A) in the cloud at warmer than freezing temperatures

C) in the cloud at well below freezing temperatures
D) outside the cloud at below freezing temperatures

Question

Quizplus · Accepted Answer

The heaviest and most severe aircraft icing occurs in the cloud at just below freezing temperatures, typically between -10°C to -20°C. At these temperatures, supercooled water droplets freeze on contact with the aircraft, resulting in rapid ice accumulation. In warmer temperatures, the ice may still form but at a slower rate, while in colder temperatures, the droplets may freeze before coming into contact with the aircraft, resulting in lesser icing severity. Outside the cloud, the risk of icing is lower but still exists, particularly in visible moisture such as fog or rain.
