Foreword System Sec 1 PFD Sec 2 MFD Sec 3 Features Avoidance Hazard Sec 4 Additional Garmin Databases NOTE: The data contained in the terrain and obstacle databases comes from government agencies. Garmin accurately processes and cross-validates the data, but cannot guarantee the accuracy and completeness of the data. The following GDU 620 databases are stored on Supplemental Data Cards provided by Garmin: • Terrain - The terrain database contains terrain mapping data. It is updated periodically and has no expiration date. • Airport terrain - The airport terrain database contains detailed airport terrain data. It is updated periodically and has no expiration date. • Obstacle - The obstacle database contains data for obstacles, such as towers, that pose a potential hazard to aircraft. Obstacles 200 feet and higher are included in the obstacle database. It is very important to note that not all obstacles are necessarily charted and therefore may not be contained in the obstacle database. This database is updated on a 56-day cycle. Obstacles will still be shown after the database has expired. • SafeTaxi - The SafeTaxi database contains detailed airport diagrams for selected airports. These diagrams aid in following ground control instructions by accurately displaying the aircraft position on the map in relation to taxiways, ramps, runways, terminals, and services. This database is updated on a 56-day cycle. SafeTaxi will still be shown after it has expired. • FliteCharts - The FliteCharts database contains procedure charts for the United States only. This database is updated on a 28-day cycle. If not updated within 180 days of the expiration date, FliteCharts no longer functions. Since these databases are not stored internally in the GDU 620, a Supplemental Data Card containing identical database versions must be kept in each display unit for dual installations. After subscribing to the desired database product, the database product will need to be downloaded to a Supplemental Data Card. Insert the Supplemental Data Card into the card slot shown in Figure A-1. The upper slot is typically used for updating the navigation database and is then normally left open. The card may be inserted in either slot. The Supplemental Data Card should not be removed except to update the databases stored on the card. Sec 5 & Alerts Annun.
