Systems - Pressurization Flashcards
Automatic transfer of the pressurization controllers occurs after ____
or in case of failure of the ____ controller. (FM: 8.20.50.1)
Landing, operating
Before takeoff and after landing, the outflow valve should be ______ and the cabin _____. (FM: 8.20.50.1)
Open, depressurized
The automatic pressurization controller normally uses landing elevation QNH from the ____. (FM: 8.20.50.1)
FMGC
During descent, the cabin pressure is controlled so that (FM: 8.20.50.1)
It reaches landing field pressure just prior to landing.
How is landing field elevation provided to the pressurization system in the case of a divert to an alternate? (FM: 8.20.50.1)
The FMGC provides database elevation when a new destinationis entered.
If the airplane returns to the departure airport immediately after takeoff, how is the cabin altitude controlled? (FM: 8.20.50.1)
Cabin altitude automatically returns to the takeoff elevation.
How is the cabin altitude controlled when in the manual mode?
(FM: 8.20.50.2 )
By toggling the MAN V/S CTL switch.
In case of failure of both pressurization controllers, a third motor provides
(FM: 8.20.50.2 )
Manual operation of the outflow valve.
Illumination of the MODE SEL FAULT light indicates (FM: 8.20.60.1)
A fault is detected in both automatic systems.
The cabin safety valve protects against (FM: 8.20.50.1)
Excessive differential pressure.
What elevation is set on the LDG ELEV selector? (FM: 8.20.60.4)
500 feet
When the landing elevation is selected with the LDG ELEV selector, the cabin altitude is (FM:8.20.50.1)
Still controlled automatically through the outflow valve.
How is the pressurization system controlled manually? (FM: 8.20.50.2)
Selecting MODE SEL switch to MAN and using the MAN V/S CTL switch to control the outflow valve.
