NOTE
●
A list of abbreviations used in this chapter is given in figure 7.10.2.
●
The airplane is equipped with a Global Air System (GAS), which ensures air
conditioning and pressurization control - see figure 7.10.2.
-
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 zones 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 set in the airplane.
The GASC elaborates the proper 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 arm rest of the L.H. side passenger's seat.
The pilot monitors the system through gauges and CAS messages appearing on the
MFD. These indications are independent of the GASC controls and internal sensors.
