GENERAL INFORMATION
1.0 INTRODUCTION
This manual contains information relative to the physical, mechanical, and
electrical characteristics of the BENDIX/KING KRA 405B. Installation and
operating procedures are also included. Information relative to the
maintenance and procurement of replacement parts may be found in the KRA
405B Maintenance Manual Part Number 006-15536-00XX (XX = Highest
Revision).
NOTE: The KRA 405B System consists of four modules: the Radar Altim-
eter (Receiver/Transmitter), the Radar Altimeter Indicator, the
Radar Altimeter Antennas (2 each), and the CM 2000 Configuration
Module (optional). The system is positioned as a replacement
for the KRA 405 Radar Altimeter System.
The preferred configurations utilize the following components:

Some part numbers may not be currently available. Consult the current
Honeywell catalog or contact a Honeywell representative for equipment
availability. The KRA 405B System also may consist of previously TSO
certified components from the following list. However the use of any
configurations other than the preferred configuration will result in
reduced functionality of the system.
Upon use of the above antennas or any other configurations, the STC
certification will be the sole responsibility of the customer and/or the
installing agent. Please contact a field representative for additional
information.
1.1 DESCRIPTION OF EQUIPMENT
The KRA 405B Radar Altimeter System provides the pilot with dependable,
accurate AGL (altitude above ground level) information during the approach
phase of a flight. The system has the capability of alerting the pilot
when a predetermined altitude (decision height) is reached. The system
also provides altitude information to the flight control system during the
approach.
The KRA 405B Radar Altimeter (P/N 066-01153-0202), in addition to
providing an ARINC 552A output for Auxiliary Out 2, has the ability to
take a DH input from an EFIS or KNI 415/416 and generate an audio signal
(refer to section 1.3. C. KRA 405B RECEIVER/TRANSMITTER for tone generator
circuit specifications).
The KRA 405B Radar Altimeter (P/N 066-01153-2001/-4001) provides enhanced
accuracy (±2 feet) below 100 feet using the digital 429 Buss labels 164
and 165.
Both KRA 405B versions P/N 066-01153-0101 and P/N 066-01153-0202 with
software 01/04, 02/04 or higher will not report negative values of
altitude on the ARINC 429 digital bus unless expressly configured to do
so. This feature is required for installations with Honeywell EFIS 40/
50. One of these two unit versions (-0101 or -0202) must be used when
interfacing the digital output of the KRA 405B to equipment which expect
non-negative values.
The KRA 405B determines the altitude above ground level (AGL) by
transmitting a signal to the ground then processing the reflected signal.
The altimeter outputs the altitude information as analog voltages and in
ARINC 429 digital format.

KRA 405B RADAR ALTIMETER INSTALLATION MANUAL
Page 1-3
006-10536-0010 Rev. 10 Oct/2005
The KRA 405B Radar Altimeter System consists of the KRA 405B Receiver/
Transmitter, the KNI 415 or KNI 416 Indicator, and two (2) KA 54A Antennas.
The entire system is solid state except for a servo mechanism and relay
in the Indicator.
The KRA 405B Radar Altimeter replaces the KRA 405 altimeter. The KRA 405B
is electrically compatible with the same indicators and antennas as the
KRA 405.
NOTE: The connectors for KRA 405 and KRA 405B are not compatible.
