A320: Pneumatics & Air Conditioning | Quiz - Pilot George, L3 Airline Academy (CTC Aviation) Cadet Blog

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!

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

At low thrust settings.

With pilot intervention on the overhead panel.

At TOGA power.

When IP pressure is insufficient for the demand.

Correct!

Incorrect!

Q14357 What is lost with the failure of BMC1?

ENG BLEED LEAD warnings for ENG2 and APU BLEED LEAK warning

Nothing, BMC2 takes over.

APU BLEED LEAK warning only.

ENG BLEED LEAD warnings for ENG1 and APU BLEED LEAK warning

Correct!

Incorrect!

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

They partially close.

They fully open.

They fully close.

Control over them is lost.

Correct!

Incorrect!

Q14385 [RAM AIR] What is the outflow value position less than 1 PSI of differential pressure?

Opens to 50%

Closes.

Remains Normal

Opens fully.

Correct!

Incorrect!

Q14377 What conditions could cause the Pack Flow to be Higher than that Selected on the Overhead Panel?

Single-pack operation and APU is unavailable.

Single-pack operation, APU is supplying bleed air, Temperature demand can not be satisfied with LO flow selected.

Cooling of pack systems is required.

On the ground with both engines running.

Correct!

Incorrect!

Q14373 What controls the Packs and Trim Air Values?

Fan blade air.

The Trim Air Values.

The Air Conditioning System Controllers (ACSCs)

The Bleed Value.

Correct!

Incorrect!

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

The Air Conditioning System is stuck at the present temperatres.

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

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.

Correct!

Incorrect!

Q14366 What happens if a leak is detected when the XBLEED switch is in the AUTO position?

The value closes.

Nothing happens.

The value closes. The exception is engine start.

The value opens to allow APU to assist the packs in fullfilling system demand.

Correct!

Incorrect!

Q14374 What happens to the air conditioning system during Engine Start?

Packs are turn off to ensure optimum bleed air for engine start.

Pack flow is reduced to ensure optimum bleed air for engine start.

The cabin goes quiet.

It operates normally.

Correct!

Incorrect!

Q14383 What Limitation(s) apply to the Opening of the Ram Air Valve?

Speed

Differential Pressure

Speed and Altitude

Ditching not selected on

Correct!

Incorrect!

Q14359 On the SD, when/how is GND displayed?

In all flight phases, in white.

When on the ground, in green.

In all flight phases, in green.

When on the ground, in white.

Correct!

Incorrect!

Q14361 How is Bleed Air Pressure regulated?

The ACSCs

The Trim Air Values.

The Pack Flow Control Values.

The Bleed Value.

Correct!

Incorrect!

Q14376 When does the Ram Air Inlet Flap close?

<100' RA

Air Conditioning System Fault.

Landing Gear retraction/extension

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

Correct!

Incorrect!

Q14378 The Zone Temperature Controllers can be Set to what Range of temps?

COLD = 18 degrees, 12 o'clock = 24 degrees, HOT = 30 degrees.

COLD = 15 degrees, 12 o'clock = 20 degrees, HOT = 35 degrees.

COLD = 10 degrees, 12 o'clock = 21 degrees, HOT = 30 degrees.

COLD = 9 degrees, 12 o'clock = 22 degrees, HOT = 30 degrees.

Correct!

Incorrect!

Q14369 Is WAI (Wing Anti Ice) allowed if only one bleed system is in operation?

Yes.

Yes but PACK FLOW selector must be set to LO, due to precooler performance.

Yes but to ensure precooler performance one pack must be switched off when using anti-ice.

No, precooler performance is degraded.

Correct!

Incorrect!
