SECTION 1
GENERAL INFORMATION
1.0 INTRODUCTION
This manual contains information relative to the physical, mechanical and electri-
cal characteristics of the KMH 880/KTA 870 Multi-Hazard Awareness System. It
includes the basic guidelines, considerations and recommendations for the instal-
lation and ground checkout of KMH 880/KTA 870 Multi-Hazard Awareness System
and associated components. It is intended to provide the detail required to assist
the installer in preparation for installation and appropriate work instructions to
ensure a proper installation and checkout.
This manual assumes a familiarity with avionics installation practices, with sys-
tems on board the aircraft and access to manuals and regulations commensurate
with the installation of such equipment.
The information contained herein, together with the general procedures outlined in
FAA AC.43.13-1B and AC.4313- 2A should be followed carefully to ensure a safe
and electrically sound system installation.
The contents of this manual are for information and reference use only and must
not be construed as a formal FAA approved work authorization.
It is highly recommended that prior to beginning the installation of the KMH 880/
KTA 870 system that this manual is carefully reviewed. Upon review the necessary
configuration items and system requirements will be identified allowing a speedy
installation.
Operational information is contained in the KMH 880/KTA 870 Operators Manual
supplied with each unit.
1.1 PURPOSE
This manual will describe the detailed system requirements for the Bendix/King KMH 880
Multi-Hazard Awareness System and KTA 870 Traffic Advisory System . The KMH 880
combines TAS (Traffic Advisory System) with EGPWS (Enhanced Ground Proximity
Warning System). The KTA 870 has TAS only.

1.2 APPLICABILITY OF THE SYSTEM MANUAL
1.2.1 Equipment Applicability
This manual is applicable only to KMH 880/KTA 870 Multi-Hazard Awareness Sys-
tem part numbers displayed in the table below:
1.3 SYSTEM DESCRIPTION
1.3.1 Basic EGPWS System
The KMH 880 EGPWS is a revolutionary new step in Controlled Flight Into Terrain
(CFIT) protection. It is capable of producing advanced alerting for prevention of
CFIT accidents. In addition to the alerting protection the system will also produce
a terrain display. This display depicts relative terrain in reference to the lateral and
vertical positions of the aircraft.
The EGPWS is intended for Light Turbine and Piston Aircraft Operations. It has
effective operational performance in providing timely alerts and operational terrain
display to enhance situational awareness. This performance, coupled to the sys-
tem's simplicity, practicality, small size and weight, with a minimum number of
required aircraft sensors, provides a formidable safety value.
NOTE
The EGPWS portion of the KMH 820 is not suitable for helicopter operation.
No Radio Altimeter, Landing Gear or Flap discretes, or Glideslope receiver are
necessary. This significantly lowers the installation costs.
The KMH 880 is a system designed to minimize the system requirements down to
a level economical to the private pilot. It is the central component in the system
providing timely alerts and optional display of impending terrain incursions.
The KMH 880 is a TSO C151A class B compliant system.

1.3.2 Basic TAS System
The Airborne TAS system is capable of surveillance of aircraft equipped with tran-
sponders (i.e., Mode S and Mode C) able to reply to ATCRBS Mode C interroga-
tions in their operational environments. This is a step toward determining
potential collisions and displaying traffic advisory information to the pilot. The TAS
system will interoperate with the U.S. National Standard Air Traffic Control Radar
Beacon System (ATCRBS) and perform reliably out to a range of ten nautical
miles for densities up to 0.08 aircraft per square nautical mile while complying with
all ATCRBS signals-in-space requirements. The TAS equipment will not degrade
either the electromagnetic or the air traffic environment.
When all features are implemented the equipment has the capabilities of the Traf-
fic Advisory System (TAS) defined by TSO-C147.
The TAS system will provide:
(1) An alert to the pilot using an audible and visual advisory of the proximity of
an intruder aircraft.
(2) The range to ± 0.1 nautical mile, altitude (if reported by surveilled aircraft),
and relative bearing of intruder aircraft with maximum installed accuracy of
±30° with high reliability. If the intruder aircraft is transponder equipped,
within ten nautical miles, ± 10,000 feet relative altitude, and TAS is not in
interference limiting, it will be reliably detected and reported.
(3)Timely data that does not lag more than 2 seconds behind the actual rela-
tive position as seen by the pilot during normal flight operations.
(4) Probability of displaying false targets will be less than 2%. If they are dis-
played, they will not persist for more than a few seconds.
(5) No increase of traffic on the Secondary Surveillance Radar radio frequen-
cies in a manner that degrades the ATC system.
(6) Display of indications that do not encourage the pilot to maneuver without
first visually acquiring the other aircraft and determining that a maneuver is
required.
1.3.3 System Components
The KMH 880 Multi-Hazard Awareness System shall be composed of the KMH
820 (TAS/EGPWS Processor), a top mounted directional antenna (KA 815), a bot-
tom mounted antenna (monopole or directional antenna which shall provide esti-
mated bearing of target aircraft), a top mounted GPS antenna (KA 92), and a
Configuration Module (CM 805).

A Multifunctional Display Unit, KMD 540, shall provide control and display of traffic
(via the KAC 504 Traffic Card) and control and display of EGPWS data (via the
KAC 502 Adapter Card). Other displays that are compatible with ARINC 735A
may be used for traffic with this system. See Figure 1-1.
The KTA 870 Traffic Advisory System is similar to the KMH 880 except the KTA
810 Traffic Advisory Unit has only TAS and not EGPWS. The KTA 870 system
does not use a KA 92 GPS antenna. See Table 1-2 and Table 1-3 for a complete
description and part number listing for both systems.

1.3.4 System Operation
A. EGPWS System
1. EGPWS Modes of Operation
a. TSO Mode
The EGPWS has provisions to allow the selection of alerting/warning curves
which comply with the requirements of TSO C151a class B or an alternate set
of warning curves which are optimized for some General Aviation operations
which do not require compliance with TSO C151a-class B.

This option is programmed into the EGPWS configuration module during sys-
tem installation and thus remains specific to the aircraft. Once set up, any
Enhanced Ground Proximity Warning Computer installed in the aircraft will
access the configuration module and provide the appropriate mode of opera-
tion.
NOTE
All aircraft, which are required by Federal Aviation Regulations to have
Terrain Awareness and Warning System (TAWS) comply with TSO
C151a-class B, must be configured with the TSO curves. Additionally,
the alternate Audio Menu must be selected to meet the alert/warning
aural requirements of the TSO.
b. Non-TSO Mode
If this installation is intended to provide the operator with a non-required Ter-
rain Awareness and Warning System to enhance safety of flight, it may be
appropriate to select the Non-TSO Mode of operation. As a general rule,
higher performance aircraft, especially ones flown primarily IFR and operat-
ing into larger airports may find the TSO curves most appropriate. Slower
performance aircraft operating primarily VFR and operating at low altitudes
AGL into small airports may find the Non-TSO curves better suit their opera-
tion. Any installation not required to comply with TSO C151a-class B may
select either the Basic Audio menu or the Alternate Audio menu.
The EGPWS may also be installed in aircraft that do not require FAA approved
TAWS Systems, and may be utilized with an optional set of alerting and warning
parameters that are designed especially for smaller piston aircraft and their nor-
mal flight characteristics.
c. GPS Sensor
The KMH 880 contains an embedded GPS-XPRESS Card sensor that pro-
duces validated navigational position data by continuous signal acquisition
and tracking of the navigational satellite network. The GPS Sensor receives
the C/A code signals transmitted by the satellite network on the L1 frequency
of 1575.42 MHz. The sensor has 8 signal processing channels allowing 8 sat-
ellites to be tracked simultaneously. At least 4 satellites must be in view of the
antenna for the sensor to operate. The GPS Sensor uses data in the satel-
lites’ navigation messages to solve for latitude, longitude, altitude, horizontal
velocity, vertical velocity and current UTC.
