What happens when you select the FLX RESET?

Selecting the FLX RESET is specifically designed to delete the flex temperature setting. In aviation, particularly in relation to thrust management during takeoff, the flex temperature represents a derived thrust setting that allows for a lower thrust level than maximum power. When the FLX RESET is activated, it clears this setting from the system. This is useful in situations where adjustments need to be made to the thrust to ensure optimal performance and safety by reverting to the default parameters, allowing the flight crew to set the appropriate thrust conditions afresh based on current needs.

Understanding this function is critical, as maintaining the correct thrust setting is essential for the safe operation of the aircraft and can impact factors like performance in takeoff, fuel efficiency, and overall flight safety.
