What form of icing is created through the combination of clear and rime ice?

The combination of clear ice and rime ice results in mixed ice. Clear ice forms when supercooled liquid water droplets freeze on contact with an aircraft's surface, creating a smooth, transparent layer. Rime ice, on the other hand, develops when small supercooled droplets freeze rapidly upon impact, creating a rough, white appearance. When these two types of ice are present together, they form mixed ice, characterized by a combination of the two forms and presenting challenges for aircraft performance and safety.

Understanding mixed ice is crucial for pilots and meteorologists, as it can occur in various atmospheric conditions and poses significant risks during flight. It’s important to be aware of the characteristics of different types of ice, as well as the conditions under which they can form, to anticipate and mitigate potential hazards during flight operations.
