Tcas system test ok, Tcas system test fail – BendixKing CAS 66A User Manual
Page 53

At the conclusion of a successful Self Test, a synthesized voice
announces:
“TCAS SYSTEM TEST OK”
FAILURE CONDITIONS:
Should a failure be detected during self test, the audio message says:
“TCAS SYSTEM TEST FAIL”
A “TCAS” flag will be annunciated on the traffic display. A self test fail-
ure may indicate that the auxiliary equipment required for TCAS is not
operational. Check the associated equipment.
If the traffic display is a radar indicator, the appropriate failure mes-
sage will be displayed. See WX & TCAS Message Format in Section
II: Controls and Displays.
Should a VSI failure be detected at any time, the VSI flag will appear
on the TA/VSI (IVA 81A/C/D). A “VSI” flag is not caused by the TCAS
processor.
CP 66A/B CONTROL PANEL TEST
Pressing the TST button on the CP 66A/B initiates a comprehensive
TCAS self test lasting approximately eight seconds. The system will
return to the previously selected modes when the test is complete.
IVA 81A/C/D & TID 66A/D OPTIONAL LAMP TEST
The optional lamp test produces an array of traffic in the pattern
shown. The climb/descend color bands alternate between green and
red, lasting for two seconds each. The bands are blank for a one sec-
ond interval in between.
Note: The VSI function of the TA/VSI ( IVA 81A/C/D) will not be
observed during the lamp test.
RADIO ALTIMETER
If RALT is installed and is inoperative, TCAS will be Inoperative.
