The flight controls system for the Gulfstream V is hydraulically powered, providing boost to mechanical linkages to overcome aerodynamic forces associated with high speed flight. Tandem type hydraulic actuators, receiving hydraulic fluid under pressure from two independent systems (Left and Right hydraulic systems), are used to move the flight control surfaces. Both hydraulic systems maintain a system pressure of 3000 psi. Loss of system pressure by one hydraulic system has no effect on operation of the flight controls, as the remaining system is capable of maintaining actuator load capacity. In the event of total loss of hydraulic pressure in both hydraulic systems, the primary flight controls revert to manual operation.
