REVERSIONARY DISPLAY OPERATION

The G1000 System alerts the pilot when backup paths are utilized by the LRUs. Refer to Appendix A
NOTE:
for further information regarding system-specific alerts.
In the event of a display failure, the G1000 System automatically switches to reversionary (backup) mode. In
reversionary mode, all important flight information is presented on the remaining display in the same format
as in normal operating mode.
If a display fails, the appropriate IAU-display Ethernet interface is cut off. Thus, the IAU can no longer
communicate with the remaining display, and the NAV and COM functions provided to the failed display by the
IAU 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 may be manually activated by pressing
the Audio Panel' s red DISPLAY BACKUP button (refer to the Audio Panel and CNS Section for further details).
Pressing this button again deactivates reversionary mode.
