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The information stored in the database eventually becomes out of date; therefore, to provide a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

SECTION II

INSTALLATION

2.1 GENERAL INFORMATION

This section contains general suggestions and information to consider before installation of the
KLN 94 GPS RNAV. Close adherence to these suggestions will assure optimum performance
from the equipment.

NOTE

For aircraft equipped with a KLN 89B that is being replaced by a
KLN 94 refer to Appendix D, Direct Replacement of a KLN 89B with
a KLN 94, at the end of this manual.

NOTE

The conditions and tests required for TSO/JTSO approval of this
article are minimum performance standards. It is the responsibility
of those desiring to install this article either on or within a specific
type or class of aircraft to determine that the aircraft installation
conditions are within TSO/JTSO standards. The article may be
installed only if further evaluation by the applicant documents an
acceptable installation and is approved by the Administrator.

2.2 UNPACKING AND INSPECTING EQUIPMENT

Exercise extreme care when unpacking the equipment. Make a visual inspection of the unit for
evidence of damage incurred during shipment. If a claim for damage is to be made, save the
shipping container to substantiate the claim. The claim should be promptly filed with the
transportation company. It would be advisable to retain the container and packaging material
after all equipment has been removed in the event that equipment storage or reshipment should
become necessary.

2.3 EQUIPMENT INSTALLATION

2.3.1 AVIONICS COOLING REQUIREMENTS FOR PANEL MOUNTED EQUIPMENT

The greatest single contributor to increased reliability of all modern day avionics is to limit the
maximum operating temperature of the individual units whether panel mounted or remote
mounted. While modern day individual circuit designs consume much less electrical energy,
watts per cubic inch dissipated within the avionics unit remains much the same due to the high
density packaging techniques utilized. Consequently, the importance of providing cooling to the
avionics stack is still with us today.

While each individual unit may or may not require forced air cooling, the combined heat load of
several units operating in a typical avionics location will significantly degrade the reliability of the
avionics if provisions for cooling are not incorporated in the initial installation. Failure to provide
cooling to the equipment will lead to increased avionics maintenance costs and may also void the
Honeywell warranty.

Rev. 4, Jan/2003 10599I04.CDL Page 2-1

B KLN 94

In the case of the KLN 94, installation of a KA 33, (P/N 071-4037-XX), or equivalent cooling
system is required. Ram air cooling is not acceptable. For installation information on the KA 33
refer to the KA 33 installation manual, P/N 006-01069-XXXX or Installation Bulletin 258.

2.3.2 KLN 94 MECHANICAL INSTALLATION

The KLN 94 installation will conform to standards designated by the customer, installing agency,
and existing conditions as to the unit location and type of installation. However, the following
suggestions will assure a more satisfactory performance from the equipment.

A. Plan a location on the aircraft panel so that the KLN 94 is plainly visible to the pilot and so that
he has complete access to all front panel controls. Check to be sure that there is adequate depth
behind the panel for the mounting rack and all the connectors and cabling. Be sure that the
mounting location is not close to heater vents or other sources of high heat.

B. Refer to figure 2-3 for the panel cutout dimensions. Mark and cut the panel opening.

2.3.3 ANTENNA SELECTION

The KA 91 and KA 92 GPS active antennas, P/N 071-01545-0200 and 071-01553-0200
respectively, are the designated antennas for the KLN 94.

2.3.4 ANTENNA INSTALLATION CONSIDERATIONS

The antenna should be mounted on top of the fuselage near the cockpit. Avoid mounting the
antenna near any projections, the propeller, and the T-tail of the aircraft, where shadows could
occur. It is recommended that there be a separation of at least 3 ft between the KLN 94 GPS
antenna and any VHF Comm antenna on the aircraft. Antenna baseplate must be level within
± 5° in both axes when the aircraft is in level flight. If the antenna is tilted more than 5° or is
mounted close to other objects that shadow it, loss of some of the satellites will occur and system
performance may be degraded. Antenna cable and connector information, including vendor
information, is listed below. Refer to figure 2-10 (TNC) and figure 2-11 (BMA) for cable/connector
assembly instructions for the 0 to 40 feet category using RG 400/U or RG 142B/U. Refer to

Figure 2-12 (for both TNC and BMA) for the 0 to 80 feet and 0 to 100 feet categories.

NOTE

KA 91/92 nominal gain and noise figures are 26.5 dB and 2.3 dB
respectively. With 0.050 ice on radome, gain will not decrease by
more than 2.0 dB when viewing a satellite from 30° above the
horizon to zenith, as compared to a no ice condition.
