Appendix F

REVERSIONARY MODE (FULL-SCREEN)

In the event of a display failure, the G3X System automatically switches to
reversionary (backup) mode. In reversionary mode, the information is presented on
the remaining display in the split-screen configuration.
If a display failure occurs with the GDU 375, the WX and XM Pages will no longer
be available since the XM receiver resides in the GDU 375.

AFCS REVERSIONARY MODE

In a two display system, in the event of a PFD failure, the MFD goes into reversionary
mode, and the autopilot is disengaged. If the MFD fails, the PFD goes into reversionary
mode and the autopilot continues to function.
In a GMC 305 installation, in the event of display failure(s), basic autopilot
functionality remains as long as a ADAHRS unit is still available. The FD is no longer
available, but LVL, AP, ALT, and YD are available.

FAILURE OF THE EXTERNAL GPS NAVIGATION SOURCE

If the external GPS navigation source fails, the system reverts to the internal GPS
navigation source and 'REV' is shown in yellow in the upper left corner of the Data Bar
as well as the lower left quadrant of the HSI.
