213, Pressurization Flashcards
Which of the following DOES NOT provide input to the pressurization controllers?
LGCIUs
Thrust Levers
ADIRUs
FADECs
FADECs
The input provided by the Flight Management and Guidance Computers (FMGCs) enable the pressurization controllers to:
Know when you are commencing takeoff.
Know when you are on the ground.
Know the planned cruise altitude and plan the cabin climb profile accordingly.
Know your current rate of climb.
Know the planned cruise altitude and plan the cabin climb profile accordingly.
The following areas are not pressurized:
Air conditioning compartment and tail.
Radome, landing gear bays, air conditioning compartment and tail.
Radome and landing gear bays.
Cargo compartment.
Radome, landing gear bays, air conditioning compartment and tail.
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.
From the elevation selected using the LDG ELEV selector on the overhead CABIN PRESS panel.
Only after the aircraft rate of descent is greater that 200 ft/min for 30 seconds.
By the FMS database once you begin the descent.
By the FMS database once you enter the destination airport into the MCDU.
The two pneumatic pressurization safety valves:
Open automatically when it becomes necessary to relieve excess positive cabin pressure differentials only.
Open automatically when it becomes necessary to relieve excess negative cabin pressure differentials only.
Open automatically when it becomes necessary to relieve excess positive or negative cabin pressure differentials.
Are opened by using the DITCHING pb.
Open automatically when it becomes necessary to relieve excess positive or negative cabin pressure differentials.
After landing, the active and standby pressurization controllers:
Automatic transfer occurs after 70 seconds.
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 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.
