Which is NOT a type of icing found in aviation?

In aviation, understanding the types of icing is crucial for safety and operational efficiency. Icing can occur in-flight and can significantly affect aircraft performance, control, and safety.

Hoar frost, clear ice, and rime ice are well-documented types of icing encountered in aviation.

Hoar frost forms when water vapor in the air changes directly into ice without becoming liquid, essentially leading to a light accumulation of frost, typically in cold and humid conditions.

Clear ice, known for its glossy and transparent appearance, forms when supercooled water droplets freeze upon contact with aircraft surfaces, resulting in a dense and heavy layer of ice. This type of ice can be particularly hazardous because it can build up quickly and impact the aircraft's performance significantly.

Rime ice, on the other hand, is a milky or opaque ice that forms rapidly when supercooled water droplets hit a surface and freeze immediately. It typically occurs in colder conditions and tends to be more brittle and easier to remove than clear ice.

The term "frosted ice" does not correspond to a recognized type of icing in aviation terminology. Therefore, it stands out as the option that does not belong in the context of aviation icing types. Understanding these distinctions is vital for
