SECTION I
GENERAL INFORMATION
1.1 INTRODUCTION
This manual contains information relative to the physical, mechanical, and electrical
characteristics of the BENDIX/KING KLN 94 Global Positioning System (GPS) Receiver. General
installation procedures are also included.
1.2 EQUIPMENT DESCRIPTION
The KLN 94 is a panel mounted, long range, GPS based airborne navigation system with a
database. The KLN 94 also provides VFR, IFR enroute, and IFR non-precision approach
functions. The primary purpose of the equipment is to provide the pilot with present position
information and to display guidance information with respect to a flight plan defined by the pilot.
Flight plan information is entered by the pilot via various knobs and buttons on the front panel.
The unit can use its present position information to determine crosstrack error, distance to
waypoint, ground speed, track angle, time to waypoint, bearing to waypoint, and advisory VNAV
guidance. The database of the KLN 94 contains information concerning airports, VORs, NDBs,
intersections, DP/STARs, outer markers, roads, rivers, railroads, lakes, etc., throughout the
database’s coverage area. Waypoints are stored in the database by their ICAO identifiers. The
ICAO identifiers are in most cases taken directly from Jeppesen Sanderson or government
aeronautical charts. The KLN 94 has instrument approach capabilities.
The information stored in the database eventually becomes out of date; therefore, to provide a
means of updating the information, the database is housed in a data card which plugs into the
front of the KLN 94. It is designed so that the user may easily remove the old database and install
a current database. A secondary method of updating the database is by loading the information
via an IBM compatible laptop computer. For more information on availability and cost of updating
the database of the KLN 94, refer to the KLN 94 Pilot’s Guide P/N 006-18207-0000.
