### More about Maximum Takeoff Weight

MTOW defines an upper limit, but the allowable mass for a particular departure can be lower because of runway, weather, obstacles or other constraints.

Payload and fuel contribute to actual takeoff mass. A published maximum does not promise full passengers, full cargo and full fuel on every flight.
