If flight is to be made into known or forecasted moderate icing what does it need?

• A. Operational de-icing and anti-icing
• B. Extra fuel
• C. Ground observers
• D. Higher power setting

Answer: (A)

When flying into known or forecasted moderate icing, you must have operational ice protection: the ability to both prevent ice from forming and to remove ice that has already accumulated. Anti-icing systems keep ice from building up on critical surfaces, while de-icing systems remove ice so aerodynamics remain effective. In icing conditions, ice on wings and control surfaces can rapidly reduce lift and increase drag, potentially leading to a stall or loss of control, so having functioning ice protection and knowing how to use it is essential for safety. Other options don’t address the core hazard: extra fuel doesn’t prevent ice buildup, ground observers aren’t required for icing, and simply increasing power isn’t a reliable substitute for proper ice protection.
