SYSTEM OVERVIEW

1.6 DISPLAY BACKLIGHTING

The G1000 PFD and MFD displays use photocell tech-

nology to automatically adjust for ambient lighting con

ditions. Photocell calibration curves are pre-conﬁgured

to optimize display appearance through a broad range of

cockpit lighting conditions. PFD, MFD, and GMA 1347

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. PFD, MFD, and GMA 1347

bezel/key brightness can also be adjusted manually as

well. GMA 1347 bezel/key brightness is directly tied to

the MFD bezel/key adjustment.

NOTE: Refer to the Primary Flight Display section

for instructions on how to manually adjust the

display backlighting.

1.7 SYSTEM OPERATION

NORMAL MODE

The PFD and MFD are connected together on a single

Ethernet bus, allowing for high-speed communication be

tween 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, enabling true system integration.

In normal operating mode, the PFD displays graphical

ﬂight instrumentation in lieu of traditional gyro instru

ments. 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 selec

tion, 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.
