Level 1
Self-Test
Continued
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.
