ND image The ND must display the images corresponding to the four types of intruders: Other, Proximate, TA and RA. The shapes and colors of the traffic symbols are:
-
white outlined diamond for Other traffic
-
white diamond for Proximate traffic
-yellow circle for TA traffic
-red square for RA traffic
(Ref. Fig. 032B)

PFD image At the beginning of the test sequence, green and red sectors must appear sequentially on the vertical speed scale of the PFD. Then a resolution advisory display is shown. (Ref. Fig. 032B)

Fault indication At the end of the test sequence, the system generates a synthesized voice message:
TCAS SYSTEM TEST OK
if the system operates correctly or:
TCAS SYSTEM TEST FAIL
if an anomaly has been detected. In this case the NDs, the PFDs and the ECAM show the fault messages described in Para. 6.G.(5), (6) and (7). In addition, two windows on the front of the TCAS computer display a code identifying the failed component according to the table below:
-------------------------------------------------------------------------------| CONTROL/ | LOCATION | FUNCTION | | INDICATING | | | |------------------|-------------|--------------------------------------------| | TTR PASS | Front panel | Comes on to indicate TTR has passed self-| |(indicator light) | | test | | TTR FAIL | Front panel | Comes on to indicate TTR has failed self-| |(indicator light) | | test | | XPNDR | Front panel | Comes on to indicate transponder or data | |(indicator light) | | link interface failure | | UPPER ANT | Front panel | Comes on to indicate upper TCAS antenna | |(indicator light) | | failure | | LOWER ANT | Front panel | Comes on to indicate lower TCAS antenna | |(indicator light) | | failure | | RAD ALT | Front panel | Comes on to indicate lack of radio | |(indicator light) | | altimeter data | | HDNG | Front panel | Comes on to indicate lack of heading data | |(indicator light) | | | | R/A | Front panel | Comes on to indicate RA indicator failure |

**ON A/C 051-099,
Post SB 34-1159 For A/C 051-054,
A. Self-Test A quick check of the correct operation of the TCAS installation can be performed by activating the FUNCTIONAL TEST function:
-either by pressing the pushbutton switch on the front of the TCAS computer
- or through the CFDIU by applying the procedure TCAS functional test on the MCDU. The self-test sequence checks the main functions of the computer and transmits to the displays:
-resolution advisory characteristics (0 ft/mn advisory, up corrective advisory, don't descend, don't climb > 2000 ft/mn, rate to maintain) on label 270
-label frames 130, 131, 132 containing the data for each of the four intruders according to the following table:
--------------------------------------------------------------------------| INTRUDER | TYPE | RANGE | REL ALT | BEARING | VERTICAL RATE | | | | (NM) | (FEET) | (DEG) | | |------------|--------|---------|-----------|-----------|----------------| | 1 | RA | 2.00 | +200 | +90 |no vertical rate| | 2 | TA | 2.00 | -200 | -90 |climbing | | 3 | PROX | 3.625 | -1000 | +33.75 |descending | | 4 | OTHER | 3.625 | +1000 | -33.75 |no vertical rate| --------------------------------------------------------------------------
