One main function of flaps during approach and landing is to

• A. Provide the same lift at slower airspeed
• B. Decrease lift with no change to speed
• C. Increase lift to allow slower approach speeds
• D. Increase drag only

Answer: (C)

Flaps are used on approach and landing to increase the wing’s lift at lower speeds. By increasing camber (and sometimes effective wing area), the lift coefficient rises so the airplane can fly slower while still producing enough lift to stay airborne. This lowers the stall speed and allows a safer, more controllable descent during the approach. At the same time, flaps also add drag, which helps you manage airspeed and descent angle, but the key purpose is enabling slower approach speeds by increasing lift.
