Q14363 How is Bleed Air Temperature regulated?

Fan blade air.

Trim air.

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

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

Correct!

Incorrect!

Q14362 What is the typical Bleed Air Pressure?

45 psi.

Plus or minus 65 psi.

65 psi plus or minus 5.

Correct!

Incorrect!

Q14379 What happens if an ACSC has a LANE failure?

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

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

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

The Air Conditioning System is stuck at the present temperatres.

Correct!

Incorrect!

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

Close the XBLEED value.

Use GP LP Air.

Use Engine Bleed.

Use bleed air from the APU BLEED at the same time to prevent any adverse effect on the Bleed Air System.

Correct!

Incorrect!

Q14375 What happens when a Duct Overheat occurs in the wings?

That duct is isolated.

HOT AIR FAULT light illuminates on the overhead panel and duct is isolated.

The respective pack must be switched off.

LVL 1 Caution only.

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!

Q14356 What happens if BMC fails?

Associated bleed value closed automatically.

Leak detection is lost.

ECAM warnings are lost.

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

Incorrect!

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

When on the ground, in white.

In all flight phases, in white.

When on the ground, in green.

In all flight phases, in green.

Correct!

Incorrect!

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

Control over them is lost.

They fully close.

They partially close.

They fully open.

Correct!

Incorrect!

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

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

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

No, precooler performance is degraded.

Yes.

Correct!

Incorrect!

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