A

High air pressure

2
Q

Under normal conditions, it is possible to control temperature in all areas except the

A

Forward cargo compartment

3
Q

If the APU is supplying bleed air or one PACK fails, ______ flow is delivered regardless of pack flow selector position

A

HI

4
Q

If Pack Flow is selected to LO and temperature demand cannot be satisfied, the pack reverts to _____flow

A

NORM

5
Q

What happens if a zone cooling demand is not met due to low bleed pressure

A

Engine idle is automatically increased

6
Q

The PACK valves close when the ENG MODE SEL switch is placed to IGN/START before engine start. When will they reopen?

A

30 seconds after first engine start if second engine start has not been initiated

7
Q

Hot _____ air from the pneumatic system is used to maintain desired zone temperature

A

Trim

8
Q

Using external conditioned ground air simultaneously with airplane pack air is

A

Prohibited

9
Q

The HOT AIR FAULT light illuminates amber when a duct _____ is detected

A

Overheat

10
Q

What happens to cabin zone inlet duct temperature if the lav/galley extract fan fails?

A

Cabin zone inlet duct temperature is fixed at 59F

11
Q

If the primary PACK controller channel fails, the secondary pack controller channel automatically takes over and

A

Pack flow is fixed at pre-failure setting

12
Q

What occurs if both PACK controller channels fail?

A

PACK outlet temp goes to a set temperature range by the pack anti-ice valve.

13
Q

If a zone controller primary channel faults occurs, what happens to the air conditioning system?

A

The flight deck is controlled to 76 degrees F by pack 1 and the cabin forward and aft zones are controlled to 76 degrees F by pack 2

14
Q

ALTN MODE displays in green on the ECAM COND page when a

A

Primary zone controller fault is detected

15
Q

If both zone controller channels fail,

A

The related ECAM information is not displayed, and message PACK REG appears.

16
Q

What pilot action is required with loss of primary and secondary zone controller channels

A

None. System automatically goes to a fixed temperature

17
Q

Selecting the RAM AIR switch ON, opens the ram air inlet valve provided the _____ switch is not selected ON

A

DITCHING

18
Q

When will the avionics ventilation system be in the closed configuration while on the ground?

A

Cold Skin temperatures

19
Q

You are doing the walk around at ORD in January and notice both the inlet and extract valves are closed. You should

A

Continue the walk around; this is normal.

20
Q

The avionics ventilation system provides cooling for all the following except the

A

Cabin entertainment system

21
Q

The Air Conditioning RAM AIR switch is selected to ON, the differential pressure is less than 1 PSI. The ram air inlet opens and the outflow valve

A

Opens to approximately 50 percent if the cabin pressure MODE SEL switch is in AUTO.

22
Q

While pre-flighting, you hear a horn in the nose wheel well. Since the APU is NOT running, this may indicate a

A

Duct overheat in the avionics ventilation system

23
Q

During normal operation, the air conditioning system temperature is regulated by

A

One zone controller and two pack controllers
