FAILURE CONDITIONS
Should a VSI failure be detected at any time, the VSI flag will appear.
Should a failure be detected during Self Test, the audio message
says:
“TCAS SYSTEM TEST FAIL”
If the TA display is a Radar Indicator or dedicated display, the appro-
priate failure message will be displayed. (See Fault Message Format
in Section II: Controls and Displays.)
TEST AUDIO INHIBIT
TCAS test audio is inhibited during GPWS and windshear test or
alert.
CTA 81B CLOCKWISE TEST POSITION
The CTA 81B function selector is moved to the right hand test posi-
tion (switch fully clockwise) to test the ATCRBS transponder. During
the test, segments of the Transponder Control Unit display window
and the ATC Fail lamp illuminate.
POST FLIGHT REPORTS
If a failure of the TCAS system has occurred, give Maintenance as
much specific information about the problem as possible. Avoid
phrases such as “TCAS inop.”
Provide information in terms of fault lights lit, audio announcements,
test pattern discrepancies and screen annunciations that indicate
which unit was observed to have failed.
