What do the HYD system gauges on the sides of the fuselage indicate?
Reservoir fluid level
Pumps are regulated to maintain HYD system pressure at ___?
T/F: FWD priority valve shuts off pressure to the gun drive, refueling probe, and the main landing gear?
In the event of a complete loss of hydraulic pressure, the flight controls are driven by:
they cease to function
Which cautions would indicate a leak in the HYD 2B circuit?
The HYD 2A caution will come on and go out and a HYD 2B caution will come on
When do the iso valves close?
On every flight
What is the purpose of the switch valves?
Enables the 2 HYD system to backup one another in the event one of them fails
Which combination of hydraulic failures is most detrimental to the control of the aircraft?
HYD 1A and HYD 2B
What is the purpose of the heat exchanger?
Cool HYD fluid
Which cautions indicate a number 2 HYD pump failure?
HYD 2A and HYD 2B
Each stab is plumbed such that any one of how many HYD circuits could power the actuators?
T/F: Provided that there's not a leak in the isolated HYD 2B system, it is recommended that the HYD isolate ORIDE switch be held in the ORIDE position for 10 sec after APU ACCUM caution is removed to ensure full charge
What is the purpose of the isolation valves?
To lessen the load on pump 2
What is the purpose of the HYD iso ORIDE switch?
To recharge APU ACCUM in flight
T/F: An APU ACCUM caution indicates that HYD APU pressure is high?
