What is the primary function of flaps during landing?

The primary function of flaps during landing is to increase both lift and drag. Flaps are movable panels on the wings that, when extended, change the wing's shape and increase the surface area. This enhancement in wing configuration allows the aircraft to generate more lift at lower speeds, which is particularly important during the landing phase when the aircraft is approaching the runway at slower velocities.

In addition to increasing lift, flaps also significantly increase drag. This aerodynamic drag helps to slow the aircraft down as it descends and approaches the runway, making it easier to control the descent rate and allowing for a steeper approach angle without the risk of stalling. By facilitating a slower landing speed, flaps provide pilots with greater control during the critical phases of flight, such as the landing approach, ensuring a safer and more stable landing experience.

Thus, the functionality of flaps in enhancing both lift and drag is essential for effective landings, especially in situations where precise control and safety are paramount.
