Which statement best describes the anti-ice selection for takeoff given the weather scenario provided?

• A. Wing anti-ice only
• B. No anti-ice required
• C. Cowl heat only
• D. Cowls and Wings

Answer: (D)

In icing conditions, the surfaces most at risk during takeoff are the wing leading edges and the engine inlet. Ice on the wings reduces lift and raises stall speed, while ice in or around the engine inlet can harm engine performance. To keep both surfaces protected through the critical takeoff and initial climb, you apply anti-ice to both the engine cowl and the wings. That’s why selecting both cowls and wings is the best choice. If you only protect one surface, the other remains vulnerable to ice buildup; assuming no anti-ice is needed is unsafe in these conditions.
