EGPWS Functions and Features
43
Regional Database: Pacific (shaded areas)
Runway database information in the GA-EGPWS computer contains all
known public runways that are 2000 feet in length or longer. This run-
way data is used to adjust the alerting and warning functions of the sys-
tem so as to provide a dynamic system that is essentially free of nui-
sance or unwanted warnings. A list of runways in the database can be
accessed at the Internet website: http:\\ www.egpws.com. A list of the
most recent database versions available for the GA-EGPWS can also be
found there.
TERRAIN INHIBIT SWITCH
The GA-EGPWS requires the installation of a "Terrain Inhibit" switch as
part of the system installation. When engaged by the pilot, this switch will
inhibit all visual and aural alerts and warnings associated with the GA-
EGPWS. Also, an external annunciator lamp is illuminated and a mes-
sage will be displayed indicating “Warnings Inhibited”. The terrain dis-
play, if installed, remains operational.
The purpose of the "Terrain Inhibit" switch is to allow aircraft to operate
without nuisance or unwanted warnings at airports that are not in the
system database. Examples might be private airports or those with run-
ways shorter than 2000 feet. Additionally, there may be some "VFR-
only" airports where unique terrain features are in close proximity to the
runway, and the "Terrain Inhibit" may be used when operating in good
VFR conditions. The "Terrain Inhibit" switch should be NOT engaged for
normal operations.
