APPENDIX A
G1000 SYSTEM MESSAGE ADVISORIES
This section provides information regarding G1000 message advisories that may be displayed by the
NOTE:
system. Knowledge of the aircraft, systems, flight conditions, and other existing operational priorities must
be considered when responding to a message.
This section describes various G1000 System message advisories. Certain messages are issued due to an LRU
or LRU function failure. Such messages are normally accompanied by a corresponding red 'X' annunciation as
shown previously in the G1000 System Annunciations section.

Comments
Abort approach due to loss of GPS navigation.
GDC1 is reporting that the altitude error correction is unavailable.
GDC1 is reporting that the airspeed error correction is unavailable.
The #1 AHRS calibration version error. The system should be serviced.
The #1 AHRS is using the backup GPS path. Primary GPS path has failed. The G1000
system should be serviced when possible.
The #1 AHRS is not receiving any or any useful GPS information. Check AFMS
limitations. The G1000 system should be serviced.
The #1 AHRS is not receiving backup GPS information. The G1000 system should be
serviced.
The #1 AHRS is operating exclusively in no-GPS mode. The G1000 system should be
serviced.
The #1 AHRS earth magnetic field model is out of date. Update magnetic field model
when practical.
The #1 AHRS is not receiving true airspeed from the air data computer. The AHRS
relies on GPS information to augment the lack of airspeed. The G1000 system should
be serviced.
Use LNAV minima when approach is downgraded.
Special use airspace is ahead of aircraft. The aircraft will penetrate the airspace within
10 minutes.
Special use airspace is within 2 nm of the aircraft position.
Special use airspace is near and ahead of the aircraft position.
when required.
The GDC 74B has incorrect software installed. The G1000 system should be serviced.
