Hide thumbs


Table of Contents
This Pilot Guide describes the functions and operation of the
MK V and MK VII 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
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 supersede 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 the 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.
What is the
The EGPWS is a Terrain Awareness and Alerting system
providing terrain alerting and display functions with
additional features meeting the requirements of TSO C151b
Class A TAWS.
The EGPWS uses aircraft inputs including geographic
position, attitude, altitude, airspeed, and glideslope deviation.
These are used with internal terrain, obstacles, and airport
runway 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 configuration, 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.
