In-flight anti-ice system designed to protect wing leading edge and cowls is called?

• A. Wing anti-ice only
• B. Cowl anti-ice only
• C. Wing and Cowls
• D. Tail anti-ice only

Answer: (C)

In-flight anti-ice coverage can target multiple surfaces, and when a system is designed to protect both the wing leading edge and the engine nacelle cowls, it’s called wing and cowls anti-ice. The wing leading edge needs heating to prevent ice from forming on the smooth, aerofoil surface, while the cowls require protection to avoid ice buildup on the engine nacelles. Together, these two areas are addressed by the same anti-ice system, ensuring both critical surfaces stay ice-free during flight. Tail anti-ice is a separate concern and not part of this configuration. So the best fit for protecting both surfaces is the wing and cowls anti-ice system.
