What temperature range is indicated for mixed icing?

The indicated temperature range for mixed icing is -8 to -15° C. Mixed icing occurs when both supercooled liquid water and ice crystals are present in the atmosphere, which typically happens in temperatures that typically fall within this range. This is an important consideration for pilots, as mixed icing can be particularly hazardous due to the envelopment of ice on the aircraft's surfaces, leading to increased weight and altered aerodynamics.

In contrast, outside this specific range, you would generally find either clear icing (usually occurring at slightly warmer temperatures when there's more liquid water present) or rime icing (which occurs at colder temperatures below -15° C where the liquid water content is lower and ice crystals perform differently upon impact). Understanding these temperature thresholds is crucial for assessing icing conditions and making informed decisions during flight operations.
