MK XXII EGPWS Installation Manual
SECTION I – GENERAL INFORMATION
1.1 Introduction
The Honeywell MK XXII Enhanced Ground Proximity Warning System (MK XXII EGPWS)
provides alerts and warnings to prevent controlled flight into terrain (CFIT).
This Installation Manual must be used in conjunction with the Interface Description
Document (Appendix E) for the MK XXII Enhanced Ground Proximity Warning System (MK
XXII EGPWS) to select features and design the installation for this system.
It is assumed that the user of this document is familiar with avionics installation practices
and helicopter systems associated with the installation and operation of the MK XXII
EGPWS. It also assumes access to pertinent aircraft wiring diagrams, modification
records and manuals.
The information contained herein, together with general procedures outlined in FAA AC.43.13
must be followed carefully to assure a safe, electrically sound, certifiable and operational
installation.
The contents of this document are for information and reference only and must not be
construed as formal FAA approved work authorization.

MK XXII EGPWS Installation Manual
1.5.1 MK XXII EGPWS Computer
The MK XXII EGPWS computer is available under P/N 965-1590-0XX with internal GPS. The MK
XXII EGPWS computer is intended for Helicopters and provides a mixture of analog and digital
interfaces. The type of supported displays is limited and includes some EFIS displays. The terrain
database included with the MK XXII EGPWS computer are North America, South America,
Europe, Eastern Europe, Afr ica, As ia, Pac if ic , Sout h Pac if ic , and Mid dle East regi ons and ar e
comprises of terrain data (6 arc second where available), all known airports, many heliports and
man-made obstacles (North America only).
1.5.2 MK XXII EGPWS Configuration Module
The MK XXII EGPWS Configuration Module is available under P/N 700-1710-001 (Included in
Installation Kits, see section 1.8). The MK XXII EGPWS uses a Configuration Module installed in
the aircraft wiring to store aircraft/EGPWS interface configuration.Specifically, the module comes
prewired and replaces part of the backshell of the (P2) connector that plugs into the front of the
MK XXII computer. The Configuration Module is read by the EGPWS only during power up. The
configuration is copied into Non Volatile Memory (NVM) of the EGPWS. The Configuration
Module is programmable via an RS-232 interface with the EGPWS. The contents of the
Configuration Module can also be read back via the same RS-232 interface.
1.5.3 GPS Antenna
EGPWS installations using the internal GPS require an active GPS antenna and cabling. The
GPS antenna should meet the following qualifications:
Frequency:1575.42 MHz
Impedance:50 ohms
Gain:33dB max, 26.5 dB preferred
Power:5 VDC
Qualification:TSO C129 or C129a or C144
The following GPS antennas are found to be compatible with the EGPWS internal GPS card.
Other GPS antennas may be found compatible, contact EGPWS engineering for assistance. It is
the responsibility of the OEM or owner/operator (and ultimately the regulatory authorities) to
assess the antenna acceptance criteria relative to ARINC, MIL, or other specifications.

1.5.4 OAT Sensor
The OAT sensor is available from Computer Instruments Corp. (CIC) P/N 05257. The EGPWS
uses a separate OAT sensor (Outside Air Temperature) to measure outside air temperature on
CAGE CODE: 97896SCALE: NONESIZE: ADWG NO: 060-4314-225REV: C
SHEET

Honeywell
MK XXII EGPWS Installation Manual
aircraft that do not have another compatible source of outside air temperature. Outside Air
Temperature is used by the EGPWS along with pressure altitude in computing Geometric
Altitude. If Outside Air Temperature is not available, Geometric Altitude is computed using
pressure altitude with a corresponding reduction in accuracy.
Geometric Altitude is computed by the EGPWS to reduce or eliminate errors potentially induced
in corrected barometric altitude by temperature extremes, non-standard altitude conditions, and
altimeter miss-sets. Geometric Altitude also allows continuous EGPWS operation in QFE
environments without crew intervention.
1.5.5 Smart Cable (PCMCIA Interface)
The EGPWS Smart Cable (part number 951-0386-001) is a removable PCMCIA card interface.
The Smart Card is compatible with any Honeywell supplied EGPWS PCMCIA style cards. The
purpose of the Smart Cable in the EGPWS system is for upload of software and databases and
also for download of EGPWS Flight History. The Smart Card loading operation will closely
emulate that of an ARINC 615 Data Loader.
