SYSTEM OVERVIEW
AIR DATA INPUT FAILURE
A failure of the air data input has no effect on AHRS output while AHRS is operating in normal mode. A
failure of the air data input while the AHRS is operating in reversionary No-GPS mode results in invalid
attitude and heading information on the PFD (as indicated by red “X” flags).
MAGNETOMETER FAILURE
If the magnetometer input fails, the AHRS transitions to one of the reversionary No-Magnetometer modes
and continues to output valid attitude information. However, if the aircraft is airborne, the heading output
on the PFD does become invalid (as indicated by a red “X”).
G1000H SYSTEM ANNUNCIATIONS
NOTE:
For a detailed description of all annunciations and alerts, refer to Appendix A. Refer to the
Rotorcraft Flight Manual Supplement (RFMS) for additional information regarding pilot responses to these
annunciations.
When an LRU or an LRU function fails, a large red “X” is typically displayed on windows associated with the
failed data (Figure 1-11 displays all possible flags and responsible LRUs). Upon G1000H power-up, certain
windows remain invalid as equipment begins to initialize. If any window remains flagged, the G1000H system
should be serviced by a Garmin-authorized repair facility.
