How does sunlight exposure affect de-icing fluid effectiveness?

• A. It has no impact whatsoever.
• B. Sunlight decreases overall performance.
• C. Sunlight can increase the temperature of the aircraft surfaces, improving fluid performance initially.
• D. Sunlight may damage the fluid's composition.

Answer: (C)

Sunlight exposure can indeed have a beneficial initial effect on the performance of de-icing fluids. When sunlight reaches the aircraft surfaces, it can increase their temperature. This rise in temperature may enhance the ability of the de-icing fluid to effectively melt ice or snow that has accumulated on the aircraft. Warmer surfaces allow the fluid to work more efficiently, leading to improved de-icing processes when applied. In colder conditions or when surfaces remain cold, the fluid may not perform as effectively, as it relies on warmth to facilitate the melting of ice and to properly adhere to the surfaces. Therefore, under certain conditions where sunlight acts to warm the aircraft, the performance of de-icing fluids can be enhanced, making this a significant factor in de-icing operations.
