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 sys­tem's simplicity, practicality, small size and weight, with a minimum number of
required aircraft sensors, provides a formidable safety value.

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.

NOTE

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.

1.3.2 Basic TAS System

The Airborne TAS system is capable of surveillance of aircraft equipped with tran­sponders (i.e., Mode S and Mode C) able to reply to ATCRBS Mode C interroga­tions 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 Traf­fic 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 bot­tom mounted antenna (monopole or directional antenna which shall provide esti­mated 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

PRELIMINARY - SUBJECT TO CHANGE WITHOUT NOTICE

Rev 0, October/2000 10609I00.ZIPCDL Page1-5

of warning curves which are optimized for some General Aviation operations
which do not require compliance with TSO C151a-class B.

B

B KMH 880/KTA 870

BB

This option is programmed into the EGPWS configuration module during sys­tem 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 opera­tion.

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 Ter­rain 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 operat­ing 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 opera­tion. 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 nor­mal flight characteristics.

c. GPS Sensor

The KMH 880 contains an embedded GPS-XPRESS Card sensor that pro­duces 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 sat­ellites 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 satel­lites’ navigation messages to solve for latitude, longitude, altitude, horizontal
velocity, vertical velocity and current UTC.

B KMH 880/KTA 870

GPS Data can also be supplied via the ARINC 743, 743A and RS 232
(KLN94) interfaces.

A GPS Antenna Splitter could be used in liew of installing another antenna.

B. TAS System

1. TAS Modes of Operation

a. Setup Mode

The system shall be configured using an external PC via the Diagnostic
(RS 232) Interface. Reference the Appendices for the programming proce-

dures.

b. Standby Mode

When the Standby mode is selected, the TAS Processor shall disable
surveillance and tracking operations.

The Standby mode may be activated by any of the following: discrete
selection, self-test, aircraft on ground (configuration option), or system failure.

c. Functional Test Mode

When the Functional Test mode is selected, the unit shall be placed into the

Standby mode and the Functional Test portion of BITE shall be performed.

d. TAS Operation (Traffic Advisory) Mode

When the TAS Operation mode is selected, the TAS Processor shall perform
all the surveillance functions and shall provide for the generation of traffic
advisories . The information conveyed in the traffic advisories is intended to
assist the flight crew in sighting nearby traffic.

e. TAS Processor

The TAS Processor shall provide intruder surveillance and tracking, generat­ing traffic advisories for both Altitude-Reporting and Non-Altitude-Reporting
intruders to display potential conflicts and advisories to the flight crew.

The TAS Processor shall track intruders under surveillance and analyze
range and range rate data, and altitude of the traffic to determine whether
that intruder represents a threat.

B KMH 880/KTA 870

BB

The TAS Processor shall also select "proximate traffic" and "other traffic"
intruders to be displayed on the basis of their altitude relative to own aircraft.
The "other traffic" intruders are those that do not qualify to be TA or proximate
traffic but are displayed.

NOTE

Optional (The TAS Processor may be controlled using discrete inputs).

C. Options

1. Display Option

TSO C151a-class B does not require a display for terrain data, however, if at
all possible, terrain data should be displayed for the aircraft operator. The ter­rain display greatly improves situational awareness. The EGPWS supports
numerous displays including traditional Radar displays as well as mode mod­ern MFD’s.

Installations, which include a display, will also need to provide the EGPWS
with range data via ARINC 429 format.

2. Altitude Monitor Option

The EGPWS has the ability to monitor altitude sources and provide caution­ary messages should an altitude source be suspected of being in error. This
feature compares barometric altitude with GPS altitude and generates a
“Check Altitude” message when an error is detected. This is a highly recom­mended option, which can alert a pilot to problems such as a stuck altimeter
or plugged static port. This option requires no additional hardware and is
enabled during the system installation by programming the configuration
module. This feature can provide both audio and display messages.

3. Outside Air Temperature (OAT) (Recommended)

The EGPWS supports an OAT probe for aircraft operated in cold environ­ments. Very cold air temperatures cause an increase in the density of the air
mass and can result in barometric altimeter errors, both in sensitive altime­ters/encoders and blind encoders. Aircraft normally operated in very cold cli­mates can benefit from the addition of an OAT probe interfaced to the
EGPWS. If the aircraft is equipped with an Air Data Computer which outputs
Digital data with Corrected Altitude on an ARINC 429 port, this can be used
instead of an encoder and external OAT Probe. OAT is programmed into the
configuration module during system installation.
