-An optional PCMCIA card (A320 FAM aircraft only)
The integrated PCMCIA interface can store the AIDS/ACMS standard reports. To store data via the PCMCIA interface, a PCMCIA card in MS-DOS format is required. The advantage of the PCMCIA card is that the time to access the media is much lower than when using a floppy disk in the airborne data loader. The PCMCIA card can be connected to a Personal Computer to dump the data for further analysis.
-An optional ATSU (ACARS function).
For those aircraft equipped with the Aircraft Communication and Reporting System, it is possible to send the AIDS/ACMS reports directly on the ground. The format of the reports is different from the ones that can be retrieved directly from the DMU/FDIMU (see above) because every transmission costs money.
This system is essential for engine and aircraft monitoring of important fleets. It allows to transfer high quantities of data and treat these automatically.
The ACARS function / AIDS/ACMS interface provides the capability to transmit to the ground reports for the following applications: -aircraft performance monitoring : APM -engine condition monitoring : ECM -APU health monitoring : AHM
Any of the AIDS/ACMS DMU/FDIMU reports can be downloaded: -manually on ground or in flight -automatically after a particular event -after ground request
