18.2 SD Card Use and Databases
The GTN 6XX System uses Secure Digital (SD) cards to load and store various
types of data. For basic flight operations, SD cards are required for database
storage as well as database updates.
18.2.1 Jeppesen Databases
The navigation database is updated on a 28-day cycle. Navigation database
updates are provided by Garmin and may be downloaded from the Garmin web
site “fly.garmin.com” onto a Garmin provided Supplemental Data card. Contact
Garmin at fly.garmin.com for navigation database updates and update kits. The
Navigation database is stored internally and the data card is only used to transfer
the database into the unit.
NOTE:
Garmin requests that the flight crew report any observed
discrepancies related to database information. These discrepancies could
come in the form of an incorrect procedure, incorrectly identified terrain,
obstacles and fixes, or any other displayed item used for navigation or
communication in the air or on the ground. Go to “FlyGarmin.com” and at
the bottom of the page select “Aviation Data Error Report.”
Updating the Jeppesen navigation database
1. With the GTN 6XX System OFF, insert the SD card containing the
navigation database update into the card slot of the GTN 6XX
to be updated (label of SD card should face to the right).
2. Turn the GTN 6XX System ON.
3. Verify the correct update cycle is loaded during power-up.
