Ice Protection Systems are essential technologies used in aircraft to prevent the formation of ice on critical surfaces, such as wings and propellers. Ice can significantly affect an aircraft's performance and safety, making these systems crucial for safe flight in cold weather conditions. They typically use methods like heating elements or chemical de-icing fluids to keep surfaces clear of ice. These systems can be found in various types of aircraft, from small private planes to large commercial jets. For example, the Boeing 737 and Airbus A320 both utilize advanced ice protection technologies to ensure safe operations in icy environments.
