How do wing flaps impact an aircraft during takeoff?

• A. They decrease lift
• B. They increase lift and reduce stall speed
• C. They create drag only
• D. They stabilize the aircraft

Answer: (B)

Wing flaps play a crucial role during takeoff by increasing lift and reducing stall speed. When the flaps are extended, they change the wing's camber and increase its surface area, which allows the wing to generate more lift at a given speed. This characteristic is particularly beneficial during takeoff when the aircraft is generating enough lift to become airborne. Additionally, extending the flaps helps to lower the aircraft's stall speed. Stall speed is the minimum speed at which the aircraft can maintain level flight without losing lift. By increasing effective lift, flaps allow the aircraft to safely take off at lower speeds, which is particularly important for operations on shorter runways or in obstacle-rich environments. The other options do not accurately represent the impact of wing flaps during takeoff. For example, while flaps do create drag, this is not their primary purpose during takeoff, and the additional drag is often manageable and even beneficial for controlling the aircraft's ascent.
