R  The purpose of this item is to present the fault messages 
R  (class 1 and 2, internal and external) that appeared during the 
R  previous flights. 
R  When no fault has been detected during the last 63 flights, the 
R  NO FAULT DETECTED message is displayed. 
R  - LRU IDENTIFICATION 
R  The purpose of this item is to present the Part Number (PN), 
R  the Serial Number (SN) and the Software Number (SW/N) of the 
R  component. 
R  - TROUBLE SHOOTING DATA 
R  This item allows to analyze the snapshot of the recorded 
R  failure to detect the software bugs. 
R  - CLASS 3 FAULTS 
R  The purpose of this item is to present the class 3 fault 
R  messages that appeared during the last flight. 
R  There is no date and no failure classification. 
R  - GROUND REPORT 
R  The purpose of this item is to present the class 1, 2 or 3 
R  internal failures when they are detected on ground. 
R  - CONFIGURATION DATA 
R  The purpose of this item is to present in three pages, each 
R  formatted differently, the current configuration and discrete 
R  data and format the data for display on the MCDU. 
R  - TEST 
R  The activation of this manual test shall only be allowed on the 
R  ground. The results of the test are transmitted to the CFDIU 
R  but are not memorized.

 A. CFDIU Interface
 (1) BITE description The BITE facilitates maintenance on in-service aircraft. It detects and identifies a failure related to the ATC system. The BITE of the ATC transponder is connected to the CFDIU. The unit tested is the ATC transponder. The BITE:
 -transmits permanently ATC system status and its identification message to the CFDIU
 -memorizes the faults which occurred during the last 63 flight legs
 -monitors data inputs from the various peripherals (FMGC, ADIRU, ATC CTL UNIT and CFDIU)
 -transmits to the CFDIU the result of the tests performed and self-tests
 -can communicate with the CFDIU through the menus. The BITE can operate in two modes:
 -
the normal mode

 -
the interactive mode.

 (a) Normal mode During the normal mode the BITE monitors cyclically the status of the ATC system. It transmits its information to the CFDIU during the flight concerned. In case of fault detection, the BITE stores the information in the fault memories. These items of information are transmitted to the CFDIU every 100 ms by an ARINC 429 message with label 350.

 (b) Interactive mode: The interactive mode can only be activated on the ground. This mode enables communication between the CFDIU and the ATC transponder BITE by means of the MCDU. (Ref. Fig. 012B, 013A, 014A, 015A, 016A, 017A, 018, 019, 020) All the information displayed on the MCDU during the BITE TEST configuration can be printed by the printer. The ATC interactive mode is composed of:
