See the Aircraft Flight Manual (AFM) for specific procedures concerning avionics power application 

and emergency power supply operation.

Refer to Appendix A for system-specific annunciations and alerts.

The G1000 System is integrated with the aircraft electrical system and receives power directly from electrical 

busses.  The 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.

During system initialization, test annunciations are displayed, as shown in Figure 1-7.  All system annunciations 

should disappear typically within the first minute of power-up.  Upon power-up, key annunciator lights also 
become momentarily illuminated on the Audio Panel.

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 the first minute of power-up.  The AHRS can align itself 
both while taxiing and during level flight.

When the MFD powers up, the power-up screen (Figure 1-8) displays the following information:

• System version
• Copyright
• Land database name and version
• Safe Taxi database information
• Terrain database name and version

• Obstacle database name and version
• Navigation database name, version, and effective dates
• Airport Directory name, version and effective dates
• FliteCharts/ChartView database information

Current database information includes database type, cycle number, or valid operating dates.  Review the listed 

information for currency (to ensure that no databases have expired).

Pressing the ENT Key (or right-most softkey) acknowledges this information, and the Navigation Map Page is 

displayed upon pressing the key a second time.  When the system has acquired a sufficient number of satellites to 
determine a position, the aircraft’s current position is shown on the Navigation Map Page.
