Flaps are typically used to improve the lift characteristics of the wing. When flaps are deployed, they change the shape and curvature of the wing, increasing the surface area and generating more lift at lower speeds. This is particularly beneficial during critical phases of flight such as takeoff and landing, where additional lift is needed to maintain control and safety. By allowing the aircraft to fly safely at slower speeds, flaps enable better performance during approaches and enhance the aircraft's ability to operate on shorter runways.

In contrast, while some may mistakenly believe that flaps can be used to increase aircraft speed, they actually serve to lower the stall speed and facilitate slower flight, rather than enhance speed. Additionally, flaps can help manage the angle of descent, but their primary function is not to reduce descent rates during takeoff; that is more related to the overall aerodynamic profile and configuration of the aircraft during flight. Lastly, flaps do not contribute to engine performance; they interact with the airflow over the wings rather than influencing the propulsion system.
