A319/A320/A321 Centralized Fault Display System (CFDS)
General
Line maintenance of the electronic systems is based on the
used of a Centralized Fault Display System (CFDS).
The purpose of the CFDS is to give maintenance
technicians a central maintenance aid to intervene at
system or subsystem level from multipurpose CDUs located
in the cockpit :
- to read the maintenance information
- to initiate various tests.
Two levels of maintenance should be possible using the
CFDS :
- maintenance at an out-station (LRU change)
- maintenance in the hangar or at the main base
(troubleshooting).

Advantages of the CFDS
A revised maintenance concept provides a :
- reduction of the duration of operations
- reduction of the maintenance crew training time
- simplification of technical documentation
- standardization of the equipment
- simplification of the computers which no longer
display any BITE ;
Integration of the CFDS
Integrated in the Maintenance and Recording Data
System (MRDS) comprising :
Basic equipment
- A Centralized Fault Display Interface Unit (CFDIU)
- A digital Flight Data Recorder (DFDR) and its
interface unit
- Two multipurpose CDUs (MCDUS) located on the
pedestal.
Note : The MCDUS can be used for : FMS, MRDS
options (ACARS, AIDS).
Optional equipment
- A multi-use printer
- A quick access recorder (QAR)
- An AIDS
