Which system prevents ice buildup on critical surfaces of the aircraft?

• A. Electrical System
• B. Ice Protection System
• C. Landing Gear System
• D. Fuel System

Answer: (B)

Ice buildup on critical surfaces can disrupt airflow, reduce lift, and compromise control. To keep those surfaces ice-free, aircraft rely on an Ice Protection System that handles both anti-ice and de-ice functions. Anti-ice prevents ice from forming on surfaces like wing leading edges and engine inlets by heating them, often with bleed air or electric heat. When ice has already formed, de-ice methods remove it, such as inflatable boots or sustained heating. The Electrical System may power some of these heaters, but the system’s primary purpose is to prevent and remove ice on the critical surfaces themselves. The other systems don’t address ice accumulation on these surfaces.
