What type of hydraulic fluid is used in the Falcon 2000LXS?

The Falcon 2000LXS uses Skydrol as its hydraulic fluid, which is a phosphate ester-based hydraulic fluid specifically designed for use in aviation applications. Skydrol offers a number of advantages that make it highly suitable for aircraft hydraulic systems, including a high flash point, superior fire resistance, and excellent performance over a wide temperature range. Its unique chemical properties help protect hydraulic components from wear and corrosion, ensuring reliable performance in various operational conditions.

Considering the other options, mineral oil-based fluid may not provide the necessary fire resistance and performance characteristics required in aviation hydraulic systems. ATF is often utilized in automotive applications and does not meet the specific requirements for aircraft hydraulic systems. Water-based fluids do not have the robust performance characteristics needed for high-pressure hydraulic systems and are typically used in other, less demanding applications. Hence, Skydrol is the optimal choice for the Falcon 2000LXS due to its tailored properties for aviation needs.
