The primary function of flaps on an aircraft is to increase lift during takeoff and landing. Flaps are movable surfaces on the wings that extend and change the wing's contour, effectively modifying its aerodynamic characteristics. When flaps are deployed, they increase the surface area of the wing and create a higher camber, which allows the wing to produce more lift at lower speeds. This is particularly beneficial during critical phases of flight such as takeoff and landing, where the aircraft needs to generate sufficient lift at slower speeds.

Increased lift helps the aircraft to depart the runway more efficiently upon takeoff and allows for a steeper descent and slower approach speeds during landing, improving control and safety. Additionally, deploying flaps can also improve the stall characteristics of the wing, making the aircraft more stable while flying at low speeds.

While flaps can influence other aspects of flight dynamics, their main purpose is to enhance lift, facilitating safer operations during takeoff and landing.
