and interrogate BITE and to initiate system tests.
Both MCDUs (Multipurpose Control and Display Unit) are
connected to the CFDS.
You can only use the CFDS on one MCDU at a time.
PRINTER
The PRINTER is used for printing information
automatically or on request.
MDDU
The Multipurpose Disk Drive Unit(MDDU) is used to load
the filter data base in the CFDIU.

CFDS: FAULT PROCESSING
BITE
Most aircraft system computers are equipped with a
Built-In Test Equipment (BITE).
The BITE monitors permanently the system operation.
When a failure is detected, it is stored in the BITE
memory and is transmitted to the Centralized Fault
Display Interface Unit (CFDIU).
Memorization of the 64 previous legs report is done
by most of the BITEs.
MEMORIZATION
Memorization of failures is different when the aircraft
is on ground or in flight.
The full BITE functions and memorization operate in
flight.
On ground, the memorization is done only in the BITEs.
The BITEs are provided with flight and ground memory
zones.
CFDIU
The CFDIU centralizes all information concerning
aircraft system failures.
Reading or printing of all the failure information is
done in the cockpit.
The CFDS (CFDIU + BITEs) functions are accessed through
the Multipurpose Control and Display Units (MCDUs).
NORMAL MODE-MENU MODE
Two CFDS modes are available. The NORMAL MODE is always
active except on ground when the MENU MODE is selected.
NORMAL MODE
In this mode, the CFDIU scans all the connected system
outputs and memorizes the failure messages in order
to generate the CURRENT (LAST) LEG REPORT and the
CURRENT (LAST) LEG ECAM REPORT.
In flight the CFDS always operates in the normal mode.
MENU MODE
In this mode, the CFDIU dialogues with one computer
at a time in order to read the contents of its BITE
memory and to initiate various tests.
This mode can only be selected on ground and interrupts
the normal mode of operation.

LAST/CURRENT LEG REPORT
A CURRENT LEG REPORT is elaborated during the flight.
After the flight, its title becomes LAST LEG REPORT.
The purpose of this item is to present the failure
messages, concerning all systems, occured during the
last/current flight.
Each message contains the test of the failure, the ATA
reference and the flight phase and time at which the
failure occured.
A function correlates the "source" failure message
with the "resulting" failure messages.
SOURCE: Name of system affected by a failure.
IDENTIFIER: Name of system affected by an external
failure which is correlated with the "SOURCE" failure.
