ABNORMAL OPERATION
REVERSIONARY MODE
Should a system detected failure occur in either display, the G1000 automatically
enters reversionary mode. In reversionary mode, critical flight instrumentation is
combined with engine instrumentation on the remaining display. Minimal navigation
capability is available on the reversionary mode display.
Reversionary display mode can be manually activated by pressing the
DISPLAY
BACKUP Button on the audio panel.
NOTE: The Cessna Caravan Pilot’s Operating Handbook (POH) always takes
precedence over the information found in this section.
ABNORMAL COM OPERATION
When a COM tuning failure is detected by the system, the emergency frequency
(121.500 MHz) is automatically loaded into the active frequency field of the COM
radio for which the tuning failure was detected. In the event of a failure of both PFDs,
the emergency frequency (121.500 MHz) automatically becomes the active frequency
on both COM radios.
HAZARD DISPLAYS WITH LOSS OF GPS POSITION
If GPS position is lost, or becomes invalid, selected hazards being displayed on the
Navigation Map Page are removed until GPS position is again established.
