MCS--4200/7200 Multi--Channel SATCOM System
(11) TROUBLE SHOOTING DATA Page
(a) General
1
Access to this page is from the SAT--N (i.e., SATCOM MAINTENANCE)
page. The purpose of this page is to display Class 1 and 2, Level 1,
diagnosed failures reported during the last leg and previous legs. See
Figure 6-13 for example pages.

The Trouble Shooting Data pages display the class 1 and 2 last leg and
previous legs failure details. Failures are displayed in chronological order
(i.e., the most recent detected failure last) with one failure displayed per
page. Flight leg display order is reverse chronological (i.e., flights go back in
time while failures for each individual flight go forward in time). The number
of pages depends on the number of failures to report (up to 64 flight legs or
99 pages).
