In the event of total hydraulic failure, how are the primary flight controls operated?

In the event of total hydraulic failure on the Dassault Falcon 2000LXS, the primary flight controls are operated manually. This means that pilots can directly control the aircraft's flight surfaces without reliance on hydraulic assistance, which is crucial during such an emergency situation. Manual operation allows for basic control of the aircraft, ensuring that pilots retain the ability to maneuver and maintain control, even when the primary hydraulic systems are compromised.

Other options, such as using auxiliary electrical systems, backup hydraulic systems, or automatic controls, would not apply in this scenario, as a total hydraulic failure implies that no hydraulic systems are functioning, leaving manual control as the only viable means for the pilots to operate the aircraft safely. Understanding the manual operation of flight controls is important for flight safety and for successfully managing emergencies.
