Which statement correctly describes rime icing?

• A. Rime ice is a heavy, clear deposit
• B. Rime ice forms by the freezing of large water droplets
• C. Rime ice has a rough surface and is milky and opaque
• D. Rime ice forms only during the night

Answer: (C)

Rime icing is characterized by its formation process and physical properties. Rime ice develops when supercooled water droplets freeze quickly upon contact with a surface, such as an aircraft wing, creating a rough and irregular texture. The rapid freezing of these droplets traps air within the ice, resulting in a milky and opaque appearance, distinguishing it from other types of icing. Understanding the characteristics of rime icing is essential for pilots and those involved in aviation safety, as it can significantly impact aircraft performance and safety. Recognizing these features helps in identifying rime icing conditions, which can occur in various atmospheric situations, not limited to nighttime.
