In which condition can induction icing occur during flight operations?

Induction icing is a phenomenon that occurs when moisture in the air enters the engine and freezes, particularly affecting the engine's performance. This situation typically arises in conditions of high humidity, especially when flying at lower altitudes where the engine's air intake can ingest supercooled water droplets.

When the relative humidity is high, especially close to the ground, those supercooled droplets can freeze upon contact with aircraft surfaces, including the engine components. This can lead to reduced engine performance due to the formation of ice within the systems that rely on a smooth airflow, such as the inlet and compressor stages of the engine.

In contrast, high altitude with dry air does not provide the moisture necessary for icing, and turbulent weather does not inherently promote the conditions for induction icing unless high humidity is present. Additionally, while icing can occur year-round, it is not limited to the winter months alone, as moisture can be present at any time of the year when conditions are right. Therefore, the scenario where induction icing is likely is while flying near the ground with high humidity.
