Flight Instruments EICAS Nav/Com/ XPDR/Audio AFCS GPS Nav Abnormal Operation ABNORMAL OPERATION 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.
