Flex temp is a technique used to produce cost savings through increased engine life and reduced overhaul and fuel costs [1] for airliners by allowing them to take-off at less than rated thrust. [2] For Airbus and Fokker aircraft the technique is known as flex temp or just flex.
A more tangible benefit is the increased ability to exit the runway at a specified turnoff point. The European Aviation Safety Agency certified the system, initially for use on the Airbus A380, in 2009. [1] The second Airbus product to incorporate BTV will be the Airbus A320 family, which is much more widely used around the world than the A380 ...

The Airbus A320 is a low-wing airliner with twin turbofans and a conventional tail. The Airbus A320 family are narrow-body (single-aisle) aircraft with a retractable tricycle landing gear and powered by two wing pylon-mounted turbofan engines. After the oil price rises of the 1970s, Airbus needed to minimise the trip fuel costs of the A320.

The takeoff decision speed V 1 is the fastest speed at which the pilot must take the first actions to reject the takeoff (e.g. reduce thrust, apply brakes, deploy speed brakes). At speeds below V 1 the aircraft can be brought to a halt before the end of the runway. At V 1 and above, the pilot should continue the takeoff even if an emergency is ...
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 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.
