HOW TO RECORD IN-FLIGHT PARAMETERS

When reports (06), (07), (09), (14), (15) or (19) are automatically triggered, maintenance and investigative actions are required.
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 using the Ground Support Equipment tool (see below).
The reports are described in the relevant Aircraft Maintenance Manual, section 31-36-00 or in the Technical Description Note provided at the aircraft delivery by the DMU/FDIMU system manufacturer.
4.3.3.2. DMU/FDIMU transfer file interfaces
The DMU/FDIMU provides various communication interfaces for operator dialogue and ground communications. The usage of these communication channels is mostly programmable. For instance, reports can be printed out or, transmitted to the ground via ACARS or retrieved on a floppy disk via the airborne data loader (MDDU). This means that each operator can set up the DMU/FDIMU to most efficiently support the airline specific data link structure. The picture below shows different data flows from the aircraft to ground operations. All interfaces are then described one by one.
