(6) Active system indication (SYS 1 or SYS 2 or MAN)
SYS 1 or SYS 2 appears in green when active and in amber when faulty. When either system
is inactive, its title does not appear.
MAN appears in green when the MODE SEL switch is in MAN.
(7) Safety valve position
SAFETY appears in white and the diagram in green when both safety valves are fully closed.
SAFETY and the diagram appear in amber when either valve is not closed.
Note: The safety valve opens when the cabin differential pressure is between 8.2 and
78ORHSgdqmfdhrctdsnsgdqdctbdcbbtqbxneΔOldrtqdldmsrhmLM
mode), combined with the decrease in cabin differential pressure that occurs
immediately after the safety valves open.
(8) Outflow valve position
The diagram is green when the valve is operating normally.
The diagram becomes amber when the valve opens more than 95 % during flight.

(1) LDG ELEV AUTO/MAN
LDG ELEV AUTO : appears in green when the LDG ELEV selector is in AUTO.
LDG ELEV AUTO : appears in green when the LDG ELEV selector is not in AUTO.
Neither appears when the indications from SDAC are not valid.

(2) Landing elevation
The landing elevation selected either automatically by the FMGS or manually by the pilot
appears in green (but not when the MODE SEL pushbutton switch is in MAN).
(3) V/S FT/MIN (cabin vertical speed)
The analog and digital presentations appear in green when V/S is in the normal range.
The digital presentation pulses when V/S > 1 750 ft/min (resets at 1 650 ft/min).
(4) ΔP PSI (cabin differential pressure)
The analog and digital presentations appear in green when ▵P is in the normal range.
They appear in amber when ΔP ≤ –0.4 PSI or ≥ 8.5 PSI.
The digital presentation pulses if Δp > 1.5 PSI (resets at 1 PSI) during flight phase 7. (Refer to
DSC-21-20-50 WARNINGS AND CAUTIONS).
(5) CAB ALT FT (cabin altitude)
The analog and digital presentations appear in green, in normal range.
They appear in red if the cabin altitude goes above 9 550 ft.
The digital presentation pulses if the cabin altitude is at or above 8 800 ft (resets at 8 600 ft).
(6) Active system indication (SYS 1 or SYS 2 or MAN)
SYS 1 or SYS 2 appears in green when active and in amber when faulty. When either system
is inactive, its title does not appear.
MAN appears in green when the MODE SEL switch is in MAN.
(7) Safety valve position
SAFETY appears in white and the diagram in green when both safety valves are fully closed.
SAFETY and the diagram appear in amber when either valve is not closed.
Note: The safety valve opens when the cabin differential pressure is between 8.2 and
8.9 PSI. The range is due to the reduced accuracy of ΔOldrtqdldmsrhmLM
mode), combined with the decrease in cabin differential pressure that occurs
immediately after the safety valves open.
(8) Outflow valve position
The diagram is green when the valve is operating normally.
The diagram becomes amber when the valve opens more than 95 % during flight.

Identifical to the CAB PRESS page.
(2) CAB V/S FT/MIN (cabin vertical speed)
Green, in normal range.
Amber, when out of normal range : V/S ≥ 2 000 ft/min
Pulses, when the V/S > 1 800 ft/min (resets at 1 600 ft/min).
(3) CAB ALT FT (cabin altitude)
Green, in normal range.
Red, for excessive cabin altitude : ≥ 9 550 ft.
Pulses for cabin altitude at, or above, 8 800 ft (resets at 8 600 ft).
(4) ▵P indication
It is normally green.
It becomes amber, when out of normal range ▵p ≤ -0.4 PSI or ≥ 8.5 PSI.
