Slotted flaps are aerodynamic devices found on the wings of aircraft, designed to improve lift during takeoff and landing. They consist of a movable panel that extends downward and backward, creating a slot between the flap and the wing. This slot allows high-energy air to flow from the wing's upper surface to the lower surface, enhancing lift and delaying airflow separation. These flaps are particularly useful for larger aircraft, such as those used in commercial aviation, as they enable safer operations at lower speeds. By increasing the wing's effective surface area, slotted flaps help pilots maintain control during critical phases of flight, such as approach and landing.
