FLIGHT DATA INTERFACE UNIT-GENERAL DESCRIPTIONGENERALThe FDIU (Flight Data Interface Unit), which is a part of the FDIMU aquires thesame parameters as the DMU.The FDIU send these data to the DFDR (Digital Flight Data Recorder). Theseparameters can also be recorded on the PCMCIA card and on a QAR, ifinstalled.

DFDRS FunctionThe FDIUpart collects all critical flightparameters from various A/Csystemsand sends it to the DFDR. The FDIUparts converts the flight parameters andsends them in serial digital format to the DFDR (ARINC717 databus). Theseflightparameters are stored to the DFDR (and to the QAR, if installed).At the same time the FDIU sends an audio signal with encodedGMTinformation to the CVR (Cockpit Voice Recorder) for synchronization.The GMT information is provided from the active CMC (Back Up Clock) if themain clock fails.The LA (Linear Accelerometr) generates acceleration data in analog format.The information from the LA is sent to the FDIU part via SDAC (System DataAcquisition Computer). The SDAC converts this information to a digital formatfor the FDIUpart which sends these acceleration data to the DFDR togetherwith the other flightparameters.The status of the DFDR and the status of the FDIU (failure/no failure) ismonitored by the SDACs. If a failure occures, it is shown on the ECAM display.For maintenance and test of the DFDRS, the FDIU is connected with the CMC(Central Maintenance Computer) of the CMS (Central Maintenance System).The testconnector enables the connection of portable testequipment and adataloader to the FDIMU.The recorder has the capability to store all data which the FDIUpart of theFDIMU has collected over the last 25 hours.

Mandatory ParameterIntegrityCheckThe FDIF (Flight Data Interface Function) performs a mandatory check forparameterintegrity during flight. The result is stored in a nonvolatile memoryin the FDIMU. The result is also recorded on the DFDR and on the QAR in therespective data words.

ACMS DESCRIPTION/OPERATIONFDIMUThe FDIMU integrates the former FDIU (DFDRS function) and DMU (ACMSfunction) with a PCMCIA interface into a single LRU. These two functionsoperate independently from each other: The FDIU part is dedicated to the Flight Data Recording System for

incident/ accident investigation. The DMU part is used to monitor aircraft systems condition, mainly engines

and APU systems, as well as aircraft performance in order to schedulemaintenance tasks, operation recommendations to be formulated, andtrouble shooting assistance.

For PCMCIA recording purposes data transmission between these two parts isprovided by an internal ARINC 429 data bus.

DMUThe DMU part is the main part of the ACMS. The main function of the DMUpart is to generate reports or/and to record raw data from aircraft system data(by ARINC 429 low- and high speed data buses) collected and continuouslymonitored by the DMU.This data is stored into buffer memories and retrieved to provide, if required,preevent data for report generation or/and raw data recording. In additionspecific trigger conditions are programmed in the DMU part set up databasethanks to a GSE. So that, when a preprogrammed trigger condition is detectedby the DMU monitoring, the DMU part software generates automaticallypreformatted ACMS reports or/and records automatically raw data surroundingthis specific event.The DMU stores these reports on its internal nonvolatile SSMM (solid statemass memory). The DMU stores the sets of raw data on an external optionalDAR or/and compresses and stores this data on its memory (SAR function).The SAR and DAR data and the reports can also be recorded on the PCMCIAmemory card, when installed. The DMU is fitted with a BITE function thatreports ACMS status to the CMS.NOTE: The ACMS function is very flexible and allows, through the GSE,

to customize or create trigger conditions, reports and sets of rawdata. Further GSE can perform a partition of the SSMM (insidethe DMU) between reports, SAR data and buffers.

REPORTSThe DMU part generates a set of 21 preprogrammed ACMS reports, functionalat Aircraft delivery, called Airbus Standard Reports. The AI standard reportsare monitorfunctions with specified trigger mechanism, specifieddatacollection and with specified outputformat.The performance of these Reports is the basic aircraftmonitoring function,which collects parameters for trend analysis of: Aircraft performance monitoring, Engine monitoring, APU monitoring.

Further applications are: Miscellaneous monitoring functions related to structure, RAT, ECS and door

monitoring, Troubleshooting and in depth investigation.

If needed, further reports called free programmable reports. The operator canchange some parameter to customize the AI standard Reports through theMCDU or GSE.All these Reports start automatically in case of the aircraft operates unusual orincorrect (e.g. engine overtemperature).A report consists of a fixed and comprehensive set of data collected underpredefined trigger logic and callup through callup codes. The ACMS reportsmay also be triggered either by a manual request via the ACMS Remote Printbutton, or via an ATSU uplink request.Finally the ACMS reports can be: printed out on the cockpit printer in flight or in ground, downloaded on ground only from the ACMS memory via the MDDU or via

the PCMCIA interface card, Downlinked through ACARS function (ATSU) in flight or on ground.

ACMS DESCRIPTION/OPERATION (CONT.)SAR FUNCTIONThe SAR (Smart ACMS Records) function provides compression and recordingof a predefined set of raw data related to particular flight events. This data setis stored in the DMU part SSMM and if programmed in the PCMCIA card aswell.The SAR recording can be triggered: Automatically when programmable triggers are met, Manually via the MCDU.

The memory of the DMU part dedicated to the SAR, is split into separatechannels (up to 8) with different sizes used to store SAR files. Each channelcan have up to 32 programmable start/stop trigger conditions runningsimultaneously and fully customized. When a trigger condition is met, a newSAR file is opened and is used to store the corresponding predefinedcompressed data. In addition, each channel can be programmed to recordpreevent data for extended trouble shooting.SAR data is not directly accessible on board. SAR data files are dumped onground only via the MDDU or via the PCMCIA interface, either automatically ormanually. Data is then graphed or tabulated using the READOUT function ofthe GSE. The only information available on board the aircraft is related to SARfile characteristics displayed on the MCDU.The Airbus Industrie standard default SAR programming has no channelsdefined or automatic triggers programmed. The user must initiate all programs.

DAR FUNCTIONThe optional DAR records the raw data sent by the DMU part on frames likethe DFDR.DAR recording activation can be: automatic by preprogrammed logical aircraft event triggers (up to 64 GSE

programmed triggers available), manual through the MCDU, continuous during the entire flight, continuous or intermittent during a specific flight phase.

The DAR memory support is then read out by a specific DAR AGS (AnalysisGround Station) and used for longterm trending and shortterm troubleshooting.The DAR recording speed can be set from 64 word/second up to 1024 word/second by GSE.The Airbus standard default DAR programming consists of a predefined 64word/secondframe format but with no automatic triggers defined.The DAR includes a BITE function, which reports the status to the DMU.The PCMCIA interface, if it is installed, can be used to store the same data asthe DAR recorder.

PCMCIA BOARD AND INTERFACE (New Menu Function: PCMCIA)The PCMCIA board provides an interface in order to: store ACMS reports as well as DAR and SAR data independently from the

recording done in the DMU and in the DAR. store DFDRS control flight parameters independently from the recording

done in the QAR (Quick Access Recorder). upload ACMS system software and ACMS setup database. download ACMS reports and raw data (SAR).

The PCMCIA board is managed by the DMU processor and is accessiblethrough an access door on the FDIMU front face.

DAR-RECORDER-DESCRIPTIONDAR ConstructiontionThe installed DAR is an extended storage Digital ACMS Recorder. The dataare stored on an onboard rewritable optical disk. The quick access to the diskand the EJECT pushbutton is through a door, which is in the front panel ofthe DAR as well as a FAIL indicator light.An Interactive Display System, located on the frontpanel, consists of one16character alphanumeric display.The disk medium is a standard of 3.5 and a large storage capacity of120 Mbytes per formatted disk.The drive and control board controls the speed and direction of the disk motion.A BITE logic monitors the reel rotation, the disk speed and presence of dataand disk. In case of discrepancies, the status output is received by the DMU.The disk must be formatted to store the data.NOTE: Change/Insertion of the Optical Disk has to be performed

according Job-Card or other corresponding instructions (AMM)

The following messages are possible: DISK DETECTED (Disk is initially inserted in the disk drive) CHANGE DISK (Problem with an optical disk, which has just been

inserted into the drive) DATA FILE FULL (The raw data file or the report data is full) EJECTING (Ejecting of the inserted optical disk is in progress) **BAD DISK (Inserted optical disk is not a valid data disk) INITIALIZING (The optical QAR is initializing) INSERT DISK (No optical disk is inserted) WRITE PROT (The optical disk is write protected) **WRONG DISK (The data disk is not compatible with the current version

of the optical QAR software) TEMP OK (The unit temperature is in range after being out of

range) TEMP TOOR (HI/LO) (The unit temperature is out of range. HI is too hot

and LO is to cold) SERV.DRIVE ADVS. (Oncondition maintenance action is required to

return the optical drive to servicable condition) **ERROR 1 (The system could not initialize) **ERROR 2 (The system could not initialize the optical drive) OPEN LEAK (The system has tried to open too many files) POWER FAIL (The system detected a power failure) FLASH REPORT (The system has detected a problem with the PCMCIA

flash memory or subsystem) **EJECT ERROR (The system has detected a problem to eject the

inserted optical disk) OQAR READY (The optical QAR is operating) LOCATE FAIL (The optical QAR is not able to open the locator file on

the data disk)
