FUNCTIONAL AND AUTOMATIC SELF TEST
The Mode S transponder and TCAS Functional Test determines the
operational status of the entire system. The test is initiated by rotating
the function 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 TCAS II and transponder
function is inhibited. When the knob is held for longer than eight sec-
onds the system remains in test until it is released.
If the weather radar indicator is OFF, warm up time for the weather
radar indicators is about 5 seconds.
During the first few seconds of the test sequence, the radar indicator
and the TA/VSI allow verification of each type of intruder symbol. The
test generates the symbols arranged as shown. The Traffic Advisory
Display annunciates the word TEST. If the weather radar is in the
TEST function, this pattern appears over the PPI test pattern. If in a
weather function, this test appears over weather.
Use of the self test function in flight will inhibit TCAS II for up to 8 sec-
onds. For this reason, the pilot should use caution when initiating the
test in flight. Depending upon the installation, self test in flight may be
inhibited.
