What is the definition of mixed ice?

• A. Completely clear ice
• B. A mixture of clear and rime ice
• C. Ice with a glass-like appearance
• D. Ice that does not stick to surfaces

Answer: (B)

Mixed ice refers to a combination of two distinct types of ice, specifically clear ice and rime ice. Clear ice forms when supercooled water droplets freeze upon contact with a surface, creating a smooth, shiny layer of ice. Rime ice, on the other hand, forms when water droplets freeze more quickly on contact, resulting in a rough, white, and opaque appearance. When these two types of ice coexist, it creates what is known as mixed ice. This can have implications for aviation safety, as mixed ice can affect an aircraft's performance and handling characteristics. Pilots and crew members need to recognize and understand mixed ice to manage the risks associated with it effectively. The other options focus on single characteristics of ice types or different scenarios altogether, which do not capture the essence of mixed ice.
