OVERHEAD PANEL
Applicable to: ALL
(1) LDG ELEV selector
AUTO : The pressurization system uses the FMGS data to construct an optimized
pressure schedule. To exit the AUTO position, pull out and turn the
selector.
Other positions : The pressurization schedule does not use the landing elevation from the
FMGS, but instead uses the landing elevation selected with this knob
(from -2 000 to 14 000 ft) as its reference.
Note: The LDG ELEV selector scale is only given as an indication ; refer to the ECAM
information for accurate adjustment.
(2) MODE SEL pushbutton
AUTO : Automatic mode is operating. One of the two systems controls the outflow valves.
Note: If the pilot suspects that the operating pressurization system is not
performing properly, he can attempt to select the other system by
switching the MODE SEL pushbutton to MAN, for at least 3 s, then
returning it to AUTO.
MAN : This legend appears in white, and FAULT does not come on. The flight crew then
uses the MAN V/S CTL switch to control the system.
FAULT lt : This legend appears in amber and the ECAM caution only comes on when both
automatic systems are faulty.
Note: The pilot may notice variations (up to ± 1 000 ft) in the CAB ALT
indication on the ECAM PRESS page, when the system switches from
the cabin pressure control AUTO mode to MAN mode, due to reduced
resolution of the backup pressure sensor.

(3) V/S CTL switch
The switch is springloaded to neutral and controls the outflow valve position selected through
the VALVE SEL. It controls the MAN motor, when the MODE SEL pushbutton is in the MAN
position.
UP : The valve(s) move(s) towards the open position.
DN : The valve(s) move(s) towards the closed position.
(4) VALVE SEL selector
AFT : The aft outflow valve can be manually controlled. The forward outflow valve remains under
automatic control.
BOTH :
(guarded position)
Both outflow valves can be manually controlled.
FWD : The forward outflow valve can be manually controlled. The aft outflow valve remains under
automatic control.
(5) DITCHING pushbutton
Normal: The system functions normally.
ON : The outflow valves, emergency ram air inlet, avionics ventilation overboard valve,
cargo compartment isolation valves, and pack flow control valves close. The cargo
recirculation fans stop automatically.
The ON light appears in white.
Note: The outflow valve(s) will not close automatically, if it (they) is (are) under
manual control.
CAUTION On ground, if the ditching pushbutton is set to ON, with the low
pressure ground cart connected and all doors closed, a differential
pressure will build up.

ECAM CAB PRESS PAGE
Applicable to:
(1) LDG ELEV AUTO / MAN
LDG ELEV AUTO : appears in green when the LDG ELEV selector is in AUTO.
Becomes amber if the landing elevation is not transmitted by the
FMGS.
LDG ELEV MAN : appears in green when the LDG ELEV selector is not in AUTO.
Neither appear when the MODE SEL pushbutton switch is in MAN and the VALVE SEL
selector is in BOTH, or when the LDG ELEV selector is faulty.
(2) Landing Elevation
Landing elevation selected either automatically by the FMGS or manually by the pilot appears
in green. (But not when the MODE SEL pushbutton is in MAN position and the VALVE SEL is
in BOTH position).
(3) V/S FT/MIN (cabin vertical speed)
The analog and digital presentation appear in green when V/S is in the normal range.
The digital indication pulses, when the V/S is more than 1 800 ft/min in either climb or descent.
(4) ▵P PSI (Cabin differential pressure)
The scale is displayed in white. The analog and digital presentations appear in green when ▵P
is the normal range.
They appear in amber when ▵P ≤ -0.26 PSI or ≥ 8.85 PSI.
The digital presentation pulses if ▵P > 1.5 PSI (resets at 1 PSI) during flight phase 7.
