Abnormal Operation; Reversionary Mode; Abnormal Com Operation; Hazard Displays With Loss Of Gps Position - Garmin Beil 407GX Cockpit Reference Manual

REVERSIONARY MODE

Should a system detected failure occur in either display, the G1000H automatically
enters reversionary mode. In reversionary mode, critical flight instrumentation is
combined with engine instrumentation on the remaining display.
Reversionary display mode can be manually activated by pressing the DU BACKUP
Button on the instrument panel.
NOTE: The Bell 407GX Rotorcraft Flight Manual (RFM) 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.
