Description

• An Aural Declutter feature reduces the repetition of warn-
ing messages. This feature is optional, and may be disabled
by system program pins during installation.
• Geometric Altitude, based on GPS altitude, is a computed
pseudo-barometric altitude designed to reduce or eliminate
altitude errors resulting from temperature extremes, non-
standard pressure altitude conditions, and altimeter
miss-sets. This ensures an optimal EGPWS alerting and dis-
play capability.
Some of these features have been added to the EGPWS as the
system evolved and are not present in all Enhanced Ground
Proximity Warning Computer (EGPWC) part numbers. For spe-
cific effectivity, refer to an applicable Airplane Flight Manual
(AFM) or EGPWS Airplane Flight Manual Supplement (AFMS) or
contact Honeywell for assistance.
The EGPWC is packaged in a 2 MCU ARINC 600-6 rack mounted
enclosure weighing less than 8 lbs. No special vibration isolation
mounting or forced air-cooling is required.
115 VAC (400 Hz.) or 28 VDC versions of the EGPWC are avail-
able. Units are also available with an internal GPS receiver for
required GPS data when another GPS source is not available.
