Type I de-icing fluids are typically dyed for identification. What color is standard?

• A. Orange
• B. Blue
• C. Green
• D. Yellow

Answer: (A)

Color identification of de-icing fluids is used to distinguish the product type at a glance. Type I is a low-viscosity de-icer used to remove existing ice and prepare the surface for anti-icing. It is dyed orange so it stands out clearly on ice, on the aircraft, and in runoff. This bright color helps ground crews ensure the correct fluid is used in the right sequence and prevents mix-ups with other fluids, which supports safety and proper holdover decisions. Other colors like blue, green, or yellow aren’t the standard for Type I, though different regions or suppliers may use different color schemes for other fluids; orange is the recognized standard for Type I.
