What color are Type II fluids typically?

• A. Blue
• B. Green
• C. Light yellow
• D. Orange

Answer: (C)

Color coding helps ground crews quickly identify which fluid is on the aircraft, which is crucial for selecting the right holdover times and application procedure. Type I fluids, used for rapid de-icing, are typically orange. Type II fluids, which form a thicker film to provide anti-icing protection for takeoff, are commonly shown in a light yellow tint to distinguish them from the others. While some regions or suppliers may use different hues, light yellow is a typical color associated with Type II in standard operating practices. This visual cue reduces the risk of mixing up fluids and ensures the correct performance characteristics are applied, though actual holdover times still depend on temperature and concentration.
