What are the temperature ranges for ice formation categorized as mixed icing?

Mixed icing occurs in a specific temperature range where both clear and rime icing can develop simultaneously. This phenomenon typically occurs when the atmospheric conditions are conducive to the presence of supercooled water droplets.

In this instance, the correct temperature range for mixed icing is from -10 to -15 degrees Celsius. In this range, the conditions allow for the coexistence of larger supercooled water droplets, which tend to produce clear icing, and smaller droplets, which can result in rime icing. Understanding this range is critical for pilots, as encountering mixed icing can significantly affect aircraft performance and handling.

Other temperature ranges may not present the right conditions for mixed icing. For example, warmer temperatures closer to zero Celsius tend to promote more of a clear icing scenario, while colder temperatures might lead to rime icing. Recognizing the specific temperature involved in mixed icing helps pilots make informed decisions regarding icing hazards and appropriate responses during flight.
