What type of icing is typically expected at lower temperatures when there are increasing ice crystals?

Rime icing is typically expected at lower temperatures where there is an abundance of supercooled water droplets that freeze rapidly upon contact with a surface, forming a rough, opaque coating. This kind of icing occurs mainly in conditions where there's a high concentration of ice crystals, such as in certain types of clouds or when flying through freezing fog, and is common at colder altitudes.

As the air temperature decreases, the supercooled droplets become more prevalent, leading to the formation of rime ice on the aircraft surfaces. This ice often forms more swiftly than other types because it freezes almost instantly upon impact, creating an uneven and frosty appearance.

Recognizing the characteristics of rime icing is crucial for pilots as it can significantly affect aircraft performance, handling, and safety. Understanding how and when rime icing typically forms enhances a pilot's ability to manage flight conditions effectively and take appropriate precautions.
