A fixed slot is located near which part of the wing?

• A. At the trailing edge of the wing.
• B. On the fuselage.
• C. Near the leading edge of a wing.
• D. On the vertical stabilizer.

Answer: (C)

Fixed slots are placed at the leading edge because their purpose is to channel higher-pressure air from beneath the wing to the upper surface, energizing the boundary layer and delaying flow separation at high angles of attack. This helps maintain lift at slow speeds during takeoff and landing. A slot at the front of the wing is needed to access undisturbed air and feed the upper surface, which wouldn’t be effective if it were at the trailing edge, on the fuselage, or on the vertical stabilizer. While movable slats can serve a similar lift-increasing role, fixed slots must be near the leading edge to function properly.
