Hazard of ice crystals

Icing on WingsWith 0 comments

Clouds at temperatures between 0 and -40C contain a mixture of ice crystals and super-cooled water. At colder temperatures, ice crystals prevail. Super-cooled water is responsible for the threat of aircraft structural icing, but at lower temperatures, this threat decreases. Because of the lack of super-cooled water, icing, other that of light intensity, is unlikely

Historically, aviators have been concerned with icing that occurs when super-cooled liquid water freezes upon contact with an airframe at temperatures below 0C. Generally at very cold temperatures, the amount of super-cooled water present in a cloud decreases. At temperatures below -40C, it is generally accepted that super-cooled water does not exist in clouds, and
