How do flaps affect takeoff distance?

Deploying flaps indeed increases lift at lower speeds, which directly contributes to reducing takeoff distance. When flaps are extended, they alter the wing's shape, increasing the camber and surface area. This change allows the aircraft to generate sufficient lift at lower airspeeds than would be possible with the flaps retracted.

During takeoff, the increased lift provided by the flaps allows the aircraft to become airborne sooner, which translates to a shorter takeoff roll on the runway. This is particularly advantageous on shorter runways or in conditions where maximum performance is needed, such as high-density altitudes or wet runway conditions.

The increased lift at lower speeds is crucial because it enables the aircraft to reach the necessary takeoff speed more efficiently. As a result, the aircraft can achieve a positive rate of climb sooner than it would without the flaps, further enhancing takeoff performance.
