At this prompt, insert the first floppy disc from the SBAS Approach Database set (#1). The DLU will
recognize it then display "REINSERT DISK" and automatically search for a "Configuration file" and for
the data files to upload. Using the "Configuration File", the DLU will configure itself then it will
interrogate the GLSSU and start the data upload automatically.
If multiple data files must be loaded, the DLU will automatically sequence to the next file(s).
If the data files span multiple disks, the DLU will display the message "INSERT DISK # X" where X is
the number of the disk in the sequence. Insert this disk; if the wrong disk is inserted, the DLU will
continue to display the message "INSERT DISK # X" until the correct disk is inserted.
The transfer of data may be stopped manually by pressing the ABORT pushbutton on the DLU. The
corrupted database copy will be flagged automatically as being absent in order to prevent misuse.
Once the DLU indicates successful data transfer completion, power it off and disconnect it from the
data loader bus.
CAUTION: After data uploading, remove the ground previously applied on the Data Loader Input
Discrete line of the GLSSU, at pin 12 of the main aircraft connector J1, using for
example a switch or a jumper plug installed in the aircraft for this purpose. This action
disables the data loading process and prevents possible interference.
CAUTION: After data uploading, power-up the equipments connected on the GLSSU Data Loader
input bus, which were powered-down prior to the data loading process.
If the data transfer cannot be completed successfully, the database copy that was overwritten is not
usable since likely corrupted or destroyed. The GLSSU will flag it as "absent". However, the other
database cycle was not modified and might be usable.
Last, check the validity and status of the two database copies using the Controller Unit, typically an
FMS. Refer to the applicable operation manual in order to confirm that the update was made correctly.
