Pressurization Flashcards
Which of the following DOES NOT provide input to the pressurization controllers?
FADECs
The input provided by the Flight Management and Guidance Computers (FMGCs) enable the pressurization controllers to:
Know the planned cruise altitude and plan the cabin climb profile accordingly.
The pressurization controllers use the elevation of your destination airport to plan the descent profile. In normal operations, this information is provided:
By the FMS database once you enter the destination airport into the MCDU.
With the pressurization in manual mode, the outflow valve is now controlled by:
The MAN V/S control switch.
On landing, cabin altitude will be:
Slightly lower than field pressure altitude.
Pressurization Abort Mode:
Is activated if aircraft must return to the departure airport after takeoff.
Which control would you use to manually switch from the automatic pressurization control to manual control?
Mode SEL to MAN.
With the pressurization in manual mode, the outflow valve is now controlled by:
The MAN V/S control switch.
With MODE SEL in MAN, moving the MAN V/S:
UP opens the outflow valve and DN closes it.
The cabin pressurization controllers receive information from the FMGCs for landing elevation. By reviewing the Cabin Pressurization page, you can verify this by:
LDG ELEV AUTO 650 FT
On this CRUISE page, why is the cabin vertical speed indicator in an analog format?
The MODE SEL pb has been selected to MAN, and the pressurization system is being operated in the manual mode.
If both controllers fail, operation is automatically transferred to manual control.
False
How can you manually set the field elevation?
Pulling LDG ELEV selector out and dialing it against outer scale.
The ditching pushbutton is used to:
Close all fuselage openings below the floatation line.
On landing, cabin altitude will be:
Slightly lower than field pressure altitude.
In Ground Mode, the outflow valve will:
Gradually open during landing rollout.
Pressurization Abort Mode:
Is activated if aircraft must return to the departure airport after takeoff.
