a. automatically close both green system FSOV
- The A330 hydraulic system is composed of:
a. three hydraulic systems sharing the same pressure source
b. three fully independent systems working simultaneously
c. three hydraulic systems which interchange hydraulic fluid
b. three fully independent systems working simultaneously
- In the event of low hydraulic pressure, the priority valve and pressure maintaining valves give priority to primary flight controls and brakes. The pilot:
a. controls the priority valve from the HYD panel
b. cannot control the priority valves, but monitors their operation on the HYD ECAM page
c. can neither control nor monitor the priority valves (automatic operation)
c. can neither control nor monitor the priority valves (automatic operation)
- Leak measurement valves pushbuttons on maintenance panel:
a. are for maintenance purposes and ground operation only
b. may be used by the crew to isolate flight controls during flight
c. may be used to isolate heavy users
a. are for maintenance purposes and ground operation only
- On the HYD ECAM page, if the pilot sees the BLUE hydraulic system label displayed amber:
a. hydraulic system overheat
b. hydraulic system overpressure
c. hydraulic pressure is lower than normal
c. hydraulic pressure is lower than normal
- What is the difference when we compare the blue electric HYD pumps to the green and yellow electric pumps?
a. The blue electric pump has a higher flow
b. The blue electric pump has a higher pressure
c. The blue electric pump has no automatic operation
c. The blue electric pump has no automatic operation
- In the HYD panel, the yellow electric pump pushbutton is in the OFF position (OFF light illuminated). The aircraft is in flight and the FLAP handle is at 2. According to these indications:
a. If yellow engine pump fails, the yellow electric pump will start, even if set to OFF.
b. If engine #2 fails, the HSMU will automatically operate the yellow electric pump and restore yellow pressure.
c. If engine #2 fails, the HSMU will not automatically operate the yellow electric pump.
c. If engine #2 fails, the HSMU will not automatically operate the yellow electric pump.
- During landing the gear retraction, engine 1 has failed and Green electric pump is automatically activated. How will it stop?
a. The Green electric pump spring loaded switch must be pressed.
b. The Green electric pump will stop automatically after 25 seconds.
c. The ENG 1 pump pushbutton must be selected OFF to stop both pumps.
b. The Green electric pump will stop automatically after 25 seconds.
- If the pilot pushes the RAT MAN ON pb:
a. the RAT will extend in flight only
b. the RAT will extend at any time
c. the RAT will not extend as the HSMU has not detected a Green + Blue reservoir low level
b. the RAT will extend at any time
- Crew wants to re-established the blue hydraulic system after shutdown due to overheat. When established on final approach, how does the crew determine whether or not the overheat condition still exists?
a. Fault light in pushbutton must be checked by turning blue ENG 2 pb to ON.
b. Fault light in blue ENG 2 pb will only go out with the pb OFF and OVHT no longer exists. OVHT remains on HYD ECAM page as reminder.
c. When overheat no longer exists the fault light will go out with blue ENG 2 pb ON or OFF, and OVHT indication no longer appears on HYD ECAM page.
c. When overheat no longer exists the fault light will go out with blue ENG 2 pb ON or OFF, and OVHT indication no longer appears on HYD ECAM page.
- When the BLUE engine pump pb fault light illuminate due to low bleed air pressure on the BLUE reservoir. Which one of the following statements is true?
a. The BLUE electric pump must be set to ON to recover the system.
b. The BLUE system cannot be restore for approach.
