The displays are connected via a single Ethernet bus, thus allowing for high-speed communication.  As shown 

in Figure 1-1.  The GIA 63W #1 is connected to PFD1 and GIA 63W #2 is connected to the HSDB switch.  This 
section discusses the normal and reversionary modes of operation as well as the various AHRS modes of the 
system.

In the event of display failure, the display modes are as follows:

• PFD1 failure – MFD enters reversionary mode; PFD2 remains in normal mode.

• MFD failure – PFD1 and PFD2 enter reversionary mode.

• PFD2 failure – PFD1 and the MFD remain in normal mode.

In normal mode, the PFD presents graphical flight instrumentation (attitude, heading, airspeed, altitude 

and vertical speed), thereby replacing the traditional flight instrument cluster.  The PFD also offers control for 
COM and NAV frequency selection.

In normal mode, the right portion of the MFD displays a full-color moving map with navigation information, 

while the left portion of the MFD is dedicated to engine, fuel, electrical, cabin pressurization, oxygen, landing 
gear, and trim/flaps indication.
