SECTION III: APPENDIX
THE APPENDIX INCLUDES THE TEST FUNCTION, A
GLOSSARY OF TERMS AND RECOMMENDATIONS FOR
POST FLIGHT REPORTS.
FUNCTIONAL AND AUTOMATIC SELF TEST
The Mode S transponder Functional Test determines the operational
status of the entire system. The test is initiated by rotating the func-
tion selector knob on the Transponder Control Panel to the TEST
position.
Thereafter, the test continues automatically for a period of approxi-
mately eight seconds. During the test the transponder function is
inhibited. When the knob is held for longer than eight seconds the
system remains in test until it is released.
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 system has occurred, give Maintenance as much
specific information about the problem as possible. Avoid phrases
such as “Transponder 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.
