft means seeing how much you can add on top of the fixed empty airplane weight without exceeding the maximum allowed takeoff weight. The Useful Load is exactly the amount available for payload (passengers, baggage) and usable fuel. The maximum allowable gross weight sets the ceiling for the total weight. So the difference between that ceiling and the basic empty weight is the Useful Load. In formula terms, MGW minus BEW equals Useful Load. This also means BEW plus Useful Load equals MGW, and you must keep their sum at or below the maximum to fly safely. If BEW goes up, the room for payload and fuel shrinks accordingly; if you add fuel, you must reduce payload to stay within the limit. The other ideas imply negative or impossible relationships (or claim there’s no connection), which doesn’t reflect how the weights are used in flight planning.
