SYSTEM OVERVIEW

1.6 DISPLAY BACKLIGHTING

The G1000 PFD and MFD displays use photocell

technology to automatically adjust for ambient lighting

conditions. Photocell calibration curves are pre-conﬁgured

to optimize display appearance through a broad range

of cockpit lighting conditions. The PFD, MFD, and

Audio Panel bezel/key lighting is normally controlled

directly by the existing instrument panel dimmer bus.

If desired, the PFD and MFD display backlighting may

be adjusted manually. The PFD, MFD and Audio Panel

bezel/key brightness can also be adjusted manually. The

Audio Panel bezel/key brightness is directly tied to the

MFD bezel/key adjustment.

NOTE: Please refer to the Primary Flight Display

Pilot’s Guide for instructions on adjusting

backlighting manually.

1.7 SYSTEM OPERATION

NORMAL MODE

The PFD and MFD are connected together on a single

Ethernet bus, allowing for high-speed communication

between the two units. Each GIA 63 is connected to a

single display, as shown in Figure 1-1. This allows the

units to share information, thus enabling true system

integration.

In normal operating mode, the PFD displays graphical

ﬂight instrumentation in lieu of the traditional gyro

instruments. Attitude, heading, airspeed, altitude

and vertical speed are all shown on one display. The

MFD shows a full-color moving map with navigation

information. Both displays offer control for COM and NAV

frequency selection, as well as for the heading, course/baro

and altitude reference functions. On the left of the MFD

display, the Engine Indication System (EIS) cluster shows

engine and airframe instrumentation. Figure 1-6 gives an

example of the G1000 system in normal mode.
