What is the temperature range during which mixed icing occurs?

The phenomenon of mixed icing typically occurs at temperatures ranging from -5°C to -15°C. This temperature range is critical because it encompasses the conditions under which supercooled liquid water droplets can coexist with ice crystals in the atmosphere. When the air temperature is within this range, the combination of liquid water droplets and ice can lead to the formation of mixed icing, which poses specific risks to aircraft due to the varied characteristics of these icing conditions.

The conditions for mixed icing are ideal in slightly below freezing temperatures, where some water remains in liquid form due to supercooling, while ice crystals are also present in the environment. Understanding this temperature range is essential for pilots and aviation professionals to make informed decisions regarding flight safety and icing conditions.
