How many segments are located on the wing leading edge slats?

• A. Five
• B. Three
• C. Four
• D. Six

Answer: (A)

Leading edge slats are made of multiple panels so they can extend in stages and keep a smooth, continuous leading edge as flap settings and angle of attack change. On the A320, the wing leading edge slats are composed of five segments arranged along the span. This five-segment design provides enough surface area and a seamless contour when the slats extend, which helps increase lift and delay stall during takeoff and landing, while still retracting to minimize drag in cruise. The other counts don’t match the actual slat construction for this aircraft.
