Fuel system icing inhibitor use in turbine fuel is set at what percent?

Fuel system icing inhibitor use in turbine fuel is set at what percent?

• A. .7% min to .15%
• B. 0.7% to 0.15%
• C. 0.15% to .7%
• D. 0.7% to 1.5%

Answer: (A)

Fuel system icing inhibitor is added to turbine fuel to prevent ice formation in the fuel lines and filters at low temperatures. The amount is given as a percent by volume. The typical range is about 0.15 percent to 0.70 percent FSII by volume. Keeping the concentration within this band provides anti-icing protection without adversely affecting fuel properties such as viscosity and energy content. If the concentration is too low, icing can occur; if it’s too high, it can impact fuel properties. The option’s endpoints reflect this range, just shown in reverse order.
