What is one benefit of using glycol-based de-icing fluids?

Glycol-based de-icing fluids are specifically formulated to provide a lower freezing point compared to water, which is a critical property for effective de-icing. This characteristic allows these fluids to remain effective even in severe cold conditions, ensuring that ice does not form on aircraft surfaces or roadways. The ability to lower the freezing point helps in preventing ice accumulation and ensures safer operations during winter weather.

The other characteristics of glycol-based fluids, such as cost, evaporation rate, and biodegradability, do not directly contribute to their primary function as de-icers. While some alternatives may focus on being more cost-effective or environmentally friendly, the essential attribute of glycol-based fluids that specifically aids in de-icing performance is their ability to reduce the freezing point of water. This makes them an effective choice for maintaining safety and operational efficiency in icy conditions.
