What does MTOW represent?

• A. Max takeoff weight -> ramp weight minus taxi fuel
• B. Max landing weight
• C. Minimum takeoff weight
• D. Maximum payload allowed

Answer: (A)

MTOW stands for Maximum Takeoff Weight—the heaviest weight at which an aircraft is certified to begin the takeoff roll. This limit is set during certification to ensure safe performance, structural integrity, and enough climb and acceleration margins under standard conditions.

In practice, ramp weight is the aircraft’s weight with fuel on board at the gate. Before departure you burn taxi fuel, so the actual takeoff weight is ramp weight minus taxi fuel. That takeoff weight must not exceed MTOW.

Other limits exist for different phases or aspects of flight. For example, maximum landing weight is the heaviest permitted weight on landing, which is a different constraint from MTOW. Minimum takeoff weight isn’t a standard limit, and maximum payload is constrained by MTOW and fuel needs rather than being the MTOW definition itself.
