6.10.6.1.2 Short Level 1 Self-Test
The short level 1 self-test is a subset of the long level 1 self-test. Short level 1 self-test is intended to provide a confidence,
Go / No Go, test to show that the EGPWS is fully operational. It indicates which modes of the EGPWC are currently
operational and which functions are not available. Short level 1 self-test is initiated immediately following the successful
completion of the self-test preamble. The results are described in Figure 6.10.6-2.
