What is the function of flaps on an aircraft?

• A. To increase drag for better speed control
• B. To increase lift during takeoff and landing and to enhance the aircraft's stability and control
• C. To lower the aircraft's center of gravity
• D. To stabilize the aircraft during turbulent weather

Answer: (B)

Flaps are movable panels on the wings of an aircraft that play a critical role in enhancing the aircraft's performance during specific phases of flight, particularly during takeoff and landing. Their primary function is to increase lift at lower speeds, which is essential for safely leaving the ground and returning to it. When extended, flaps increase the curvature of the wing, which generates more lift at a given airspeed. This allows the aircraft to take off and land at slower speeds, reducing the required runway length. In addition to this lift enhancement, deployed flaps also increase drag, which helps in controlling the descent rate during landing and allows for more precise approaches. Furthermore, by providing additional lift and drag, flaps contribute to the overall stability and control of the aircraft in these critical phases of flight. Thus, flaps are integral to ensuring safety and efficiency in aviation operations, making their function vital for pilots to understand and effectively manage.
