What must be considered when using the Hydraulic Backup Pump?

• A. It cannot be used above 10,000ft
• B. Avoid continuous use above 15,000ft
• C. It is not allowed during takeoff
• D. Use only during emergencies

Answer: (B)

When utilizing the Hydraulic Backup Pump in the Dassault Falcon 7X, one critical consideration is avoiding continuous use above 15,000 feet. This limitation is imposed due to the hydraulic system's performance characteristics, which can be affected by altitude. At higher altitudes, the ambient air pressure decreases, which can impact the efficiency and functionality of hydraulic systems. Thus, using the backup pump continuously above this altitude may lead to reduced effectiveness and potential failure. It’s important for pilots and operators to be aware of this threshold to ensure safe operation and reliability of the aircraft's hydraulic systems. While the other options touch on various operational guidelines, they do not accurately reflect the specific altitude restrictions necessary for safe hydraulic backup pump usage.
