What percentage by volume of icing inhibitor should be added with the PRIST additive?

• A. 0.05 - 0.10%
• B. 0.10 - 0.15%
• C. 0.15 - 0.20%
• D. 0.20 - 0.25%

Answer: (B)

The addition of icing inhibitors to fuel is crucial for ensuring that any water present in the fuel does not form ice, particularly under cold conditions that can affect engine performance. The specified volume percentage of 0.10 - 0.15% for icing inhibitors to be mixed with the PRIST additive is based on industry standards that ensure effective prevention of ice formation in fuel systems. This range is considered optimal for achieving the desired antifreeze properties without causing adverse effects on fuel performance or engine operation. Adding icing inhibitor within this percentage ensures that enough of the chemical is present to prevent ice formation while still maintaining the overall fuel quality. It's essential to adhere to these recommended percentages to ensure safety and reliability in flight operations, particularly in colder environments where icing risk is higher. Other options suggest either insufficient or excessive amounts, which could potentially lead to inadequate protection against icing or unintended consequences in fuel characteristics, emphasizing the importance of using the correct range for effective performance.
