1.6 DISPLAY BACKLIGHTING

NOTE: Refer to the Primary Flight Display section
for instructions on manually adjusting the
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. PFD, MFD, and Audio Panel
bezel/key lighting are normally controlled directly by the
existing instrument panel dimmer bus.
If desired, PFD and MFD display backlighting and
PFD, MFD, and Audio Panel bezel/key brightness can also
be adjusted manually. Audio Panel bezel/key brightness is
directly tied to MFD bezel/key adjustment.

between the two units. 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.
graphical flight instrumentation in lieu of traditional gyro
instruments. Attitude, heading, airspeed, altitude, and
vertical speed are all shown on one display (refer to the
PFD section for more information). The MFD shows a
full-color moving map with navigation information (refer
to the MFD section for a complete discussion of MFD
operation). Both displays offer control of COM and NAV
frequency selection, as well as heading, course/baro, and
altitude select functions. On the left of the MFD display,
the Engine Indication System (EIS) cluster shows engine
and airframe instrumentation (see the EIS section). The
following figure shows an example of normal G1000
