Q14373 What controls the Packs and Trim Air Values?

The Bleed Value.

The Air Conditioning System Controllers (ACSCs)

Fan blade air.

The Trim Air Values.

Correct!

Incorrect!

Q14363 How is Bleed Air Temperature regulated?

Through the use of pre-cooler, downstream of the bleed value.

Fan blade air.

Trim air.

Through the use of a pre-cooler upstread of the bleed value.

Correct!

Incorrect!

Q14356 What happens if BMC fails?

The adjacent BMC takes over the monitoring of the bleed system.

ECAM warnings are lost.

Associated bleed value closed automatically.

Leak detection is lost.

Correct!

Incorrect!

Q14376 When does the Ram Air Inlet Flap close?

Air Conditioning System Fault.

<100' RA

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

Correct!

Incorrect!

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

Differential Pressure

Speed

Speed and Altitude

Ditching not selected on

Correct!

Incorrect!

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

The cabin goes quiet.

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

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

It operates normally.

Correct!

Incorrect!

Q14365 With the XBLEED switch in AUTO, what determines XBLEED value position?

Loss of Bleed Air from both.

The presence of APU bleed air, which when present opens the value.

Total loss of Bleed air.

The presence of APU bleed air, which when present closes the value.

Correct!

Incorrect!

Q14361 How is Bleed Air Pressure regulated?

The Pack Flow Control Values.

The Trim Air Values.

The Bleed Value.

The ACSCs

Correct!

Incorrect!

Q14381 When does a Pack Overheat FAULT light, (on OHP) extinguish?

When the heating condition ceases.

When pack flow is reduced on the overhead air conditioning panel.

On engine shutdown.

When the pack is turned off.

Correct!

Incorrect!

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

The value closes.

The value closes. The exception is engine start.

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

Nothing happens.

Correct!

Incorrect!

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

With pilot intervention on the overhead panel.

At TOGA power.

When IP pressure is insufficient for the demand.

At low thrust settings.

Correct!

Incorrect!

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

200 degrees

Room temperature

50 degrees

100 degrees

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.

Cooling of pack systems is required.

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

On the ground with both engines running.

Correct!

Incorrect!
