What is the approved procedure for applying a second coating of anti-icing fluid?

• A. Apply directly over the existing fluid
• B. De-ice the airplane before applying another coating
• C. Wait for the first coat to dry before applying
• D. Apply only if conditions are ideal

Answer: (B)

The approved procedure for applying a second coating of anti-icing fluid is to de-ice the airplane before applying another coating. This procedure is crucial because anti-icing fluids work best on a clean, uncontaminated surface. If the first layer of fluid is allowed to dry or is topped without addressing any ice or snow that may have formed, the new application may not adhere properly or may trap contaminants, leading to ineffective de-icing capabilities. De-icing involves removing any accumulation of ice or snow to ensure that the anti-icing fluid can form an effective barrier against further accumulation. This step is essential for maintaining the aircraft's safety and performance when flying in winter conditions. Properly adhering to this procedure ensures that the anti-icing layer remains functional and provides optimal protection from ice build-up on critical surface areas.
