REVERSIONARY DISPLAY OPERATION
NOTE:
The system alerts the pilot when backup paths are utilized by the LRUs. Refer to the Appendices 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 from the PFD is presented on the operating display in the
same format as in normal operating mode, with the addition of the EIS. EIS operation while in Reversionary
Mode is discussed in the EIS Section. As when the PFD is operating normally, windows for flight planning,
nearest airports, and procedures are available. The Inset Map is moved to the right side of the display.
If a display fails, the appropriate IAU-display Ethernet interface is cut off. Thus, the IAU can no longer
communicate with the operating display (refer to Figure 1-1), and the NAV and COM functions provided to
the failed display by the IAU are flagged as invalid on the operating 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 & CNS Section for further details).
Pressing this button again deactivates Reversionary Mode.
