3.3 Reversionary Mode
Should a display communication or hardware failure occur, the G1000 system automatically enters the
reversionary mode. The system reversionary mode forces the remaining display into showing all
information related to safe flight.
A manual reversionary mode also allows the operator to force the system into reversionary mode in
situations where the system does not automatically enter reversionary mode. A large red button on the
GMA 1347 audio panel activates the manual reversionary mode.
Figure 3-5. MFD Failure Mode
Should the PFD display fail, the MFD automatically enters reversionary mode. In this mode, flight-
critical information from the AHRS/Air Data system is displayed on the MFD along with essential engine
instrumentation.
