SYSTEM OVERVIEW
1.6 SYSTEM OPERATION
NOTE:
In normal operating mode, backlighting can only be adjusted from the PFD. In reversionary mode, it
can be adjusted from the remaining display.
The displays are connected together via a single Ethernet bus for high-speed communication.
Each IAU is
connected to a single display, as shown in Figure 1-1. This allows the units to share information, enabling true system
integration.
. This section discusses normal and reversionary G1000H display operation, as well as the various
AHRS modes and G1000H System Annunciations.
NORMAL DISPLAY OPERATION
In normal operating mode, the PFD presents graphical flight instrumentation (attitude, heading, airspeed,
altitude, vertical speed), replacing the traditional flight instrument cluster (see the Flight Instruments Section
for more information). The Power Situation Indicator and CAS messages are also displayed on the PFD.
The MFD normally displays a full-color moving map with navigation information (see the Flight Management
Section), while the left portion of the MFD is dedicated to the Engine Indication System (EICAS; see the EICAS
Section).
Both displays offer control for COM and NAV frequency selection.
