While I have tried to ensure the information in this quiz is accurate, it is your own responsibility to check it against your airline / manufacturer manuals. With that said, if you spot any obvious errors then please let me know the question number and I'll aim to put it right!

Q14370 What should you NOT do if GD LP Air is connected to the pneumatics system?

Open the XBLEED value.

Close off the XBLEED value.

Correct!

Incorrect!

Q14373 What controls the Packs and Trim Air Values?

The Bleed Value.

Fan blade air.

The Air Conditioning System Controllers (ACSCs)

The Trim Air Values.

Correct!

Incorrect!

Q14364 What temperature is bleed air regulated to within the pre-cooler?

Room temperature

100 degrees

50 degrees

200 degrees

Correct!

Incorrect!

Q14368 When does the bleed air temperature / pressures box turn amber on the SD?

High Pressure & High Temperatures.

Temperatures outside of predefined limits

High/Low Pressure & High/Low Temperature

Overheat only.

Correct!

Incorrect!

Q14376 When does the Ram Air Inlet Flap close?

Air Conditioning System Fault.

During takeoff when land gear struts are compressed. During landing when speeds are above 70 knots (Re-opens 20sec after< 70 knots).

Landing Gear retraction/extension

<100' RA

Correct!

Incorrect!

Q14380 What happens if an ACSC has a Double LANE failure?

The Air Conditioning System is stuck at the present temperatres.

Loss of the pack on that side, hot air value closes (ACSC1 only), system specific trim air values close.

The Air Conditioning System Fails and Trim Air Values are lost.

No degration in operation. The other ACSC can handle the system.

Correct!

Incorrect!

Q14367 In normal operation which bleed air source has priority?

APU

Engine Bleed

Ground Air

RAM Air

Correct!

Incorrect!

Q14358 If a BMC fails, what happens to the bleed values?

They fully open.

They partially close.

Control over them is lost.

They fully close.

Correct!

On the ground with both engines running.

Correct!

Incorrect!

Q14360 During Normal operation, when would the HP value open?

With pilot intervention on the overhead panel.

At low thrust settings.

When IP pressure is insufficient for the demand.

Correct!

Incorrect!

Q14371 What should you NOT do if HP Air Starter is connected to the pneumatics system?

Close the XBLEED value.

Use Engine Bleed.

Use GP LP Air.
