TCAS SELF TEST
The TCAS self test determines the operational status of the entire TCAS
system. Select self test on the TCAS control panel. Once begun, self
test continues automatically for approximately eight seconds. During
self test, normal TCAS operation is inhibited. For optimum display dur-
ing self test, selection of the 5 nm range is recommended.
If the traffic display is a weather radar indicator and the indicator is
OFF, turn On the indicator before selecting TCAS self test. The warm
up time for weather radar indicators is about five seconds.
During the first few seconds of the test sequence, the traffic display
allows verification of each type of Intruder symbol. The test generates
the symbols arranged as shown. The traffic display annunciates the
word TEST. If the weather radar is in the TEST function, this pattern
appears over the radar test pattern. If in a weather function, this test
appears over the weather.
Use of the TCAS self test function in flight will inhibit normal
TCAS operation for up to 15 seconds. For this reason, the pilot
should use caution when initiating the test in flight.
