What is the difference between the BLUE ELEC pump and the GREEN or YELLOW ELEC pump?

Correct! Wrong!

Leak measurement valves pb on the Maintenance panel:

Correct! Wrong!

Leak measurement valves are positioned upstream of the primary flight controls. They are used for the leak measurement of each system and may only be closed on ground, by using the LEAK MEASUREMENT VALVES pb on the maintenance panel.

A pump, driven by Engine 2 pressurizes the yellow system. Flight crew can also use a hand pump to pressurize the yellow system, in order to operate the cargo doors when no electrical power is available.

Correct! Wrong!

The GREEN ELEC pump starts automatically:

Correct! Wrong!

There is a BLUE LO AIR PRESS alarm and there is a 'FAULT' indication on BLUE ENG 1 pump pb. Which one of the following statements is true?

Correct! Wrong!

The corresponding hydraulic systems can be pressurized by:

Correct! Wrong!

The BLUE hydraulic system includes operation of:

Correct! Wrong!

The hydraulic reservoirs are pressurized:

Correct! Wrong!

During landing gear retraction, the engine 1 fails and the GREEN ELEC pump is automatically activated. How will it stop?

Correct! Wrong!

If the GREEN hydraulic system is lost:

Correct! Wrong!

The Ram Air Turbine (RAT) deployment is automatically controlled by the HSMU (Hydraulic System Monitoring Unit) when:

Correct! Wrong!

The RAT deploys automatically in the event of an engine failure or a low level in the green and yellow or green and blue reservoirs.

Correct! Wrong!

The RAT deploys automatically in the event of both engine failure or a low level in the green and yellow or green and blue reservoirs.

In the event of hydraulic green low pressure, heavy load users are isolated to give priority to:

Correct! Wrong!

In the event of low hydraulic pressure, a priority valve cuts off hydraulic power to heavy load users (emergency generator, nosewheel steering, landing gear) in order to keep the pressure for normal braking and flight controls.

When the RAT pressurizes the green system, the aileron, elevator, and spoiler servo control operating speeds are reduced.

Correct! Wrong!

With the GREEN hydraulic system lost, the antiskid system is:

Correct! Wrong!

What is the correct statement about the RAT?

Correct! Wrong!

The Airbus A330 hydraulic system has:

Correct! Wrong!

The hydraulic system monitoring unit (HSMU) processes:

Correct! Wrong!

In case of GREEN reservoir LO LEVEL the HSMU (Hydraulic System Monitoring Unit) will:

Correct! Wrong!

What indicates the amber zone on the HYD page?

Correct! Wrong!

After Takeoff, one engine fails prior to the Landing Gear retraction. When the Gear handle is selected 'UP':

Correct! Wrong!

There is no possibility to transfer hydraulic fluid from one system to another.

Correct! Wrong!

An accumulator in each system helps maintain constant pressure by covering transient demands during:

Correct! Wrong!

With a single hydraulic system failure the flight control law is:

Correct! Wrong!

In flight and during approach the FLAP handle is at 2. If an engine 2 failure occurs:
