What is the resulting configuration if airspeed is above 210 kts for flaps 2 to 1?

When the aircraft is configured from flaps 2 to flaps 1 while the airspeed is above 210 knots, the system automatically transitions to a lower flap setting designed to optimize performance and safety.

In this case, flaps 1 is established as a step that allows the aircraft to maintain a balance between lift and drag while ensuring stability at higher speeds. It is particularly beneficial for maintaining aerodynamic efficiency during cruise or descent phases of flight. Flaps 2 provides a greater lift at lower speeds but is not necessary or efficient at speeds exceeding 210 knots.

Therefore, transitioning to flaps 1 at these higher airspeeds is a standard operating procedure to prepare the aircraft for further actions, such as slowing down for approach or descent without risking excess drag or stall conditions that could arise if using a higher flap setting.

This understanding is crucial, especially during approach and landing phases, where flap configuration directly impacts the aircraft’s performance and safety.
