What is the term for a combination of rime and clear ice that includes both of their dangerous effects?

• A. Clear ice
• B. Mixed ice
• C. Supercooled water
• D. Structural ice

Answer: (B)

The term "mixed ice" refers to a combination of rime ice and clear ice, highlighting the dangers associated with both types. Rime ice forms when supercooled water droplets freeze upon impact with an object, resulting in a rough, opaque coating. This type of ice can accumulate quickly and affects aircraft in a way that can disrupt airflow over wings and control surfaces. Clear ice, in contrast, forms from larger supercooled droplets that freeze more slowly, creating a transparent layer that can add significant weight and alter the aerodynamic properties of the aircraft. By acknowledging both rime and clear ice within the term "mixed ice," it captures the symptoms and risks associated with these ice forms, leading to serious implications for aircraft performance and safety. Pilots and operators must be particularly wary of mixed ice conditions, as they can lead to an increased risk of ice accumulation and potentially dangerous flight characteristics. Understanding this term is crucial for effective decision-making regarding flight safety and operational procedures in icy conditions.
