PRESSURIZATION MENU Normal operation 1/18
PRESSURIZATION MENU
Normal operation 2/18
We will now look at the normal operation of the
pressurization system.
As part of your Pre-flight walk around you should visually
check the outflow valve for damage and obstruction.
PRESSURIZATION MENU
Normal operation 3/18
As part of your pre flight cockpit scan, verify on the Cabin
Pressure Panel that the Mode selector switch is in the
AUTO position, lights out.
PRESSURIZATION MENU
Normal operation 4/18
Confirm that the Landing Elevation Selector is set to
AUTOMATIC. Landing elevation is then provided by the
FMGS based upon elevation of the destination airport.
PRESSURIZATION MENU
Normal operation 5/18
Also confirm that the DITCHING sw is in the OFF position,
lights out.
PRESSURIZATION MENU
Normal operation 6/18
On the ECAM CAB PRESS Page confirm that the Landing
Elevation Indication is AUTO.
Once the destination airport has been entered into the
FMGS the destination landing elevation is displayed.
PRESSURIZATION MENU
Normal operation 7/18
Notice that there are no amber indications.
PRESSURIZATION MENU
Normal operation 8/18
So that you can get a better understanding of how the
pressurization system works we will go through a normal
flight profile paying particular attention to the ECAM
indications.
PRESSURIZATION MENU
Normal operation 9/18
When the aircraft is on the ground before the flight, the
outflow valve is fully open and there is no pressure
differential.
This can be seen on ECAM CAB PRESS page.
PRESSURIZATION MENU Normal operation 10/18
PRESSURIZATION MENU
Normal operation 11/18
Observe that:
• the outflow valve is fully open,
• the differential pressure is zero,
• there is no vertical speed,
• the cabin altitude is indicating the field elevation of the
departure airfield.
PRESSURIZATION MENU
Normal operation 12/18
During the Take off roll the system controller signals the
outflow valve to close slightly in order to pre-pressurize
the aircraft.
This is to avoid a pressure surge at rotation.
Take off
PRESSURIZATION MENU
Normal operation 13/18
Climb Phase
At Lift Off the controller initiates the climb phase and
cabin altitude varies according to a fixed law taking into
account the actual rate of climb of the aircraft. The
outflow valve will move as required to achieve this.
PRESSURIZATION MENU
Normal operation 14/18
Cruise at 35000ft
Once established in cruise the cabin altitude and
differential pressure will remain steady. The outflow valve
will move as required to maintain the cabin altitude. In
the example shown the aircraft is in cruise at 35000 feet.
Notice the values of differential pressure and cabin
Altitude.
PRESSURIZATION MENU
Normal operation 15/18
While in flight we can monitor all the major pressurization
indications on the ECAM CRUISE Page.
PRESSURIZATION MENU
Normal operation 16/18
Descent
During the descent phase the pressure rate is optimized
so that the cabin reaches landing field pressure just prior
to landing.
Note: for passenger comfort the automatic function will limit the
rate of cabin descent to a maximum of approximately 750 feet
per minute.
PRESSURIZATION MENU
Normal operation 17/18
Landing
At touchdown the cabin altitude should be at the airfield
elevation, and there should be no differential pressure.
To ensure this, just after landing, the outflow valve is
fully opened by the system controller.
PRESSURIZATION MENU Normal operation 18/18
Once the outflow valve is fully opened there is an
automatic change over of the system controllers in
preparation for the next flight. This happens so that both
systems are used equally.
