NOTE

A list of abbreviations used in this chapter is given in figure 7.9.2.
●
The airplane is equipped with a Global Air System (GAS), which ensures air
conditioning and pressurization control - see figure 7.9.2.
-
Air conditioning corresponds to the cockpit / cabin air temperature
management.
-
Pressurization corresponds to the cabin altitude / rate of change
management.
The GAS is composed of 3 sub-systems :
-
engine bleed air system,
-
cabin pressurization control system,
-
dual-zone Environmental Control System, which includes heating and cooling
functions.
These sub-systems are managed by a single digital controller, the GASC, which
receives information from :
-
the sensors within the sub-systems,
-
the human interfaces integrated in the airplane.
The GASC sends commands to the sub-systems actuators and indication or warning
elements.
GAS controls are located on :
-
the A/C panel on the left side of the left control wheel,
-
the PRESSURIZATION panel on the right side of the left control wheel,
-
a control panel above the armrest of the left-side passenger seat.
The pilot monitors the system through information and CAS messages displayed on
the MFD. These indications are independent of the GASC controls and internal
sensors.
