De-icing is the process of removing ice or snow from surfaces, particularly on vehicles, roads, and aircraft. This is essential for safety and functionality, especially during winter months when ice can accumulate. Common methods include using heated surfaces, chemical agents like salt, or mechanical tools such as scrapers. In aviation, de-icing is crucial for ensuring that aircraft can operate safely. Ice buildup on wings and other surfaces can affect aerodynamics and performance. Airports often use specialized de-icing fluids that lower the freezing point of water, allowing for effective removal of ice before takeoff.
