Which part of the engine is heated by Engine Anti-ice?

Which part of the engine is heated by Engine Anti-ice?

• A. Engine Nacelle
• B. N1 fan casing
• C. Compressor inlet
• D. Tailcone

Answer: (A)

Engine anti-ice is designed to prevent ice buildup on surfaces facing the airstream at the engine inlet by routing hot bleed air to the nacelle. This warms the nacelle’s leading edge and the inner inlet surfaces, keeping airflow smooth into the compressor and preventing ice from forming or shedding into the intake. The heating is targeted at the nacelle assembly itself, not at the N1 fan casing or the compressor inlet region, and it does not heat the tailcone. So, the part heated by Engine Anti-ice is the engine nacelle.
