System Power-Up - Garmin G1000 Pilot's Manual

1.5 SYSTEM POWER-UP

See the Aircraft Flight Manual (AFM) for specific procedures concerning avionics power application
NOTE:
and emergency power supply operation.
Refer to Appendix A for system-specific annunciations and alerts.
NOTE:
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 1-6. 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 splash screen (Figure 1-7) displays the following information:
• System version
• Copyright
• Land database name and version
• Obstacle database name and version
• Terrain database name and version
Current database information includes 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 (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.
