RECORDING SYSTEM COMPONENT LOCATION (2)
SYSTEM OVERVIEW
The Flight Data Interface and Management Unit (FDIMU) has two primary functions. The first is the Flight Data Interface Unit (FDIU) function.
To obey the mandatory requirements of crash recording, the FDIU acquires and formats several important flight parameters and system data before it supplies them to the Solid State Flight Data Recorder (SSFDR). The linear accelerometer measures the acceleration of the A/C in all three axes. The System Data Acquisition Concentrator (SDAC) digitizes the analog signal of the linear accelerometer and sends it to the FDIU.
For maintenance and performance purposes, the optional Quick Access Recorder (QAR) records the same parameters as the SSFDR. The operation of the SSFDR is automatic.
On the overhead panel, there is a GrouND ConTroL P/B, which is on the ReCorDeR panel. This P/B lets the SSFDR be supplied when the A/C is on ground for preflight checks before engine start or for tests and maintenance. On the center pedestal, there is a Digital Flight Data Recorder (DFDR) EVENT P/B, which can be used to set an event mark on the SSFDR memory.
UP & DOWN DATA LOADING SYSTEM PRESENTATION (2)
GENERAL
The data loading system is an interface between the aircraft computers and ground data processing equipment used to update software (S/W) and database or to retrieve aircraft system data. The data loading system includes:
- a Data Loading Selector (DLS) to select the computer on which data will be loaded,
- a Multipurpose Disk Drive Unit (MDDU) to upload or download data,
- a stowage box with a 42 disk maximum capacity (the Disk Stowage is in the left and right sides consoles and can be locked with a key),
- a Data Loading Routing Box (DLRB) to route the input/output data between the disk unit and the target computer.
When Portable Data Loader (PDL) connectors are installed, ARINC 615A data loading of the Air Traffic Service Unit (ATSU) and Air Data Inertial Reference Units (ADIRUs) is possible.
UP LOADING
The aircraft system computers use the loading system to update their data base, for example the Flight Management and Guidance Computer (FMGC) or to modify parts of their operational S/W, for example the ATSU. The Up loading is automatically done from a 3.5 inch disk, via an internal logic specific to each computer.
Power supply plug is installed to enable data loader power supply.
DOWN LOADING
The down loading system is used to down load, to a 3.5 inch disk, the data recorded by some computers during aircraft operation, for example the Data Management Unit (DMU) part of the Flight Data Interface and Management Unit (FDIMU). Down loading is done automatically through an internal logic specific to each computer.
