WebNov 14, 2014 · Aviation has traditionally classified icing as rime vs. clear icing. This classification, however, is just a measure of how much air is trapped in the ice and how quickly it froze. So there is only an indirect relationship to icing severity. It actually makes more sense to look at the kind of ingredients that exist within the cloud. WebClear icing conditions exist more often in an environment with warmer temperatures, higher liquid water contents, and larger droplets. Clear ice forms when only a small portion of the drop freezes immediately while the remaining unfrozen portion flows or smears over the aircraft surface and gradually freezes.
