Pressurization Flashcards
IN AUTO, the cabin differential pressure is normally controlled by the
Outflow valve
Automatic transfer of the pressurization controllers occurs after ____ or in case of failure of the _____ controller
Landing, operating
Before takeoff and after landing, the outflow valve should be _____ and the cabin _____
Open, depressurized
The automatic pressurization controller normally uses landing elevation QNH from the _____
FMGC
During decent, the cabin pressure is controlled so that
It reaches landing field pressure just prior to landing
How is the landing field elevation provided to the pressurization system in the case of a divert to an alternate?
The FMGC provides database field elevation when a new destination is entered
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
In the event of failure of both automatic pressure controllers, a third motor provides
Manual operation of the outflow valve
In case of failure of both pressurization controllers, a third motor provides
Manual operation of the outflow valve
Illumination of the MODE SEL FAULT light indicates
A fault is detected in both automatic systems
The cabin safety valve protects against
Excessive differential pressure
When the landing elevation selected with the LDG ELEV selector, the cabin altitude is
Still controlled automatically throughout the outflow valve
How is the cabin altitude controlled in the manual mode?
By toggling the MAN V/S CTL switch
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
What elevation is set on the LDG ELEV selector?
