MTOW stands for Maximum Takeoff Weight. It is the maximum weight at which an aircraft is certified to take off. This weight includes the weight of the aircraft itself and the weight of all fuel, passengers, cargo, and other payload onboard.
MTOW is important because it is a critical design and operational limit for an aircraft. The aircraft must be designed, built and maintained to operate at or below this weight safely. The MTOW is established by the aircraft manufacturer and is verified and certified by regulatory authorities such as the Federal Aviation Administration (FAA) or European Aviation Safety Agency (EASA).
The MTOW is important for several reasons:
Safety:
The aircraft must be able to take off and climb safely at the MTOW. If the aircraft is overloaded, it may not be able to achieve the necessary performance to take off and climb safely.
Performance:
The MTOW affects the aircraft's performance, including its takeoff and landing distances and climb and cruise performance. Operating at or below the MTOW ensures the aircraft performs as intended.
Maintenance:
The aircraft's systems and components are designed to handle the loads imposed by the MTOW. Operating at or below the MTOW ensures that the aircraft's systems and components will not be overstressed, which if not correctly respected can lead to damage or failure.
Flight planning:
The MTOW is a critical factor in flight planning, as it affects the amount of fuel that must be carried, the number of passengers and cargo that can be carried, and the aircraft's performance during takeoff and landing.
In summary, MTOW is the maximum weight that an aircraft is certified to take off. This weight includes the weight of the aircraft itself and the weight of all fuel, passengers, cargo, and other payload onboard. The MTOW is important for safety, performance, maintenance and flight planning and is verified and certified by the regulatory authorities.
