GENERAL INFORMATION
This manual contains information relative to the physical, mechanical, and electrical characteristics of the BENDIX/KING KLN 90B Global Positioning System (GPS) Receiver. General installation procedures are also included.
The KLN 90B is a panel mounted, long range, GPS based airborne navigation system with a data base. 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 display consists of a right and left page and a status line at the bottom of the display. The information on the left page is controlled by the concentric knobs on the left side of the unit and the information on the right page is controlled by the concentric knobs on the right side of the unit. Present position information will be displayed on the unit CRT or can also be displayed on an EFIS or Radar Graphics unit.
The unit can use its present position information to determine crosstrack error, distance-to-way- point, ground speed, track angle, time to waypoint, bearing to waypoint and advisory VNAV guidance. The internal data base of the KLN 90B contains information concerning airports, VORs, NDBs, intersections, and outer markers throughout the world. Waypoints are stored in the data base by their ICAO identifiers. The ICAO identifiers are in most cases taken directly from Jeppesen Sanderson or government aeronautical charts.
The information stored in the data base eventually becomes out of date; therefore, to provide a means of updating the information, the database is housed in a cartridge which plugs into the back of the KLN 90B. It is designed so that the user may easily remove the old database cartridge and install a current database cartridge. 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 90B refer to the KLN 90B Pilots Guide P/N 006-08773-0000.
1.3.1 ARINC 429 GAMA FORMAT INFORMATION
ARINC 429 is a serial bus interface that provides information to and from the KLN 90B to external equipment. The serial bus conforms to ARINC 429 specifications for electrical characteristics, receiving, and transmission interval. The format of the labels are GAMA 429 format.

WPT/MSG Remote Annunciators
The KLN 90B contains two outputs: 1) Waypoint Alert (WPT) and 2) Message (MSG). Annunciation of these outputs is required for certification purposes. A remote annunciator unit is available to annunciate these outputs and is offered in either 5 V, 14 V, or 28 V versions as shown below. The original design of this unit contained the required (WPT) and (MSG) plus two additional fields (-/-) as it was expected that additional annunciation would be required in the future. It has now been determined, however, that additional annunciation will not be required. Therefore, a new design is being offered that contains only the (WPT) and (MSG) fields which allows improved readability. Both options are listed in the following.

1.Aircraft Logbook Entry
2.Aircraft Installation Requirements
The following interface functions were not required for a VFR KLN 90 but are required for an IFR’d KLN 90B installation.
TSO’d Antenna
The antenna must be a TSO’d KA 91, P/N 071-01545-0200 or KA 92 P/N 071-01553- 0200. If the P/N of the KA 91 is not available, it may be identified by the serial number as the TSO’d antennas have a five digit serial number. If the antenna is a non-TSO’d KA 91, P/N 071-01545-0100, and the KLN 90B is a modified KLN 90, the antenna is eligible for exchange as part of the upgrade program.
xNav Instrumentation
The navigation information (D-Bar, Nav Flag, and To-From) must be displayed on an instrument in the pilot’s panel.
Electromechanical indicators are capable of displaying the variable scale factors of enroute, terminal, and approach modes. If the NAV information is displayed on an EFIS system, it must be capable of displaying variable D- Bar scaling required for GPS approaches. This may require a modification to the EFIS system. (Refer to section 1.5 for a list of typical Nav indicators).

KLN 90B |
NOTE
The KPI 552/553/553A’s interfaced to the KNR 665 digital Gold Crown are not compatible with the KLN 90B.
xOBS Interface
For approach approval, the OBS resolver must be interfaced so that selected course through the HSI/CDI indicator will be sent to the KLN 90B for D-Bar resolution. In mechanical indicators, it will be accomplished by switching the OBS resolver lines; and in EFIS installations, it will be usually through the serial busses. Some EFIS applications may require an adapter. (Refer to section 2.3.6.2.P for OBS resolver interface characteristics).
xSwitch/Annunciators:
NAV/GPS (Switch/Annunciator)
If the navigation information is displayed on a shared primary indicator a switch/annunciator will be required to select and annunciate the source unless the indicator is part of an EFIS system that provides that function.
WPT/MSG (Annunciator)
The required annunciators are "WPT" and "MSG" only. Even though the information is available on the KLN 90B display, a remote annunciator is also required in the pilots panel unless it is accomplished in an HSI/CDI or EFIS display.
GPS CRS, OBS/LEG (Switch/Annunciator)
The KLN 90B may operate in either of two modes, LEG or OBS. In LEG mode, the flightplan legs will automatically sequence as determined by present position. In OBS mode, the active waypoint and inbound or outbound course will be manually selected. The Remote OBS/LEG Switch/Annunciator is recommended for non-precision approaches to reduce pilot workload.
GPS APR, ARM/ACTV (Switch/Annunciator)
The KLN 90B requires a switch/annunciator for arming, disarming, or deactivating the approach mode. It will provide remote annunciation of ARM and ACTV and provide a momentary switch function to arm, disarm, or deactivate the Approach Mode and change the D-Bar scale factors. (Refer to section 1.6.C for typical switch/annunciators).
xAltitude Source
An altitude source is required for IFR certification. The altitude may be derived from a compatible encoding altimeter, some RS 232 air data systems, and most ARINC 429 air data systems. (Refer to figure 2-17 for typical altitude sources).
xIsolation Diodes
KLN 90’s below S/N 1542 did not have isolation diodes on the encoding altimeter inputs.
Page 1-20 |
10521I05.TDC |
Rev 5, April/2003 |
BENDIX/KING |
KLN 90B |
The KLN 90/90A’s upgraded to KLN 90B’s that are below S/N 1542 still will not have isolation diodes and may need to have them added to the installation. If the KLN 90B is without diode isolation and is paralleled with another unit such as a transponder, the combination can cause a loading effect which may result in one or all of the units in parallel being disabled. If the KLN 90B is connected to a dedicated encoding altimeter, the diodes are not necessary.
3.Approved Airplane Flight Manual Supplement
A flight manual supplement will need to be prepared and approved. The supplement may be prepared based on the sample, P/N 006-00835-0000. Refer to Appendix B for information on preparing a flight manual supplement and a copy of the STC approval.
4.Pilot’s Guide
The KLN 90B pilots’ guide must be placed in the aircraft in a location that is accessible to the pilot. The pilot’s guide is P/N 006-08773-0000 and the abbreviated pilot’s guide is P/N 006-08774-0000.
The instructions for continued air worthiness given in the TC or STC approvals for this product supplements or supercedes the instructions for continued air worthiness in this manual.
Most Honeywell products are designed and manufactured to allow “on condition maintenance”. On condition maintenance is described as follows; There are no periodic service requirements necessary to maintain continued air worthiness. No maintenance is required until the equipment does not properly perform the intended function. When service is required, a complete performance test should be accomplished following any repair action. Consult the appropriate Unit Maintenance/Overhaul Manual for complete performance test information.

INSTALLATION
This section contains general suggestions and information to consider before installation of the KLN 90B GPS RNAV. Close adherence to these suggestions will assure optimum performance from the equipment.
The conditions and tests required for TSO 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 standards. The article may be installed only if further evaluation by the applicant documents an acceptable installation and is approved by the Administrator.
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.
2.3.1 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.
In the case of the KLN 90B, 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 90B MECHANICAL INSTALLATION
The KLN 90B 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 90B 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 90B.
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 90B 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.
