Applying Power To The System - Garmin G1000 Pilot's Manual

1.4 APPLYING POWER TO THE SYSTEM

NOTE: See the current pertinent flight manual for specific procedures concerning avionics power application
and emergency power supply operation.
The system is integrated with the aircraft electrical system and receives power directly from electrical busses.
The 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. All system annunciations should disappear
typically within the first minute of applying power. During this time, key annunciator lights also become
momentarily illuminated on the Audio Panel 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 the first minute of applying power. The AHRS can align
itself both while taxiing in a straight line and during level flight.
When the MFD powers on, the initial screen displays the following information:
• System version
• Copyright
• Land database name and version
• SafeTaxi database name and expiration date
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 MAP – 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 MAP – NAVIGATION MAP Page.
