AIRCRAFT INTEGRATED DATA SYSTEM
The main functions of the Aircraft Integrated Data System (AIDS) are to monitor engine condition, APU condition and A/C performance, and to provide trouble shooting assistance.
The Data Management Unit (DMU) is the heart of the AIDS. It fulfils the following functions:
- collection, processing and recording of various A/C parameters, including the mandatory parameters given by the FDIU. The recording is made in an internal memory of the DMU and on an optional external recorder called Digital AIDS Recorder (DAR),
- generate various reports according to defined conditions. These reports are stored in a non-volatile memory of the DMU.
A data loader is used to upload programmed data into the DMU and to
download recorded DMU data on a floppy disk for on ground analysis.
The printer is used to print reports generated by the DMU.
The printer can be automatically controlled by the DMU, manually controlled from the MCDU or using the AIDS PRINT P/B on the center pedestal.
The DMU and the FDIU are integrated in a single computer called FDIMU.
The FDMIU has a PCMCIA card slot to upload DMU software and download DMU data. In the A/C, two MCDUs are connected to the DMU.
To initiate communication with the AIDS via either MCDU, the user has to press the AIDS line select key from the MCDU MENU page. The AIDS MCDU menu page is then displayed.
Some of the AIDS functions, including real time parameter read out, may
be controlled from this menu.
