The EGPWS incorporates the functions of the basic Ground
Proximity Warning System (GPWS). This includes the following
alerting modes:
The EGPWS adds to these 6 basic functions the ability to compare
the aircraft position to an internal database and provide addi-
tional alerting and display capabilities for enhanced situational
awareness and safety (hence the term "Enhanced" GPWS).
The EGPWS internal database consists of four subsets:
• Terrain data of varying degrees of resolution.
• Cataloged obstacles 100 feet or greater in height located
within North America, portions of Europe and portions of Asia
(expanding as data is obtained).
• Airport runway data containing information on all runways
2000 feet or longer in length. This value is configurable as
3500 feet in the MK VIII in software load -008 or later. For a
specific list of the airports included, refer to Honeywell docu-
ment 060-4326-000, or 060-4267-000.
This can also be accessed on the Internet at www.egpws.com.
• An Envelope Modulation database to support the Envelope
Modulation feature described later. (This feature not available
in -001 release).
The MK VI EGPWS provides regional database coverage whereas
the MK VIII EGPWS provides a worldwide database . For the MK
VI, the database is divided into three regions referred to as the
Americas Region, Atlantic Region, and the Pacific Region.
