What does the OFF position do for the Bleed Switches?

• A. HP/LP valves remain operational
• B. HP and LP valves closed
• C. Only HP valves remain operational
• D. Only LP valves remain operational

Answer: (B)

The OFF position for the Bleed Switches in the Dassault Falcon 7X specifically closes both the High-Pressure (HP) and Low-Pressure (LP) valves. This action effectively isolates the bleed air system from the engine bleed air sources, preventing any bleed air from being utilized for cabin pressurization or environmental control systems. Closing both valves ensures that the pressurized air is not diverted, which is crucial during certain phases of flight or maintenance procedures to maintain system integrity and performance. When the bleed switches are OFF, it ensures that the aircraft systems relying on bleed air are not inadvertently affected, which can be important for safety and efficacy during operation. The operational state of the HP and LP valves is important in the context of managing aircraft systems, and understanding when these are closed provides clarity on how the aircraft manages bleed air utilization.
