Most of these reports allow a change in the trigger limits or in the length of the report. In addition user specific trigger conditions can be created for each report by the use of the GSE based reconfiguration software. In addition to the above listed standard reports additional complete new reports can be programmed by the airline user.
The DMU is able to record AIDS data either by the use of the DAR or the integrated SAR. The storage medium of the DAR is a magnetic tape cartridge or an optical disk while the SAR stores the data in an Solid State Mass Memory. To read out the SAR data, use a floppy disk via the PDL.
The DMU provides various communication interface for operator dialogue and ground communications. The usage of these communication channels is mostly programmable. For example, reports can be either printed out, transmitted to the ground via ACARS or retrieved by the use of a floppy disk via the MDDU. That means each airline user can setup the DMU to support most efficiently the airline specific data link structure.
(4) DMU file transfer interfaces:
(a) MCDU
-Manual request of reports and SAR/DAR recording
-Display of list of stored reports and SAR files
-Online display of selected aircraft parameters
-Various control and reprogramming menus

(b) PRINTER - Manually initiated (by MCDU) print out of reports - Automatical print out of reports - Print out of MCDU screens - Print out of software load messages
(c) PDL - Manually initiated (by MCDU) retrieval of reports and SAR files - Automatical retrieval of reports and SAR files - Load of DMU software
(d) ACARS - Manually initiated (by MCDU) download of reports - Automatical download of reports - Upload of request for report generation - Upload of reprogramming messages
(e) DAR (optional) - Manually initiated (by MCDU) recording of AIDS data - Automatical recording of AIDS data
(f) GSE For the individual programming of the DMU functions, the DMU is reprogrammable either with the assistance of the A320 AIDS Ground Support Equipment (GSE) or partially through the MCDU's (very limited).
(g) SAR The data from the SAR data storage buffer are retrievable through the MDDU. To initiate manually some specific reports a remote print button 3TV is located on the pedestal in the cockpit. Also SAR recording is triggered through the print button. The report/SAR channel assignment of the remote print button is GSE programmable.

R R R R R R R (Ref. Fig. 002) The AIDS mainly consists of the Data Management Unit (DMU) and an optional Digital AIDS Recorder (DAR). The DMU is the central part of the AIDS and is reconfigurable via the Ground Support Equipment (GSE). The DMU is a high-performance avionic computer specialized for the acquisition of ARINC 429 DITS data and associated processing.

R The multi tasking architecture allows processing of the various
R tasks in real time.
R An integral part of the DMU is the optional Smart Access Recorder
R (SAR). This function is based on a nonvolatile Solid State Mass
R Memory (SSMM) module which is used to store flight data.
R Sophisticated data compression algorithms ensure efficient usage

R A further integral part of the DMU is the PCMCIA interface. This
R interface is able to accept rotate and solid state ATA disks to
R store SAR data, DAR data or generated AIDS standard reports.
