1. General
A. CFDS
The CFDS is a centralized maintenance aid system which gives the maintenance technicians a means to read the maintenance information related to most of the aircraft systems and to initiate the tests of these systems from the cockpit.

B. Data Recording System
This system is a centralized system to record the parameters from most of the aircraft systems. These recordings serve to determine the causes of incidents or accidents and are also an aircraft maintenance and monitoring raid.

(1) Basic recording system
The function of this system is to record the mandatory parameters necessary for the Certification Authorities, and important basic parameters. These parameters serve in case of incident or accident.

2. System Description
A. CFDS
The CFDIU is connected to most of the electronic systems (BITE) of the aircraft and stores failure information from these systems in memory.
It also serves to initialize tests in each system.
The MCDUs are control and display units. They serve to dialogue either with the CFDIU or with a particular aircraft system (via the CFDIU) to display failure information or to initialize tests.
The printer provides print-outs of the various maintenance reports available.

B. Data Recording System
The FDIU is connected to several electronic systems of the aircraft and performs acquisition of several parameters. These parameters are transmitted to the DFDR and to the Quick Access Recorder (QAR) (if installed). This recording serves in case of incident or accident : it is included in a protected area.
The DMU is connected to other aircraft systems and performs acquisition of other parameters. These parameters are also transmitted to the Digital AIDS Recorder (DAR) (if installed).
The DMU is also connected to the MCDUs and to the printer to give direct display of certain parameters.
These parameters are used as an aid to aircraft system monitoring and maintenance (in particular engine monitoring).
The FDIMU is connected to different A/C-systems and receives data in discrete and digital format.

The FDIMU is connected to different A/C-systems and receives data in discrete and digital format.
- The FDIU-part of the FDIMU collects all critical flight-parameters from various A/C-system and sends it to the DFDR. These flight-parameters are stored to the DFDR and to the Quick Access Recorder (QAR) (if installed).
- The DMU-part of the FDIMU performs acquisition of the others parameters. These parameters are stored for internal processing and transmitted to the Digital AIDS Recorder (DAR) (if installed).
Via the MCDUs in the cockpit, it is possible to control the FDIMU and to see system-reports.
3. Operation
Utilization of the CFDIU and of the Data Recording System is based on an interactive dialogue between the system and the MCDU.
