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. Associated interfaces are verified through EGPWS ground tests as described in the following sections.
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.

9 CLEANING/PAINTING
9.1 GENERAL
The EGPWS does not contain any elements that required cleaning or painting on the aircraft. Any cleaning or painting of the EGPWC should be performed by an authorized EGPWS repair facility.
10 REPAIRS
10.1 GENERAL
No on-aircraft repairs are identified for the EGPWS. If a problem is found with a unit, remove and replace the unit per the removal and installation procedures and route the unit to an authorized repair facility for repair.
APPENDIX A: WINVIEWS
WinVIEWS (Windows Virtual Interface to the Enhanced Warning System) is a software tool developed by Honeywell to monitor or view values within the EGPWC, and perform certain test interface functions.
Overview: The WinVIEWS software provides a monitor function that does not alter the operation of the EGPWS. The monitoring of the values assists in the testing of the EGPWS by allowing the operator to quickly determine if the correct signal and scaling is being used by the EGPWS. Additionally, WinViews provides a detailed status of the software configuration and input signals, which enables quick identification of system anomalies. WinVIEWS is also utilized for programming the Configuration Module in MK VI and MK VIII applications.
