Correct!
Wrong!
The Blue pump control is supplied by the:
Correct!
Wrong!
Auxiliary Pump pb - The auxiliary pump pb controls operating mode of DC auxiliary pump. AUTO (pb pressed in) runs pump as soon as:
Correct!
Wrong!
The Green pump control is supplied by the:
Correct!
Wrong!
The Hydraulic Auxiliary Pump Switch operates even when batteries master sw is selected OFF.
Correct!
Wrong!
Intensive use discharges the main battery. This switch functions is used only when aircraft is on ground.
Hydraulic Auxiliary Pump Switch - The auxiliary pump switch activates for _____ the auxiliary hydraulic pump and enables it to operate in manual mode.
Correct!
Wrong!
Each hydraulic system is pressurized by an electrical hydraulic pump powered by:
Correct!
Wrong!
On ground, when electrical power is not available, the hydraulic system can be pressurized through a ground hydraulic power unit.
Correct!
Wrong!
The connector for the ground hydraulic power unit is on the Ground Service Panel in the hydraulic bay. A ground switch on the center pedestal enables the supply of energy to the auxiliary pump even if electrical power is not available.
The hydraulic tank is internally divided in two equal compartments (green and blue) by a diaphragm and open in the upper side to allow simultaneous refilling.
Correct!
Wrong!
A compartment baffle avoids fluid splashing and reduces foaming.

In case of LO LVL alert, the hydraulic crossfeed valve remains closed, if it was in closed position and it also remains opened, if it was in opened position.
Correct!
Wrong!
In case of LO LVL alert, the crossfeed valve remains closed, if it was in closed position. It automatically closes, if it was in opened position.
OVHT Lights - The OVHT light comes on amber and the caution message "HYD BLUE (GREEN) OVHT" from FWS appears on EWD associated with a Master Caution and a single Chime, in case of overheat detection. Temperature is more than _____ in the associated drain line of the pump housing.
Correct!
Wrong!
Each compartment has a low level alert triggered when fluid quantity drops below _____
Correct!
Wrong!
The hydraulic tank is a direct air-fluid contact type and is pressurized in flight.
Correct!
Wrong!
The hydraulic tank is a direct air-fluid contact type and is not pressurized.
The blue circuit is fitted with an additional DC driven auxiliary pump. The auxiliary DC electric pump automatically provides hydraulic power to operate the users of the blue system if the ACW pump fails. A momentary ground switch located on the pedestal enables to energize the auxiliary pump manually. This momentary ground switch will operate the DC auxiliary pump for as long as the switch is pushed when the Aircraft BAT toggle sw is OFF and/or:
