De-icing is the process of removing ice or snow from surfaces, especially on roads, runways, and vehicles. This is crucial during winter months when ice can create hazardous conditions. Common methods include using salt, sand, or specialized de-icing fluids that lower the freezing point of water, making it easier to melt the ice. In aviation, de-icing is vital for ensuring the safety of flights. Airports use heated fluids to spray on aircraft, preventing ice from forming on wings and other critical parts. This helps maintain the aircraft's performance and ensures a safe takeoff, especially in regions prone to winter weather, like the Midwest or Canada.
