How does aircraft configuration impact landing distance?

Using flaps can reduce landing distance because they increase the lift generated at slower speeds and enhance the aerodynamic efficiency of the aircraft during approach and landing. When the flaps are extended, the airflow over the wings is modified, allowing the aircraft to maintain controlled flight at lower speeds. This capability enables the pilot to approach the runway at a steeper angle and land more gently, which leads to a shorter landing roll once touchdown occurs.

Additionally, the extended flaps increase drag, which helps in slowing down the airplane more efficiently during the landing process. By configuring the aircraft in this manner, pilots can optimize landing performance and reduce the distance required to stop on the runway. Thus, the correct answer highlights the importance of proper configuration in achieving effective landing distances, particularly through the use of flaps.
