Airbus A330 - Pneumatic

The Engine Bleed system is controlled and monitored by:

Two EBS computers, one primary and one stand-by.

One dedicated Bleed Monitoring Computer (BMC) for each engine.

An Engine Bleed System (EBS) computer.

Correct! Wrong!

The X-Bleed Valve is AUTO. It will open automatically when the air is coming from:

ASU.

Engines.

APU.

Correct! Wrong!

On ground when using an Air Supply Unit (ASU) to have pneumatic pressure on both sides:

The X-Bleed selector must be OPEN and both packs will go On.

The X-Bleed selector must be AUTO and both packs will go On.

The X-Bleed selector must be OPEN and both packs will go Off.

Correct! Wrong!

In flight, when APU Bleed Valve is opened, if a wing leak is detected, Engine Bleed Valve and HP Valve on related side close and:

Wing anti-ice must not be used.

APU Bleed Valve closes automatically if the wing leak concern the left wing.

APU Bleed Valve closes automatically if the wing leak concern the right wing.

Correct! Wrong!

If an engine bleed pylon leak is detected, the bleed valve on the same side closes, the X-Bleed valve receives a closure signal, and:

Wing anti-ice may be selected.

OFF light appears in the ENG BLEED pb associated with the closed Engine Bleed Valve.

A FAULT light appears only in the ENG BLEED pb associated with the pylon leak and wing anti-ice must not be selected.

Correct! Wrong!

When the APU Bleed is ON and the X-Bleed Valve is in AUTO:

Only ENG 1 Bleed Valve is automatically closed.

Both Engine Bleed Valves are automatically closed.

Only ENG 2 Bleed Valve is automatically closed.

Correct! Wrong!

The temperature regulation of bleed air is achieved by a precooler, that is mounted downstream of the bleed valve. The precooler is an air-to-air heat exchanger, which uses cooling air that is bled from the engine fan, to regulate the temperature to 200 deg.C.

True.

False.

Correct! Wrong!

When AIR ENG 1 BLEED FAULT appears on ECAM:

FAULT light goes out if ENG BLEED pb is pushed off with failure still present.

FAULT light in ENG BLEED pb remains on as long as the failure is present.

Amber FAULT light and white OFF light appear in ENG BLEED pb.

Correct! Wrong!

On ECAM BLEED page the 'GND' message is displayed in white. What does it mean?

The aircraft is on ground. It is not displayed in flight.

External air may be connected, turns amber if pressure is out of limit.

It is on stand by, turns green when external air is connected.

Correct! Wrong!

In flight, with Wing anti-ice On, if there is a wing leak detection:

The X-Bleed Valve opens automatically to allow normal de-icing.

The Wing anti-ice is automatically stopped.

Only one wing will be de-iced.

Correct! Wrong!

X-BLEED is actuated by 2 electric motors:

One is supplied by AC generation, the other is supplied by DC generation.

One is MAIN, the other one is STBY.

One for the automatic mode, the other for the manual mode.

Correct! Wrong!

Bleed air supply from the APU:

Is controlled by the APU Bleed Valve and is available on ground and in flight.

Is not available for air conditioning.

Is not available in flight.

Correct! Wrong!

Each BMC (Bleed Monitoring Computer) is provided with bleed pressure, temperature and valve position information, and is interconnected to other systems involved with the bleed system and the other BMC.

True.

False.

Correct! Wrong!

Which of the following statements is true?

APU bleed is controlled and monitored either by BMC 1 or BMC 2.

Each engine bleed system is controlled and monitored by one Bleed Monitoring Computer (BMC).

Each engine bleed is pneumatically controlled and electrically operated.

Correct! Wrong!

The pneumatic system supplies high pressure air:

Only for the hydraulic and water reservoir pressurization.

For air conditioning, engine starting, wing anti-ice, as well as for hydraulic and water reservoir pressurization.

Only for air conditioning, engine starting, and wing anti-ice.

Correct! Wrong!

It also supplies air to Pack bay ventilation turbofan actuation, Cargo heating and Fuel Tank Inerting System (FTIS).

The APU Bleed Valve has the priority on the ENG Bleed Valves:

Only for engines start up.

False.

True.

Correct! Wrong!

Air is supplied to the aircraft’s pneumatic system via one HP ground connector only. The crossbleed valve has to be opened manually to provide air for both sides.

False.

True.

Correct! Wrong!

Air is supplied to the aircraft’s pneumatic system via two HP ground connectors. The crossbleed valve has to be opened manually to provide air for both sides.

The opening of the APU Bleed Valve when X-Bleed is set on AUTO, causes:

The opening of the X-Bleed Valve.

All statements are true.

The closing of the ENG Bleed Valves.

Correct! Wrong!

In case of APU leak signal:

The X-Bleed Valve must be closed manually as soon as possible.

The APU Bleed Valve must be closed manually as soon as possible.

The APU Bleed Valve closes automatically.

Correct! Wrong!
