TCAS TEST
The TCAS self-test is activated through the RMU TST button and may
be performed on the ground or in flight. TCAS operates normally if not
tested.
To test the system proceed as follows:
− On the RMU radio page, place the yellow cursor box in the
ATC/TCAS window. On the MFD, set TCAS mode.
− Press and hold for 7 seconds the RMU TST button.
− A white TCAS TEST message is presented on the MFDs and
PFDs.
− A TCAS TEST aural warning sounds.
− The Master Warning lights flash.
NOTE: Some airplanes don’t have the Master Warning light
flashing during the test.
− The MFDs show a traffic test pattern, which permits the
checking of each of the existing intruder symbols, i.e., a hollow
blue diamond, a solid blue diamond, a solid amber circle and a
solid red square.
− On the PFDs, the VSI shows red and green arc zones.
− At the end of the test, the RMU shows a green TCAS PASS
message and a TCAS TEST PASS aural warning will sound.
