1. General
A. FIDS and BITE Functions in the EIS
The EIS/FWS main computers include Built-In-Test (BITE) functions which perform a permanent monitoring of all the items of equipment involved in the EFIS and ECAM operational functions, and also of the various sources which provide the EIS/FWS with input signals.
The DMCs act as FIDS (Fault Isolation and Detection System) for the DUs and the A/C circuitry (wiring, control knobs, selector switches)...
The FWCs act as FIDS for the SDACs and the ECP, the cockpit loud speakers, and the various controls and the alert lights.
The FAC1 acts as FIDS for the AFS, and particularly for the FCU which includes the EFIS control sections.

B. EIS/FWS Architecture Versus Maintenance Requirements and Basic Operation
The CFDIU provides interface with the BITE resident routines for maintenance and test implemented in the computers, and particularly the DMCs.
The BITE memories store all the detected events concerning the last flights: failures, abnormal disengagements..., with the associated contexts concerning these events: concerned flight leg, date, GMT at the time of the failure....
The DMCs send complete messages corresponding to the failures in plain english language to the CFDIU.
The messages are sent as soon as the failures are detected, isolated and stored in the BITE memory. They are displayed on request on the interactive Multipurpose Control and Display Units (MCDUs), which are located on the center pedestal.
To read them, the crew presses the MCDU MENU mode key on the MCDU.
A menu is offered proposing: FMS, CFDS, AIDS main functions.
A menu is offered proposing: FMS, CFDS main functions.
The crew presses the line key adjacent to the chosen function (CFDS in our case).
The MCDU then displays the list of the LRUs for which a fault has been recorded during the flight, the EIS items of equipment for our concern.
In addition, on the ground, the maintenance teams have the possibility to read the events recorded during the last flight legs, therefore to have an history of the system behaviour, by means of more detailed menus displayed on the MCDUs in the maintenance or menu mode.
These menus are elaborated by the DMCs and sent to the CFDIU. For that purpose, a dialog between the CFDIU and the chosen equipment (DMC 1 or 2 or 3) is made possible by pressing the appropriate line keys on the MCDU, a given key addressing a given item of the displayed DMC menu.
In fact, two modes are provided, the normal mode (or reporting) and the menu mode (or interactive):
The CFDIU permanently addresses through its common bus line the A/C computers and provides them with the following information:
The DMC menus also enable the flight and maintenance crew to perform overall system tests, easily readable and interpretable.

In fact, two modes are provided, the normal mode (or reporting) and the menu mode (or interactive):
- in the normal mode, the following functions are carried out:
. failure detection and analysis
. recording of the failure code and associated failure context (leg, date, GMT...) in the DMC BITE memory
. transmission of the failure messages and associated failure context in plain english language to the CFDIU
. response to the CFDIU controls.
- in the menu mode, which is available on the ground only, a thorough access to the BITE contents is provided through the interactive MCDU which displays the various menus elaborated by the DMCs, in particular:
. main EIS menu with last leg and previous legs report
. full BITE memory dump menu.
The CFDIU permanently addresses through its common bus line the A/C computers and provides them with the following information:
- GMT, flight number, date ... for numbering and marking the events stored in the BITE (system disconnection, failures, ...)
- control words for addressing the A/C computer and requesting its BITE memory contents
- one word for identification of the A/C computer, so that the CFDIU knows the origin of the maintenance message
- several words of characters, encoded per ISO alphabet No. 5, and forming messages in plain engligh language. These messages are a translation of the BITE memory stored events.
They give the faults at the LRU level in flight and at a deeper level on the ground (complete BITE memory dump available through menus).
The DMC menus also enable the flight and maintenance crew to perform overall system tests, easily readable and interpretable.
- Display test
On the ground, on request from the MCDU, a test pattern is displayed on the DUs.
- I/P test
On the ground, on request from the MCDU, a thorough monitoring of all the buses from the various DMC I/P sensors and A/C computers is provided, thus signalling the hidden failures of the DMC sources which are not used in the normal configuration (e.g. FWC2, ...).
- Data Bus test
On the ground, this test is available, to check the links DMC to DU or DU to DMC, or the related input ports.
- DU Backlight status test
This test allows to check the good working conditions of the bulbs of the light box assembly.
- DU Brightness test
This test allows to check the good working conditions of the brightness control system of the DU.
- System test
On the ground, on request from the MCDU, the DMC performs the functional tests of all the internal functions of the system (DMC, DUs, DMC-DUs links).
- Switching test
On the ground, on request from the MCDU, the DMC performs the functional tests of all the switching functions of the system (DMC, DUs, DMC-DUs links and switching links).
2. Failure Detection-BITE Organization
A. Internal Failures
The internal failures are those concerning the EIS items of equipment only, i.e. DMCs, DUs, A/C wiring (including relay boxes and various controls such as knobs, selector switches, pushbutton switches).
The internal failures of the DMC are those which stop the DMC operation and force it to switch to the SYNCHRO mode and to initiate a power on Self-Test.

B. External Failures
The external failures are those concerning the DMC I/P buses, i.e. loss of activity from a given bus, or labels no longer transmitted or seen in the INVALID condition.

C. Fault messages
A bus fault message is of the form:
ADIRU2(1FP2)BUS1 ADR/DMC1(1WT1) where the bus ADIRU2 BUS1 ADR drives the DMC1. The message means the bus is faulty.
When there is only one link between a LRU and the DMC the fault message is of the form ADF1(2RP1)/DMCx(1WTx). The message means ADF1 data is not available.
A bus fault message is of the form:
ADIRU2(1FP2)BUS1 ADR/DMC1(1WT1) where the bus ADIRU2 BUS1 ADR drives the DMC1. The message means the bus is faulty.
When there is only one link between a LRU and the DMC the fault message is of the form ADF1(2RP1)/DMCx(1WTx). The message means ADF1 data is not available.

AA. DMC BITE Memory Features and Organization
The BITE memory is a 2 Kwords non-volatile EEPROM memory, which is physically implemented with the DMC common memory on the PFD DPU.
Only the PFD DPU can get access to the BITE memory to prevent conflicts with other boards.
The DMC BITE is divided into four zones:
ZONE 1: to record EIS internal faults (DMCs, DUs, links) (flight, phases 2 to 9a)
ZONE 2: to record all the external faults (input buses) (flight, same conditions)
ZONE 3: to record the internal faults, but without flight leg history management ((ground, phases 1, 9b, 10) more than 8+30 seconds, 9, 10)
ZONE 4: to record all the internal and external faults in the ground troubleshooting mode.

ZONE 4: to record all the internal and external faults in the ground troubleshooting mode.
3. Operation in the Normal Mode
A. Transmission of Failure Information
In the normal operational mode, i.e. with EFIS and ECAM images normally displayed on the DUs, the failures are automatically transmitted to the CFDIU as soon as they are detected, isolated and stored in the BITE memory, but only in the so-called flight phases, i.e. from 2 to 9a.
On the ground, in phases 1, 9b and 10, only the EIS internal faults are recorded, but they are not transmitted. They can be read only in the menu mode, by a dump of the zone 3.
However, the DMC still continues sending the failure messages of the last flight leg, i.e. those recorded in the flight phases of the last flight leg.
The DMCs constantly know which failures they must record and in which BITE memory zone they must store them by decoding the command code transmitted by the CFDIU on its label 227.
In the normal operational mode, i.e. with EFIS and ECAM images normally displayed on the DUs, the failures are automatically transmitted to the CFDIU as soon as they are detected, isolated and stored in the BITE memory, but only in the so-called flight phases, i.e. from 2 to 9a.
On the ground, in phases 1, 9b and 10, only the EIS internal faults are recorded, but they are not transmitted. They can be read only in the menu mode, by a dump of the zone 3.

4. Operation in the Menu or Maintenance Mode
A. Transmission of Maintenance Information
In the menu mode, which is accessible on the ground only, the DMCs stop sending the failures of the last flight leg.
Should a failure occur when the A/C is in the ground phases and with the DMC operating in the menu mode, the DMC reverts to the normal mode and the detected failure is stored in the zone 3 if the A/C is in the ground phases. The DMC resumes sending the failure messages of the last flight leg.

B. Menus - Complementary Failure Information
If the DMCn is selected, with n = 1, 2 or 3, the CFDIU sends (on label 227) the 025-XX equipment code, with XX=SDI of the DMCn.
Therefore, only one DMC is addressed at a time.

The DUMP BITE MEMORY function displays a menu which presents the following failure items:
For the INTERNAL FAULT IN FLT and EXTERNAL FAULT IN FLT menus, the first two lines give a foreword, and the following lines correspond to numbered events with detailed information on the successive failures
For the FAULT ON GND menu, there is no foreword (not necessary). Note that the EIS internal faults which could occur on the ground are recorded in the zone 3 of the BITE memory, and are not transmitted automatically in plain english language to the CFDIU. The only access to this zone is by memory dump
A failure counter is associated with each failure. This counter is incremented at each failure occurrence. it is reset by means of the line key adjacent to the FAILURE COUNTER RESET indication.

C. Operational Tests at the Crew's Disposal
Several tests are offered through the MCDU menus.
Several tests are offered through the MCDU menus.
(1) Test of the engine red lines exceedances
The DMC connected to the upper ECAM DU monitors primary parameter indications of both engines.
The maximum values (red lines) of the N1, N2 AND EGT parameters are written in the BITE according to the type of engine installed on the aircraft.
Should an exceedance occur, the DMC memorizes in its BITE memory the maximum value reached during the last flight leg
The ENGINES function (4L) is used to select the ENGINES OVER SPD/TEMP page. On this page several indications give access to the limit values for each engine parameter and the exceedances if these have occurred during the last flight leg.
On this page the GENERAL RESET function (4L) serves to reset the exceedance values. This reset is automatically performed at each engine start.

(2) EIS confidence checks
The TEST function (4R) on the EIS menu displays the EIS TEST page which present three different tests.
The TEST function (4R) on the EIS menu displays the EIS TEST page which present three different tests.
- System Test Operation
The SYSTEM TEST performs all the DMC self-tests and checks the computer operation. when the line key adjacent to the SYSTEM TEST indication is pushed, a SYSTEM TEST/PROCEDURE page comes into view and shows indications for test preparation.
The RETURN function (6L) is used to select a second page which enables the test to be initiated through the line key adjacent to the START TEST indication (5L).
When the test is initiated, the DMC leaves the maintenance mode and records, in the BITE, any occurring failure until the EIS TEST page is selected in order to activate the SYSTEM TEST RESULT function (4L).This action displays the SYSTEM TEST RESULT page to show the results of the test or the TEST OK indication.
- Input test operation
During 5 s, the DMC scans all its ONSIDE buses, i.e. it checks that each bus sends labels with their correct refresh rate.
During the next 5 s, the DMC scans all its OFFSIDE buses.
At the end of this test, the DMC signals all the buses seen as faulty for display on the I/P TEST RESULTS display.
- Display Test
When a Display test is selected for a given DMC, the 3 DUs connected to this DMC display a test pattern showing the fundamental colors and geometrical outlines (lines, circles...).
