SYSTEM OVERVIEW
1.8 DISPLAY BACKLIGHTING
The G1000 display and control backlighting can be adjusted either automatically or manually. Backlighting
intensity ranges from 0.22% to 100% on the PFDs and 0.80% to 100.00% on the MFD.
AUTOMATIC ADJUSTMENT
The existing instrument panel dimmer bus normally controls the PFD and MFD bezels, MFD Control Unit,
AFCS Control Unit and audio panel key annunciator lighting. When the dimmer bus is not used by the G1000
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:
In normal mode, backlighting can only be adjusted from PFD1 or PFD2. 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 on-side PFD key backlighting setting.
To 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 ‘PFD1 DSPL’.
