What is the purpose of using flaps during landing?

• A. To improve fuel efficiency
• B. To decrease landing speed and increase lift
• C. To shorten the landing roll only
• D. To level the aircraft in flight

Answer: (B)

Using flaps during landing primarily serves to decrease landing speed and increase lift. When deployed, flaps alter the shape of the wing, which enhances its aerodynamic properties. This modification allows the wing to generate lift at lower speeds, enabling the aircraft to maintain controlled flight during the final approach and landing phases. By lowering the speed at which the aircraft can land, flaps allow pilots to approach the runway more slowly and with a steeper angle of descent. This capability is particularly useful in situations where a shorter runway or obstacles near the flight path require a more precise and shorter landing distance. Additionally, the increased lift provided by the flaps assists in maintaining control of the aircraft as it approaches the ground, reducing the risk of stall. While flaps may influence landing roll distances and other aspects of flight, their primary role in landing is to enable a slower, controlled landing by enhancing lift, thus making option B the correct choice in this context.
