This Pilot Guide describes the functions and operation of the
MKV and MKVII Enhanced Ground Proximity Warning System
(EGPWS).
The 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 follow 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 operation of aircraft with
the EGPWS.
The information in this document is intended as a general
explanation of the Honeywell EGPWS. It contains a general
description of system performance assuming identified options
are active, and highlights deviations in system performance
resulting when a feature is disabled.
The EGPWS is a Terrain Awareness and Alerting system
providing terrain alerting and display functions with additional
features.
The EGPWS uses aircraft inputs including geographic position,
attitude, altitude, airspeed, and glideslope deviation. These are
used with internal terrain, obstacles, and airport databases to
predict a potential conflict between the aircraft flight path and
terrain or an obstacle. A terrain or obstacle conflict results in
the EGPWS providing 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 configura-
tion, and optionally provides bank angle and altitude callouts
based on system program pin selection. Detection of severe
windshear conditions is also provided for selected
aircraft types when enabled.
