BASEMAP
The basemap database contains data for the topography and land features, such as
river, lakes, and towns. It is updated only periodically, with no set schedule. There is
no expiration date.
AIRPORT DIRECTORY DATABASES
The AOPA Airport Directory provides data on airports and heliports throughout the
U.S. and it is updated on a 56-day cycle. Detailed information for over 5,300 U.S.
airports, along with the names and phone numbers of thousands of FBOs can be
viewed. This service allows the pilot to plan an overnight, choose fuel stops, find
ground transportation, etc.
Optional airport directory databases such as AC-U-KWIK are also supported. AC-
U-KWIK provides complete listings of FBOs, charter companies, fuel suppliers, ground
transportation, maintenance and catering services at public airports across the world.
NAVIGATION DATABASE
The G3X includes an internal navigation database that provides location and facility
information for thousands of airports, VORs, NDBs, and more. Updates to the navigation
database are available every 28 days online (www.fly.garmin.com). There are two
navigation database products available: the Jeppesen Navigation Database, which
is sourced by Jeppesen, and the US VFR Navigation Database sourced by AeroNav
Products, a division of the FAA.
NOTE: Although the Jeppesen Navigation Database and the US VFR Navi-
gation Database contain much of the same information, pilots may notice
differences in behavior, nearest list functionality, direct-to functionality, and
map page display due to data content variations. The US VFR Navigation
Database, by AeroNav Products, does not contain any approach data.
• *Airport—identifier, facility name, city/state/country, latitude/longitude, field
elevation, available fuel types, runway designations and layout, runway surface,
runway length, runway width, runway lighting, communication frequencies, and
published approaches (Jeppesen Navigation Database only).
• Weather—frequencies associated with an airport (ASOS, ATIS, and AWOS).
