Recirculation fans in the air conditioning system direct filtered cabin air to which area?

Correct! Wrong!

In normal operation which bleed air source has priority?

Correct! Wrong!

Air is normally bled from the intermediate pressure stage (IP) of engine’s high-pressure (HP) compressor to minimize fuel penalty.

Correct! Wrong!

In automatic mode, the crossbleed valve opens when the system is using APU bleed air.

Correct! Wrong!

What happens when pressure and temperature are not sufficient to supply the corresponding engine bleed valve?

Correct! Wrong!

The pneumatic system supplies high-pressure air for air conditioning, engine starting, wing anti-icing, water pressurization and hydraulic reservoir pressurization.

Correct! Wrong!

A check valve near the crossbleed duct protects the APU, when bleed air comes from another source.

Correct! Wrong!

If APU Bleed is ON and the crossbleed valve is shut, the Engine bleed valve 2 remains open.

Correct! Wrong!

Air bleed from the engines is:

Correct! Wrong!

When engine and wing anti-ice are in use, and a BMC detects a bleed leak:

Correct! Wrong!

The overheat detection system uses a single loop for:

Correct! Wrong!

In flight if the air pressure is insufficient even with the HP valve open:

Correct! Wrong!

The lavatory/galley extract fan operates:

Correct! Wrong!

Each bleed valve is electrically operated and controlled by its associated BMC (Bleed Monitoring Computer).

Correct! Wrong!

Each bleed valve is pneumatically operated and controlled electrically by its associated BMC.

If a Bleed Monitoring Computer (BMC) fails:

Correct! Wrong!

The APU BLEED pb-sw controls the APU bleed valve. When the flight crew selects ON with the pushbutton, APU bleed air supplies the pneumatic system, if the APU speed is _____. This opens the crossbleed valve and closes the engine bleed automatically.

Correct! Wrong!

If bleed air is being supplied by the APU or if one pack fails, pack flow will go to _____ rate.

Correct! Wrong!

BMC2 takes over all monitoring functions if BMC1 fails except for:

Correct! Wrong!

Engine Bleed Indications – The Precooler outlet temperature is normally in green. It becomes amber, if:

Correct! Wrong!

During Normal operation, when would the HP valve open?

Correct! Wrong!

A leak detection system detects any overheating in the vicinity of hot air ducts.

Correct! Wrong!

If BMC1 (Bleed Monitoring Computer) fails BMC2 takes over all monitoring functions except:

Correct! Wrong!

Bleed air normally comes from the _____ of the engine.

Correct! Wrong!

The pressure regulating and shutoff valve will close if _____ pressure is _____ or _____ airflow occurs.

Correct! Wrong!

With the loss of pneumatic system pressure, the engine bleed valve will:

Correct! Wrong!

Temperature regulation is controlled by:

Correct! Wrong!

When selected ON, the APU bleed air will:

Correct! Wrong!

For what condition will the APU BLEED FAULT light illuminate amber?

Correct! Wrong!

An ECAM caution will also appear.

Temperature regulation is achieved by the precooler which regulates and limits the temperature at:

Correct! Wrong!

The crossbleed valve has three electric motors: one for the automatic mode, one for the manual mode and one for the degraded mode.

Correct! Wrong!

The crossbleed valve has two electric motors: one for the automatic mode and one for the manual mode.
