Which component of an aircraft is responsible for increasing lift efficiency?

The component responsible for increasing lift efficiency on an aircraft is flaps and slats. These devices are pivotal during takeoff and landing phases, as they modify the airflow over the wing. When deployed, flaps increase the surface area of the wing and change its curvature, allowing the wing to generate more lift at lower speeds. Slats, which are located at the leading edge of the wing, also help enhance lift by delaying airflow separation, thus improving the wing’s performance during critical phases of flight. Together, flaps and slats enable the aircraft to fly safely and efficiently at slower speeds, making them essential for optimizing lift during all phases of flight.
