Additional EGPWS Information
tions, “Geometric Altitude” may have errors during rapid climbs or
descents in non-ISA conditions. This may affect alerting/warning times
and proper altitude reference on the Terrain Display.
* The Terrain, Obstacle and Runway database information is not all-
inclusive.
* The GA-EGPWS “Look-Ahead” alerting and warning, and Runway
Field Clearance Floor (RFCF) functions are gradually “de-sensitized”
as an aircraft nears a known runway. Aircraft operating in close proxim-
ity to known runways may experience very short or no advance warn-
ings with respect to terrain or obstacles in this area. (See sections on
GA-EPWS “Look-Ahead” and RFCF).
GA-EGPWS CONTINUED AIRWORTHINESS AND
DATABASE UPDATE PROCEDURES
Normal maintenance activities performed on the GA-EGPWS should
follow standard industry maintenance practices. System maintenance
practices may included updating the Terrain, Obstacle and Runway
database. Other maintenance practices, such as re-programming the
Configuration Module, are addressed in the System Installation
Manual. Database load procedures and database update cards are
exclusively supplied by Bendix/King Avionics.
The GA-EGPWS database is contained in a removable card installed
in the top of each unit. It is up the GA-EGPWS customer to determine
if a specific database is applicable to their operation. Honeywell esti-
mates that the GA-EGPWS customer will update their database
approximately once per year. Information regarding new releases and
the content details of the database may be obtained via the internet at
the following sites: www.bendixking.com and www.egpws.com.
Please see the following section, GA-EGPWS Product Support, for
contact information to order database updates.
If possible, clearance to the top of the GA-EGPWS should be provided
to facilitate removal and installation of the terrain database card. The
terrain database card is removed and installed with power NOT
APPLIED to the system. The GA-EGPWS computer may be removed
from the aircraft to extract and install database cards if the mounting
location does not provide enough clearance.
Updating the terrain database is accomplished by:
1. Moving the soft plastic cover over the database card out of the way.
2. Pressing the card ejector button located within the unit.
