1

IN AUTO, the cabin differential pressure is normally controlled by the

Outflow valve

2

Automatic transfer of the pressurization controllers occurs after ____ or in case of failure of the _____ controller

Landing, operating

3

Before takeoff and after landing, the outflow valve should be _____ and the cabin _____

Open, depressurized

4

The automatic pressurization controller normally uses landing elevation QNH from the _____

FMGC

5

During decent, the cabin pressure is controlled so that

It reaches landing field pressure just prior to landing

6

In the event of a divert to an alternate airport, how is the new landing field elevation normally provided to the automatic pressurization controller?

The FMGC provides database field elevation when a new destination is entered

7

If the airplane returns to the departure airport immediately after takeoff, how is the cabin altitude controlled

Cabin altitude automatically returns to the takeoff elevation

8

In the event of failure of both automatic pressure controllers, a third motor provides

Manual operation of the outflow valve

9

In case of failure of the two automatic controllers, a third back up DC motor is provided for manual operation of the _____ valve

Outflow

10

Illumination of the MODE SEL FAULT light indicates

A fault is detected in both automatic systems

11

The cabin pressurization safety valve protects against

Excessive differential pressure

12

With the MODE SEL AUTO, and the landing elevation set with the LDG ELEV selector, the cabin altitude is

Still controlled automatically throughout the outflow valve

13

How is the cabin altitude controlled in the manual mode?

By toggling the MAN V/S CTL switch

14

How is the pressurization system controlled manually ?

Selecting MODE SEL switch to MAN, and using the MAN V/S CTL switch to control the outflow valve
