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The information stored in the database eventually becomes out of date; therefore, to provide a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.

1.4.5 DATABASE
The KLN 94 is supplied with two different kinds of databases:
1) NAVIGATION DATABASE
This is required to be current for IFR non-precision approaches. Our navigation database is
available on a twenty-eight day cycle.
2) CARTOGRAPHY DATABASE
This includes features such as roads, rivers, railroads, etc. and is provided for reference only.
Cartography database updates are available on a less frequent basis than the navigation
database updates. Updating the cartography database will require a cartridge exchange.
The KLN 94 navigation database cartridge and diskettes are available for three separate
geographic areas. Database cartridges are available only for users in the United States Of
America and Canada. Diskettes are available to all users. Also database files can be dowloaded
via the Internet at the following address: http://www.gpsdatabase.com
NOTE
YY represents the year of the database cycle.
CC represents the cycle of the database.
1.5 ACCESSORIES REQUIRED, BUT NOT SUPPLIED

A KA 33 Cooling Kit or equivalent is required for the KLN 94 installation.

1.5.2 Indicators and HSIs
NOTE
The KPI 553A/553B DME distance display is not compatible with
the KLN 94.
The KPI 553A models that do not have an OBS knob on the
indicator were special for the KNR 665 system and are not
compatible with the GPSs.
1.5.3 CDI Indicator with "MSG" and "WPT" Annunciators
Some stand alone CDI indicators are available with WPT/MSG annunciators built in. One
commonly used is the Model MD40-39, manufactured by Midcontinent Instrument, telephone
[phone]. These devices have no resolver interface. The use of an OBS resolver will
reduce pilot workload.
1.6 OPTIONAL ACCESSORIES
1.6.1 PC Interface Kit
The navigation database may be loaded directly from the PC to the KLN 94 installed in an aircraft
bymeans of the bezel jack(refer to Section 2.4.4.8 for details). To utilize the bezel jackfor loading
of the database, order kit part number 050-03612-0000.
If the installation was previously a KLN 89B installation and utilized an external jack, order
interface kit P/N 050-03213-0000 in order to load the navigation database from a personal
computer. The kit contains a ready to use cable which connects between the aircraft connector
and the computer’s 9 pin or 25 pin serial connector. The kit is necessary whether the user is
loading from a Honeywell diskette or a database obtained via the Internet.
The cartography database is contained in the Sandisk cartridge. The cartography data is not
updated as frequently as the navigation data.

It is necessary to swap cards to update the cartography data. Updating the navigation database
will not compromise the cartography database.
Laptop computers used to load the database require the following:
1. IBM compatibility
2. An available Com 1,2,3, or Com 4 serial port
NOTE
The PC must be fully IBM compatible and must have a 3.5" high
density diskette drive, If the database is loaded from a diskette sent
from Honeywell. For more information, contact Honeywell Product
Services by telephoning [phone].
1.6.2 Annunciators and Switch/Annunciators
(Refer to I.B. 363 for additional information pertaining to switch/annunciators for GPS systems)
The devices shown below are Eaton 582/584 series switch/annunciators and are representative
of those used in our original certification. They were chosen because of their excellent sunlight
readable characteristics and meet or exceed the requirements of Advisory Circular 20-138.
These are high quality devices and we encourage their use. However, there are other
comparable devices on the market that may be substituted at the installer’s/customer’s choice.
These switch/annunciators are available through Honeywell Service Stock or direct from our
supplier, LCOMP Inc. It is advantageous to order direct from LCOMP, if possible, in order to avoid
additional price mark-ups. On international orders, it may be necessary to order through
Honeywell as LCOMP, at the time of this publication, is not prepared to handle international
orders. The address and telephone numbers for LCOMP are listed as follows:
LCOMP Aerospace Controls [phone] Telephone
c/o Carlton-Bates Co. [phone] Toll Free
9214 Bond St. [phone] Fax
Overland Park, KS 66214
NOTE
The switch/annunciators listed below in many cases show two
numbers. The part numbers that are shown in parentheses are
devices previously called out and may be used until supply is
depleted. The 031-00785-XXXX are the preferred
Switch/Annunciator assemblies.
