In case of electrical system failure, which system should be prioritized?

In the event of an electrical system failure in the Dassault Falcon 7X, prioritizing the flight control systems is crucial for maintaining control of the aircraft. The flight control systems are directly responsible for the maneuverability and stability of the aircraft during flight. Without operational flight controls, the ability to safely navigate and land the aircraft is severely compromised.

While emergency lighting, navigation systems, and cabin power systems are important for overall operational safety and passenger comfort, they do not supersede the need to control the aircraft itself. If flight control systems fail, it can lead to catastrophic outcomes, whereas issues with navigation or cabin power, while needing attention, do not directly endanger the aircraft's immediate flight capabilities.

In summary, prioritizing the flight control systems during an electrical failure ensures that the crew can maintain command over the aircraft, allowing them to execute necessary emergency procedures and safely manage the situation.
