SECTION 6
TESTING/FAULT ISOLATION
1. Overview
A.
General
(1) This section defines the built-in test equipment (BITE) requirements for the MCS
system (i.e., SDU and HPA). Information supplied in this section describes how MCS
system failures are detected, recorded, and reported. See Figure 6-1 for an overview
of the BITE system communications.
(2) System BITE contributes to a number of maintenance functions:
•
Detection of internal and external failures
•
Storage of in-flight failure data
•
Reporting failure status in the air and on the ground
•
Ground test capability for isolating faulty LRUs, performance verification, and
system level testing.
