How do flaps influence landing speed and distance?

• A. Increases stall speed and increases landing distance
• B. No effect on landing distance
• C. Decreases lift and increases approach speed
• D. Flaps increase lift at lower speeds, allowing slower approach and shorter landing distance

Answer: (D)

Flaps increase the wing’s lift at lower speeds, so you can fly a slower approach while still maintaining enough lift to stay airborne. This lets you descend and approach at a lower indicated airspeed, which reduces the energy that must be dissipated on touchdown and typically shortens the landing distance. The flap extension also adds drag, helping you control descent rate and maintain a stabilized approach, which further aids a shorter, safer landing.
