R  The AIDS is organized around the DMU which interfaces with other aircraft 
R  systems (see AIDS - System Block Diagram). Approximately 13000 parameters 
R  from the 50 ARINC 429 data lines are fed into the DMU. 
R  Based on these parameters, the DMU performs several tasks, the result of 
R  which are either found on the SAR, on PDL floppy disks, on the 
R  PCMCIA-Card, on the MCDU screen or if they are downloaded through ACARS 
R  directly at the GSE computer in the airline ground station. 
R  The Smart Access Recorder (SAR) shall be retrieve via the PDL or 
R  downloaded on the PCMCIA-Card.

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