Describe the purpose of Engine Anti-Ice systems.

The purpose of Engine Anti-Ice systems is to prevent ice buildup on critical engine components. In flight, particularly at lower temperatures and higher humidity levels, ice can form on various parts of the engine, such as the air intake and compressor. This ice formation can disrupt airflow and lead to a reduction in engine performance or even engine failure.

By utilizing an anti-ice system, operators can ensure that these components remain free from ice accumulation, maintaining the engine’s efficiency and safety. This system is particularly vital for ensuring reliable operations in potentially icing conditions, which can affect not only engine performance but also overall aircraft safety.

The functions of enhancing performance, improving fuel efficiency, or assisting with engine startup may be influenced by well-maintained engines but are not the primary purpose of Engine Anti-Ice systems. Thus, option B correctly identifies the essential function of these systems.
