De-icing is the process of removing ice or snow from surfaces, especially on roads, vehicles, and aircraft. This is crucial during winter months when icy conditions can make travel dangerous. Common methods include using salt, sand, or special chemicals that lower the freezing point of water, helping to melt the ice. In aviation, de-icing is vital for ensuring the safety of flights. Airports use heated fluids to spray aircraft wings and other surfaces, preventing ice buildup that can affect performance. Proper de-icing helps maintain safe flying conditions and keeps passengers and crew secure during winter weather.
