One reason the KLN 900 is such a powerful navigation
system is because of its extensive database. A database
is an area of electronic memory used to store a large cat-
alog of navigational and aeronautical information.
2.1 FUNCTIONS OF THE DATABASE
The database provides two primary functions. First, it
makes pilot interface with the GPS sensor much easier.
Rather than having to manually look up and then enter
the latitude and longitude for a specific waypoint, it allows
you to merely enter a simple waypoint identifier. The
database automatically looks up and displays the latitude
and longitude associated with the identifier. It’s obvious
that the database saves a lot of tedious latitude/longitude
entry and also greatly reduces the potential for data input
mistakes.
The second function of the database is that it serves as a
very convenient means to store and easily access a vast
amount of aeronautical information. Want to know the
tower frequency or the length of the runways at a specific
airport? No need to look them up in a book - just turn a
couple knobs and display the information right on the KLN
900.
2.2 DATABASE COVERAGE AREAS AND
CONTENTS
The International Civil Aviation Organization (ICAO) and
Aeronautical Radio, Inc. (ARINC) break the world into the
ten geographic regions shown in figure 2-1.
The KLN 900 Americas data base contains aeronautical
information for the group of ICAO regions consisting of
Canada, USA, Latin America, and South America. The
KLN 900 Atlantic data base provides information for the
ICAO regions Europe, Africa, East Europe, and Mid East.
Likewise, the Pacific data base contains information for
East Europe, Mid East, Pacific, and South Pacific. The
databases for the KLN 900 have a primary and a sec-
ondary coverage area. The primary coverage areas are
indicated in figure 2-1 and contain more detailed informa-
tion. The secondary area contains less detailed informa-
tion for the rest of the world.

NOTE: Previous database versions included an “International” coverage region that included both the
Pacific and the At lantic regions. Due to space constraints, the “International” version has been discontinued.
