What is the primary function of wing flaps?

• A. Increase lift and drag to permit slower airspeed and steeper descent during landing approach.
• B. Increase only lift to maximize climb.
• C. Reduce drag to improve cruise speed.
• D. Provide structural support to wing tips.

Answer: (A)

Wing flaps are high-lift devices that increase the wing’s camber and effective surface when extended. This change lets the wing generate more lift at lower airspeeds, which is essential for a slower approach and a steeper descent during landing without stalling. The flip side is increased drag, which helps control the glide path and descent rate as you approach the runway. So, their main purpose is to enable slower speeds for a safe, controllable landing approach and descent, even though this comes with extra drag. They’re not used to maximize climb, they don’t reduce drag in cruise, and they aren’t structural supports for wing tips.
