SYSTEM OVERVIEW
2.5 SYSTEM POWER-UP
The G1000 system is integrated with the aircraft elec-
trical system and receives power directly from electrical
busses. The Garmin G1000 PFD/MFD and supporting
sub-systems include both power-on and continuous built-
in test features that exercise the processor, RAM, ROM,
external inputs and outputs to provide safe operation.
While the system begins to initialize, test annunciations
are displayed to the pilot at power-up, as shown in the
figure below. All system annunciations should be cleared
within one (1) minute of power-up. The GMA 1347 also
annunciates all bezel lights briefly upon power-up.
NOTE: Refer to the Beechcraft A36/G36 Pilot’s
Operating Handbook (POH) for specific proce-
dures concerning avionics power application and
emergency power supply operation.
On the PFD, the AHRS system displays the ‘AHRS
ALIGN: Keep Wings Level’ message and begins to initial-
ize. The AHRS should display valid attitude and heading
fields within one (1) minute of power-up. The AHRS can
align itself both while taxiing and during level flight.
NOTE: Refer to the Pilot’s Guide Appendices for
AHRS initialization bank angle limitations.
NOTE: See the Annunciations and Alerts Pilot’s
Guide for additional information regarding
system annunciations and alerts.
