This Pilot Guide describes the functions and operation of the
MK VI and MK VIII Enhanced Ground Proximity Warning System
(EGPWS).
This document is divided into four sections. Section 1 is this
introduction and the following brief description of the EGPWS
and its features. Section 2 provides a functional description of
the EGPWS. This includes descriptions of the various system
modes, Built In Test (BIT) and monitoring functions, and system
features. Section 3 provides general operating procedures to fol-
low when the system gives a caution or warning alert. Section 4
provides definitions of terms used in this manual.
This guide does not supercede FAA approved data, Flight
Manuals, individual Operations Manuals, requirements,
or procedures. Pilots should be thoroughly familiar
with their own company policies, system configuration,
requirements, and procedures with respect to the op-
eration of aircraft with the EGPWS.
The information in this document is intended as a general expla-
nation of the Honeywell MK VI & MK VIII EGPWS. It contains a
general description of system performance assuming identified
options are active, and highlights deviations in system perfor-
mance resulting when a feature is disabled.
The EGPWS is a Terrain Awareness and Warning System (TAWS)
providing basic GPWS functions plus additional enhanced terrain
alerting and display features.
The EGPWS uses aircraft inputs including geographic position, at-
titude, altitude, airspeed, and glideslope deviation. These are used
with respect to internal terrain, obstacle, and airport databases
to predict a potential conflict between the aircraft flight path and
terrain or an obstacle. A conflict will result in the EGPWS provid-
ing a visual and audio caution or warning alert.
Additionally, the EGPWS provides alerts for excessive glideslope
deviation, too low with flaps or gear not in landing configuration,
and optionally provides bank angle and altitude callouts based on
system configuration selection.
