Which statement about aircraft gross weight is true?

• A. Total weight of the aircraft including fuel and payload.
• B. Weight of the aircraft excluding fuel.
• C. Only the empty weight.
• D. Gross weight has no influence on performance.

Answer: (A)

Gross weight is the total weight of the aircraft at a given moment, including everything on board—empty aircraft structure, engines, payload, and fuel. This total is what directly governs performance: as weight increases, takeoff distance grows, climb rate decreases, and fuel burn changes, all of which affect safety margins and operating limits. The best statement is that the gross weight includes fuel and payload, making it the aircraft’s overall weight. Why the other descriptions aren’t correct: excluding fuel would give a weight figure that isn’t the full loaded aircraft, so it wouldn’t be the gross weight. The empty weight is only the aircraft itself without payload or fuel, not the total. And since gross weight materially affects performance, saying it has no influence would be incorrect.
