 TROUBLE SHOOTING DATA This function allows to analyze the snapshot of the recorded fault to detect any software bug. Two types of data are displayed:

 -
some correlation parameters which are the date and the UTC hour displayed in clear english,

 -
some snapshot data delivered in hexadecimal code or in clear

 message.
 (Ref. Fig. 040A)

 (7)
 GROUND REPORT This function is used to present class 1, 2 or 3 internal faults when they are detected on ground. These faults differ from those displayed on the LAST LEG REPORT page. The following figure shows examples of internal faults recorded on ground by the TCAS system. The relevant trouble shooting data are displayed by pressing the line key adjacent to the fault indication. (Ref. Fig. 039B)

 (8)
 DISCRETE CONFIGURATION This function is used to present the value or the status of several discretes. A report screen for each data shows the status of the discrete at the time this menu is selected. (Ref. Fig. 041)

 (9) TCAS functional test A TCAS built-in functional test can be initiated by pressing the line key adjacent to the TEST indication on the TCAS maintenance sub-menu. The following sequence is then generated. (Ref. Fig. 042, 043) - the test ends with the display of the following message on the MCDU: TEST OK or TEST FAIL When all the tests are completed and no fault has been detected, the synthesized voice message TCAS SYSTEM TEST OK is announced. If one of the test criteria has not been met, the synthesized voice message TCAS SYSTEM TEST FAIL is announced. Remarks: - this short test permits to check rapidly, on ground, the functionality of the TCAS and particularly that of the PFD/NDs via the DMC. In addition it enables to check correct operation of the synthesized voice message system.
 NOTE : To date, the DMCs cannot present four intruders as specified____ on the instruction page. Only three intruders (RA, TA, PROXIMATE) are shown on the test display. The future Full Time Display will call for their presentation.
 (10) Software configuration follow-up The TCAS has the DATA BASE loading capacity from a portable data loader or an airborne data loader (MDDU) in compliance with ARINC 615 characteristics. Consequently it must be possible to check correct downloading by using the CFDS/MCDU interface. The LRU IDENTIFICATION item displays the downloaded software version reference.
 NOTE : The TCAS is not data loadable.____

 -the test ends with the display of the following message on the
 MCDU: TEST PASSED or TEST FAIL
 -at the end of the functional test the TCAS computer generates a complete sequence of synthesized voice messages. When all the tests are completed and no fault has been detected the computer reports TCAS TEST PASS. If one of the test criteria has not been met, the synthesized voice message TCAS SYSTEM TEST FAIL is announced. Remarks:
