120% of normal

The pack flow control valve closes automatically in case of:

Pack overheating, engine starting, or operation of the fire or ditching pushbutton pressed

Trim air valve failure

The optimized temperature regulation of the corresponding zone is lost

There are how many trim air valves?

3 - one for the cockpit and two for the cabin

During landing run, ram air inlet flaps open when the speed is less than:

70 knots ( after a 20 sec delay)

When APU is supplying the packs, they send a demand signal to increase airflow when a zone temperature can’t be satisfied:

To the APU ECB

When the ditching switch is selected ON, it sends a closure signal to:

Both (Outflow valve) and (Ram air inlet, ventilation extract valves and the pack flow control valves) are correct

In flight, with pressure controller 1 in use, if it fails:

Transfers automatically to controller 2

In normal operation, pressurization is:

Fully automatic

The outflow valve is powered by:

One of three electric motors

During ground operation, the outflow valve is:

Fully open

To see the position of the outflow valve, it is necessary to call ECAM:

PRESS Page

Two identical, independent, pressurization controllers are used for system control:

One controller active, one in standby

Which controller generates excess cabin altitude and pressure outputs for ECAM indication in manual mode:

N°1

When Ram Air pb is set to ON, the outflow valve will open 50% when delta P is:

< 1 psi

The purpose of the safety valves is to avoid:

Both (Excessive positive pressure differential) and (excessive negative pressure differential) are correct

The safety valves are operated:

Pneumatically

When landing elevation is set to AUTO, the landing elevation is sent to the controller from:

FMGC

When Mode SEL is set to MANUAL, the outflow valve is controlled by signals sent via controller 1 or 2:

False

On ECAM CAB PRESS page, the outflow valve indicator changes to amber if:

The valve opens more than 95% during flight

On ECAM CAB PRESS page, the safety valve indication changes to amber if:

Either valve is not closed

On ECAM CAB PRESS page the cabin altitude indicator changes to red when the cabin altitude is:

> 9, 550 feet

Following a SYS 1 fault:

System 2 takes over automatically without crew action

Cabin pressurization starts at:

Take-off

The pressure safety valves open at:

8.6 psi above ambient pressure

In automatic mode, cabin pressurization is optimized by using information from:

FMGS landing field elev, dest. QNH and static pressure information

During normal flight and with skin temp. below 35 °C, the avionics ventilation system controls the temperature of the cooling air by:

Passing air through a skin heat exchanger

When the RAM AIR pushbutton is set to ON, the emergency ram air inlet valve will open:
