What is compressor icing?

Compressor icing refers specifically to the formation of ice within the compressor section of a jet engine, particularly at the inlet. This type of icing can obstruct airflow through the engine and disrupt its optimal performance. When moisture in the air freezes upon contact with the cooling surfaces of the compressor, it can lead to significant operational issues, including increased engine stall risk and potential engine failure.

The consequences of compressor icing are particularly critical because they directly impact engine efficiency and safety. If ice builds up to a certain extent, it can affect the engine's ability to function properly, leading to reduced thrust and possible engine shutdowns. This issue is most prevalent in certain environmental conditions, such as flying in clouds or precipitation at low temperatures.

Other options describe different types of icing that may occur in aviation but do not align with the specific issue of compressor icing affecting engine operation. For example, ice on aircraft wings influences lift and handling but does not directly affect the engine's functionality in the same manner as compressor icing does.
