Airplane Deicing: The How And Why

Did you know that deicing may involve two separate treatments? We didn't until we read what a pilot wrote in this CNN article.

STORY HIGHLIGHTS

* Deicing fluid removes ice and snow; it's made up primarily of a chemical called glycol
* A separate treatment, anti-icing, is used when precipitation is falling to prevent more buildup
