What is the purpose of flap configuration during takeoff and landing?

• A. Flaps increase lift at lower speeds and provide energy management; chosen to meet performance requirements and target approach speeds.
• B. Flaps are used only for cosmetic reasons.
• C. Flaps decrease lift to improve control.
• D. Flaps are used to alter engine power settings.

Answer: (A)

Flap configuration during takeoff and landing is about using lift and drag to control speed and energy. Extending flaps increases the wing’s camber and surface area, which boosts the lift at lower speeds. That means you can become airborne earlier or fly a safer, slower approach without stalling, helping meet required takeoff performance and target approach speeds. At the same time, flaps add drag, which helps slow the airplane and manage descent energy, making the landing approach more controllable and stable. This combination—more lift at lower speeds with added drag—drives the flap setting chosen to meet performance targets and the desired approach speed. Flaps aren’t cosmetic, they don’t reduce lift, and they don’t change engine power settings.
