If a display fails, the appropriate interface between that display and the associated GIA is
cut off. Thus, the GIA can no longer communicate with the remaining display. The NAV
and COM functions provided to the failed display by the GIA are flagged as invalid on the
remaining display. The system reverts to backup paths for the AHRS, ADC, Engine/
Airframe Unit, and Transponder, as required. The change to backup paths is completely
automated for all LRUs and no pilot action is required.
If the system fails to detect a display problem, Reversionary mode can be manually
activated by pressing the red DISPLAY BACKUP button on the audio panel. Pressing
this button again deactivates Reversionary Mode.
2.3.5 Configuration Mode
Configuration mode enables configuring, checking, and calibrating the various G1000
NXi subsystems. Troubleshooting and diagnostics information can also be derived from
the configuration pages when the system is in this mode.
To enter configuration mode:
1. Press and hold the ENT key on the PFD while applying power.
2. Release the ENT key after INITIALIZING SYSTEM is displayed in the upper left
corner of the PFD.
3. Supply electrical power to the MFD and PFD2 in the same manner. It is best to
have all displays in the same mode.
4. The system is now in configuration mode. The System Upload page is displayed
(see Figure 2-12 and Figure 2-13).
