The particular take-off distance required may be shorter than the available runway length. In this case a lower thrust may be used. Lower thrust settings increase engine life and reduce maintenance costs. The take-off thrust available from a civil engine is a constant value up to a particular ambient temperature.

The maximum takeoff weight (also known as the maximum brake-release weight) is the maximum weight authorised at brake release for takeoff, or at the start of the takeoff roll. The maximum takeoff weight is always less than the maximum taxi/ramp weight to allow for fuel burned during taxi by the engines and the APU.
The team then put those temperatures and headwinds into an aircraft takeoff performance calculator for a variety of different aircraft types, including the Airbus A320 – one of the most popular ...
A330-200 planform view, showing its 10.06 wing aspect ratio and 30° wing sweep Eight-abreast, 2–4–2 economy class The fly-by-wire A330/A340 retains the A320's six-screen glass cockpit. The A330 is a medium-size, wide-body aircraft, with two engines suspended on pylons under the wings.
The maximum takeoff weight (MTOW) or maximum gross takeoff weight (MGTOW) or maximum takeoff mass (MTOM) of an aircraft, also known as the maximum structural takeoff weight or maximum structural takeoff mass, [1] is the maximum weight at which the pilot is allowed to attempt to take off, due to structural or other limits.
The payload fraction of modern twin-aisle aircraft is 18.4% to 20.8% of their maximum take-off weight, while single-aisle airliners are between 24.9% and 27.7%. An aircraft weight can be reduced with light-weight materials such as titanium , carbon fiber and other composite plastics if the expense can be recouped over the aircraft's lifetime.
At take-off, the fan displaces up to 1.3 t (2,900 lb) of air per second, the jet nozzle velocity is almost 1,000 mph (450 m/s) and each high pressure turbine blade generates around 800 hp (600 kW), rotating at 12,500 rpm with their tips reaching 1,200 mph (540 m/s). [6] Rolls-Royce reports the engine is 10 dB quieter than the Trent 700. [11]
