Today´s topic will be all about Flex Temperature, what is good for and how often do we use it.
Prior to every takeoff you need to perform takeoff calculations, giving you the speed V1, VR, and V2 and they necessary flex temperature to get the needed thrust setting for the takeoff roll and lift off and eventually first climb out.
The flex temperature is a assumed outside air temperature, relatively high, forcing the FADEC ( Full Authority Digital Engine Control)unit to reduce the thrust output to reduce the engine wear of the turbine in such expected "hot" temperatures. So once applying takeoff thrust by setting the thrust levers to the FLX/MCT detent, the airplane will roll down the runway with a lower power setting thus increasing the takeoff with higher speeds and decreasing the stop margin available. But you can always gain full available power by putting the levers into the TOGA detent position.
The result of using a high flex temperature is that is the speeds are higher for liftoff, cause the plane won´t accelerate as quickly as it could and therefore using up more runway, resulting in a shorter stop distance and case of a rejected takeoff, obviously!
If we would have used a lower flex temperature, the liftoff speed is much lower and the stop distance is much greater compared to the higher flex temperature.

So the conclusion of that is, the lower the flex temperature, so the fake outside air temperature for the FADEC, the more power will be set when applying thrust, so the closer it is to TOGA. The higher the flex temperature the more the engine is derated resulting in longer takeoff roll with higher speeds and at the same time reducing the engine wear.
