How many slat segments are located on the leading edge of the wing?

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

Answer: (B)

The main idea is that the wing’s leading edge is made up of multiple slat panels, not a single piece, and these segments deploy to increase lift and control stall at high angles of attack. On the A320, there are five slat segments along the leading edge of each wing, allowing a staged deployment and tailored lift distribution as flight conditions change. When takeoff or landing conditions require more lift, these segments extend to produce a higher camber and lower stall speed, while at cruise they stay retracted to minimize drag. Because there are five independent segments per wing, five is the correct count.
