MK VI & MK VIII EGPWS Pilot Guide
The EGPWS provides both audio and visual outputs.
Audio outputs are provided as specific alert phrases and altitude
callouts or tones provided by an EGPWS speaker and via the cock-
pit Interphone system for headset usage. Several audio output
levels are available, they are established during the installation of
the EGPWS. These EGPWS audio outputs can be inhibited by oth-
er systems having higher priority (i.e., stall warning) or cockpit
switches in some cases. The EGPWS also has the ability to inhibit
other system audio outputs such as TCAS.
Visual outputs provide discrete caution and warning alert and
status annunciations. Terrain Display video is output to a com-
patible display system when available and enabled.
The discrete visual alerts coincide with audio caution and warning
alerts to achieve an optimum terrain alerting capability. Status
annunciations provide information to the flight crew about the
status of the EGPWS (e.g., GPWS INOP) or activation of selected
functions. Terrain video is generated by the EGPWS based on the
aircraft current position relative to the surrounding terrain. This
video is presented to a Weather Radar indicator, EFIS display, or a
dedicated Terrain Display Unit (TDU).
The EGPWS uses the data stored in the Configuration Module to
define the installation configuration and option selection. The
EGPWS has been designed for maximum flexibility while being
tailored to specific aircraft equipment, sensors, and displays.
The following are standard features of the EGPWS:
• EGPWS Self-Test – Cockpit switch initiates EGPWS Self-Test
on the ground. Typically part of EGPWS "GPWS", or "PULL
UP" warning (red) lamp.
• Glideslope Cancel – Cockpit switch cancels Mode 5 Glides-
lope alerting. Typically part of EGPWS "BELOW GS", or
"GPWS" caution (amber) lamp.
• TAD and TCF Inhibit – Cockpit switch to disable all TAD and
TCF functions.
The following are optional features of the EGPWS:
• Altitude Callouts – Selects desired altitude callouts from a
menu of options.
• Audio Output Level – Selects desired audio output level
from a menu of options.
