How many PMA's provide power to the FBW system?

• A. 1
• B. 2
• C. 3
• D. 4

Answer: (B)

The Fly-By-Wire (FBW) system in the Dassault Falcon 7X is designed with high reliability and safety in mind, which is a critical aspect of modern aircraft design. In this system, two Power Management Units (PMUs) are responsible for providing electrical power to ensure that the FBW controls operate effectively under various conditions. Having two PMUs means that if one unit were to fail or experience an issue, the other can continue to supply power, thus enhancing safety through redundancy. This redundancy is crucial for critical systems like FBW, as it ensures continuous operation and helps prevent loss of control in-flight. The other options suggest fewer or more PMUs, which would not accurately reflect the design principles of safety and redundancy integral to modern aircraft systems. Therefore, the correct understanding is that the FBW system is powered by two PMUs, providing a balanced approach to reliability and operational capability.
