Which variant has the higher maximum zero fuel weight?

• A. Variant 700
• B. Variant 900
• C. Both
• D. Not specified

Answer: (B)

Maximum zero fuel weight is the most the aircraft can weigh without any usable fuel on board. It’s set by the airframe’s strength and the allowable center of gravity when there’s no fuel, so it basically caps how much payload you can carry before you add fuel.

Between variants, the one built for higher payload capability or with a stronger, larger structure can carry more weight with zero fuel, so its MZFW is higher. The lighter or more lightly stressed variant can’t carry as much payload without exceeding structural or CG limits, so its MZFW is lower. That’s why the higher-capacity variant has the higher maximum zero fuel weight.
