SYSTEM OVERVIEW
1.8 DISPLAY BACKLIGHTING
The G1000H display and control backlighting can be adjusted either automatically or manually.
AUTOMATIC ADJUSTMENT
The existing instrument panel dimmer bus normally controls the PFD and MFD backlighting as well as the
PFD and MFD bezels and audio panel key annunciator lighting. When the dimmer bus is not used by the
G1000H system, photocell technology automatically controls backlighting adjustments. Photocell calibration
curves are pre-configured to optimize display appearance through a broad range of cockpit lighting conditions.
MANUAL ADJUSTMENT
NOTE:
The avionics dimming knob may also be used to adjust backlighting. Refer to the POH for details.
NOTE:
In normal mode, backlighting can only be adjusted from the PFD. In reversionary mode, it can also
be adjusted from the MFD.
NOTE:
No other window can be displayed on the PFD while the PFD Setup Menu Window is displayed.
Backlighting may also be adjusted manually for all of the displays and the associated bezels.
The audio panel
key backlighting is directly tied to the PFD key backlighting setting.
Adjust display backlighting manually:
1)
Press the
MENU
Key on the PFD to display the PFD Setup Menu Window. ‘AUTO’ becomes highlighted to the
right of ‘PFD DSPL’.
