Which icing type is a combination of clear and rime?

• A. Mixed ice
• B. Clear ice
• C. Rime ice
• D. Ice fog

Answer: (A)

A coating that combines both clear and rime ice is called mixed ice. It forms when icing conditions include a mix of droplet sizes or when temperature and liquid water content vary during the flight, producing patches of transparent ice alongside rough, milky ice. That blend is exactly what makes it a combination of the two types. Clear ice is glossy and forms from large droplets in near-freezing temperatures, while rime ice is rough and white from small droplets at colder temperatures. Ice fog is not a wing icing type; it’s a fog composed of ice crystals in the air, not a surface coating on the aircraft.
