The ATIMS BITE is used to facilitate the aircraft maintenance in compliance with ABD048 specifications. It detects, identifies and memorizes the internal and external failures related to the ATIMS system: - ATSU internal failures - external interface failures with ATSU peripherals. The ATIMS BITE is ensured by the ATSU which concentrates the failure information provided by the ATSU internal monitoring. This BITE is of type 1 and operates in two modes: - normal mode - MENU mode
(1) Normal mode During the normal mode, the BITE: - monitors the ATSU status - monitors data inputs from the various ATIMS peripherals (FMGC, MCDU, CFDIU,...) - permanently transmits ATIMS system status and its identification message to the CFDIU. In case of fault detection, the BITE stores the information in the fault memories and transmits it to the CFDIU by an ARINC 429 message (Label 356). The BITE memorizes the failures which occurred during the last 63 flight legs.

The BITE information (system report) and the test request (system test function) are available through MCDU menus which allow to communicate with ATIMS BITE via the CFDIU. To gain access to the BITE, it is necessary to use one MCDU (Ref. 22-82-00). All the information displayed on the MCDU during the BITE test configuration can be printed by the printer. ATIMS maintenance menu is only accessible on ground from the general maintenance menu and the SYSTEM REPORT/TEST page. This mode enables communication between the CFDIU and the ATIMS BITE by means of the MCDU.

This report contains the failure messages (internal and external, Class 1 and 2) recorded during the last flight. It is available at the end of the flight. Each failure message is reported with the failure classes defined by the CFDS standard.

This menu enables to display the identification of the various ATIMS components (ATSU and Software packages). It is used to check the uploading of the correct software Part Number: - Part Number and Serial Number of the ATSU (hardware case - FIN 1TX1) - Part Number and Serial Number of the DCDU 1 and DCDU 2 (FIN 2TX1 and 2TX2) - Part Number of the SOFTWARE-ATSU A/C INTERFACE (FIN 20TX) - Part Number of the SOFTWARE-ATSU CONFIGURATION (FIN 21TX) - Part Number of the SOFTWARE-ATSU ROUTER PARAM (FIN 30TX) - Part Number of the SOFTWARE-AOC (FIN 22TX) - Part Number of the SOFTWARE-AOC DATABASE (FIN 24TX) If one component is missing in a given configuration, the corresponding line is not displayed.
