7 ADJUSTMENT/TEST
7.1 ADJUSTMENT
The EGPWS does not require any adjustments.
7.2 TEST
Line maintenance testing for the EGPWS consists of functional verification of the EGPWC and associated
interfaces. For EGPWC functional verification, see the Fault Isolation Section 3. Associated interfaces are verified
through EGPWS ground tests as described in the following section.
7.2.1 EGPWS GROUND TESTS
All EGPWS Ground Tests are developed by the installer to meet aircraft specific interfaces. Examples of Ground
Test are available from Honeywell via the EGPWS website. To obtain a copy of a sample Ground Test Procedure,
