Post Installation Configuration and Checkout
NOTE
The GMA 1347D does not provide valid outputs until the aircraft post installation
configuration procedures are completed.
The GMA 1347D must be installed with a Garmin G1000 system and have FAA approved configuration
data. Configuration data is loaded to the GMA 1347D from an aircraft-specific G1000 SW Loader Card.
The G1000 PFD serves as the graphical user interface to be used by the installer that is configuring the
system. For basic configuration information, refer to the G1000 Line Maintenance and Configuration
Manual, Garmin part number 190-00303-04. For actual aircraft installation/checkout, use only aircraft
manufacturer approved checkout procedures.
