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).

E - December 2003 MK V & MK VII EGPWS Pilot Guide 49 • 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.

E - December 2003 50 MK V & MK VII EGPWS Pilot Guide 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.
