What role do flaps play during takeoff and landing?

Flaps play a crucial role during takeoff and landing by increasing lift at slower speeds while also increasing drag. When deployed, flaps modify the wing's shape, allowing the aircraft to create more lift without the need for higher airspeeds. This is especially beneficial during takeoff, as it enables the airplane to become airborne in a shorter distance and at a lower speed. Similarly, during landing, the increased lift allows the aircraft to fly safely at reduced speeds, which is essential for a controlled approach and touchdown.

The increase in drag associated with flap deployment can also be advantageous, as it helps the pilot to control descent rates and maintain the desired glide path to the runway. This balance of increased lift and drag is a fundamental aspect of operating an aircraft safely near its stall speed during critical phases of flight.

This understanding of flaps emphasizes their importance in enhancing performance and ensuring safe operations during the phases of flight when slow speeds are prevalent.
