Test Pattern
Figure 1001
2 After the RA/VSI sequence lamp test, the red and green climb/descend lamps
show a set test command that shows a typical resolution advisory during the
remaining test sequence.
NOTE:
The missing correct vertical speed input causes the VSI flag to come into
the view on the RA/VSI. If a TA/VSI is used, the legend VSI comes into
the view on the display. A TCAS processor failure causes the TCAS flag
to come into the view on the RA/VSI, and the TCAS to come into the view
on the TA/VSI.
(c)
For the aircraft that have TA/VSI
The TA/VSI shows a set Resolution Advisory and the traffic symbol test pattern. A
TEST message is shown.
(d) For the aircraft that have PPI Radar/TCAS or dedicated display:
The PPI or dedicated display shows the TCAS display test pattern and TEST is
shown.
(e) At the correct end of the self-test, the TCAS processor output on the audio bus
starts the synthesized voice message, TCAS System Test OK.
