What is MTOW?

• A. The maximum landing weight.
• B. The minimum takeoff weight.
• C. The maximum takeoff weight allowed for takeoff.
• D. The mechanical takeoff weight.

Answer: (C)

MTOW is the maximum takeoff weight allowed for takeoff. It’s a certification limit set by the aircraft’s design and regulatory authorities, reflecting what the airplane can safely lift off with given its structure, propulsion, and required climb performance. The weight encompasses everything on board—aircraft empty weight, payload, and fuel—up to that limit. Staying at or below MTOW ensures the aircraft can achieve necessary takeoff performance, satisfy regulatory requirements, and maintain safe margins. This term is distinct from the maximum landing weight, which is the highest weight permitted for landing, and from other nonstandard phrases that don’t represent a real operational limit. So the best understanding is that MTOW is the maximum weight for takeoff.
