SYSTEM OVERVIEW
1.5 SYSTEM POWER-UP
NOTE: Refer to the Appendices for AHRS initialization bank angle limitations.
NOTE: See the Appendices for additional information regarding system-specific annunciations and alerts.
NOTE: See the Airplane Flight Manual (AFM) for specific procedures concerning avionics power application
and emergency power supply operation.
The G1000 system is integrated with the aircraft electrical system and receives power directly from electrical
busses. The G1000 PFDs, 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.
During system initialization, test annunciations are displayed, as shown in Figure 1-7. All system annunciations
should disappear typically within one (1) minute of power-up. Upon power-up, key annunciator lights also
become momentarily illuminated on the audio panels, the control units and the display bezels.
On the PFD, the AHRS begins to initialize and displays ‘AHRS ALIGN: Keep Wings Level’. The AHRS should
display valid attitude and heading fields typically within one (1) minute of power-up. The AHRS can align itself
both while taxiing and during level flight.
When the MFD powers up (Figure 1-8), the MFD Power-up Page displays the following information:
• System version
• Copyright
• Land database name and version
• Obstacle database name and version
• Terrain database name and version
• Aviation database name, version and effective dates
• Chartveiw database information
• Safe Taxi database information
Current database information includes the valid operating dates, cycle number and database type. When this
information has been reviewed for currency (to ensure that no databases have expired), the pilot is prompted
to continue. Pressing the
ENT
Key
acknowledges this information and displays the Auxiliary (AUX) Weight
Planning Page.
