EGPWS
Database
The EGPWS adds to these 7 basic functions the ability to
compare the aircraft position to an internal database and
provide additional alerting and display capabilities for
enhanced situational awareness and safety (hence the term
“Enhanced” GPWS).
The EGPWS internal database consists of four sub-sets:
1.
A worldwide terrain database of varying degrees of
resolution.
2. An obstacles database containing cataloged man-made
objects 100 feet or greater in height located within North
America, portions of Europe and portions of the Caribbean
(expanding as data is obtained).
3.
A worldwide airport database containing information on
runways 3500 feet or longer in length. For a specific list of
the airports included, refer to Honeywell document 060-
4267-000 or access
on the Internet at website

4. An Envelope Modulation database containing information
on airport approach and departure profiles to support the
Envelope Modulation feature.
