What type of ice would you classify based on a rough and milky appearance?

The type of ice characterized by a rough and milky appearance is classified as rime ice. Rime ice forms when supercooled water droplets in clouds come into contact with a surface, such as an aircraft or a tree, and freeze upon impact. This process creates a texture that appears rough and can often seem opaque or milky due to the presence of trapped air bubbles within the ice structure.

Rime ice typically develops in conditions where temperatures are low, and the supercooled droplets are abundant. It tends to accumulate on the leading edges of wings and other exposed surfaces on an aircraft, which can greatly affect performance and safety.

Recognizing rime ice is essential for pilots and air traffic controllers, as it can impact aircraft handling characteristics. Understanding the different types of ice, including their formations and appearances, helps in assessing potential hazards during flight operations.
