If all seats are occupied, full baggage weight is carried, and all fuel tanks are full, what will be the weight condition of the aircraft?

• A. It will be heavier than empty weight but within MTOW.
• B. It will be under zero fuel weight.
• C. It will equal the maximum landing weight.
• D. It will be in excess of maximum takeoff weight.

Answer: (D)

MTOW is the upper limit for what the airplane can weigh at takeoff. It is the sum of the empty weight plus payload (passengers and baggage) and usable fuel that the aircraft is certified to lift. If every seat is occupied, all baggage is loaded, and all fuel tanks are full, that total will exceed the certified takeoff weight in most aircraft. So the weight condition is in excess of the maximum takeoff weight. The other descriptions don’t reflect this situation: zero fuel weight would mean no usable fuel, which isn’t the case here; maximum landing weight is a separate limit used for landing, not for takeoff; and being only heavier than empty weight still implies there’s a payload and fuel, which typically pushes it past MTOW.
