UAL93 FDR Decoder Change Log

Version
Changes
1.0
First version.
1.1
Added option to split output file in to files containing no more than 30000 rows.
The version number is now displayed.
1.2
Added option to output a maximum of one line per subframe.
Changed references to fields to refer to parameters.
1.3
Fixed problem where commas were output instead of decimal points in some regions. This would then cause confusion between commas used as decimal separators and commas used as field delimiters.


Added the following parameters:

Raw PRES POSN LAT-LSData
Raw PRES POSN LAT-MSData
Raw PRES POSN LONG-LSData
Raw PRES POSN LONG-MSData
1.4
