3. Verify that EGPWS inoperative annunciations are
extinguished. If an inoperative annunciation is indicated,
perform the EGPWS Self-Test (below) and then seek
corrective action if the inoperative condition persists.
4. If a terrain display is enabled, select terrain to be displayed.
5. Momentarily depress the EGPWS Self-Test switch.
When a Self-Test is initiated, the EGPWC first checks for any
configuration (installation or database) errors. If any are
detected it is audibly enunciated and the test is terminated. If
none detected, the test continues through a sequence resulting
in turning on and off all system annunciators, enunciating
specific audio messages, and if enabled, displaying a video test
pattern on the terrain display (see illustration below). Any
functions determined inoperative are also enunciated (e.g.,
“GLIDESLOPE INOP”). The Self-Test terminates automatically
at its conclusion.
The following is a description of the expected results of a typical
level 1 Self-Test. Actual annunciation nomenclature and
sequence may differ depending on the installation.
• GPWS INOP, W/S INOP, and TERR INOP annunciators turn
on.
• Amber caution (“BELOW G/S” or “GPWS”) annunciators
turn on.
• “GLIDESLOPE” is announced over speaker.
• Amber annunciators turn off.
• G/S CANCEL annunciators turn on (if installed).

• G/S CANCEL annunciators turn off.
• Red warning (“PULL UP” or “GPWS”) annunciators turn on.
• “PULL UP” is announced over speaker.
• Red warning annunciators turn off.
• Red Windshear warning annunciators turn on.
• (Siren) “WINDSHEAR, WINDSHEAR, WINDSHEAR” is
announced over speaker.
• Red Windshear warning annunciators turn off.
• Amber Windshear caution annunciators turn on (if
installed and enabled).
• Amber Windshear caution annunciators turn off.
• Red warning (“PULL UP” or “GPWS”) annunciators turn on.
• “TERRAIN, TERRAIN, PULL UP” is announced over speaker.
• Terrain test pattern is displayed (RCD XXXXX indicates
loaded RAAS Configuration Database (RCD) and is shown
only in RAAS enabled installations, TDB XXX indicates
loaded Terrain Database (TDB) and is shown only in
-218-218 or later versions).
• Red warning annunciators turn off.
• GPWS INOP, W/S INOP, and TERR INOP annunciators turn
off.
• Terrain test pattern is turned off.
6. Verify expected indications and enunciations during test, repeating
as necessary noting any erroneous conditions.
A successful test is accomplished if all expected indications are
observed and no inoperative functions or display anomalies are indicated
or observed.
For more specific information, refer to an applicable AFM or
EGPWS AFMS, or contact Honeywell.

The EGPWS provides visual and/or audio alerts for detected:
• potentially dangerous terrain conditions (modes 1 – 4, TCF,
TAD),
• below glideslope conditions (mode 5),
• descent below predefined altitudes or excessive bank angle
(mode 6),
• severe windshear conditions (mode 7)
• Runway Awareness Advisories (RAAS)
These consist of warning, caution, and advisory alerts based on
the detection alert threshold penetration. The following list identifies
the various alerts by type and mode:
ALERT WARN CAUT. ADV.
(SIREN) “WINDSHEAR (3x)” 7
Any “PULL UP” 1,2,TA
“CAUTION WINDSHEAR” 7
“TERRAIN, TERRAIN” 2, TA
“OBSTACLE, OBSTACLE” TA

“SINK RATE” 1
“DON’T SINK” 3
“GLIDESLOPE” 5
“BANK ANGLE” 6
Any RAAS Advisories RAAS
NOTE: Visual and audio indications may vary and procedures provided are
representative. Refer to an applicable AFM or EGPWS AFMS for specific
implementation.
