How many fuel sump drains are installed on the aircraft?

The Dassault Falcon 2000LXS is designed with a specific number of fuel sump drains, which play a crucial role in maintaining fuel quality and safety. The correct answer is that the aircraft has 10 fuel sump drains. These drains are strategically placed to allow for the removal of water and contaminants that may accumulate in the fuel tanks. Regular checks of these drains are an essential part of pre-flight procedures to ensure that the fuel system is free from any potential hazards that could compromise the aircraft's performance.

This number reflects the manufacturer's emphasis on safety and operational efficiency, as having multiple sump drains provides better coverage for fuel system maintenance. The other choices do not accurately represent the set design features of the Falcon 2000LXS, either falling short of or exceeding the actual number needed to maintain optimal fuel quality.
