What type of icing is characterized by clear, glossy ice?

Rime Ice
Clear Ice
Mixed Ice
Induction Ice

The correct answer is: Clear Ice

Clear ice is an icing type that forms under specific atmospheric conditions typically associated with supercooled liquid water droplets. When these droplets hit an aircraft's surface, they spread out and freeze slowly, creating a smooth, glassy surface. This type of ice is particularly hazardous because it can add significant weight to the aircraft, disrupt airflow over the wings and control surfaces, and reduce performance. In contrast, rime ice is characterized by a more opaque appearance, resulting from smaller droplets freezing rapidly upon impact, leading to a rough surface. Mixed ice contains both clear and rime ice characteristics, presenting a combination of smooth and rough areas. Induction ice refers to ice that forms in the engine induction system, which does not apply in this question regarding external surface icing. Thus, the distinctive features of clear ice, including its visual properties and formation conditions, affirm its identification as the correct answer.
