1.4 SYSTEM OPERATION
The displays are connected together via a single Ethernet bus, thus allowing for high-speed communication.
As shown in Figure 1-1, each IAU is connected to the on-side display. This section discusses the normal and
reversionary modes of operation as well as the various AHRS modes of the system.
DISPLAY OPERATION
NOTE:
In normal operating mode, backlighting can only be adjusted from the PFD, or from any display
operating in reversionary mode.
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 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
(EIS; see the EIS Section). The PFD offers control for COM frequency selection and the MFD offers control
for NAV frequency selection. The PFD/MFD Control Unit offers control for both COM and NAV frequency
selection.
