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.
JEPPESEN
®
NOTE: After performing a Jeppesen database update, verify all flight plans
(routes) are current. If there is an obsolete Jeppesen aviation point in a saved
route, the route is locked and unusable. A new route with current Jeppesen
database points will need to be created.
The Jeppesen Navigation Database (NavData) is updated on a 28-day cycle. The
following information is provided from the Jeppesen database:
• 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.
• Weather—frequencies associated with an airport (ASOS, ATIS, and AWOS).
• VORs—identifier, facility name, city/state/country, location (latitude/longitude),
frequency, service volume (high, low, terminal), and type (such as VOR-DME,
TACAN, and VORTAC).
• NDBs—identifier, facility name, city/state/country, location (latitude/longitude),
and frequency.
