What is the role of engine anti-ice inlets and accessories during icing conditions?

• A. Engine anti-ice governs anti-ice for engine inlets and accessories; activated per icing conditions per SOP.
• B. Engine anti-ice heats wing leading edges.
• C. Engine anti-ice is not used on A320.
• D. Engine anti-ice only functions during takeoff.

Answer: (A)

Engine anti-ice is the system that protects the engine inlet and accessories from ice buildup. In icing conditions, bleed air is routed to heat the engine inlet and the accessories anti-ice circuit, keeping the surfaces above freezing and preventing ice from narrowing the airflow or fouling the engine. This is controlled by procedures and the airplane’s ice-detection logic, so it is activated as needed based on icing conditions and SOP, not just during takeoff. The wing anti-ice is a separate system, so this option correctly describes the engine-side function, while the other statements describe unrelated systems or incorrect usage.
