What does the wing anti-ice system do on the 737-800?

• A. Prevents engine failure
• B. Protects the three inboard leading-edge slats
• C. Improves wing shape during take-off
• D. Enhances fuel efficiency

Answer: (B)

The wing anti-ice system on the 737-800 specifically functions to protect the three inboard leading-edge slats from ice accumulation. Ice buildup on these components can severely affect the aircraft's aerodynamics, leading to a loss of lift and control, especially during critical phases of flight like take-off and landing. By ensuring these areas remain clear of ice, the system helps maintain optimal performance and safety of the aircraft in cold, icing conditions. The other options do not accurately represent the primary purpose of the wing anti-ice system. Preventing engine failure, for example, is more relevant to engine ice protection systems rather than wing anti-ice functionality. While wing shape can be influenced by maintaining smooth airflow, the primary role of the anti-ice system is to prevent ice formation on specific wing components. Enhancing fuel efficiency is also not a direct function of the wing anti-ice system; its main purpose is safety and performance during icing conditions.
