The S2I Converter reads in the selected SIMMOD scenarios and converts them into equivalent INM data. This application can be run both as a GUI application and on the command line. Data that Gets Converted: The S2I Converter reads in SIMMOD aircraft operational data and SIMMOD runway data from the history file (history.bin) and from the SIMU40 file. The aircraft data is written to the INM opt_flt file. The track data is written to the INM track and trk_seg files. Should the user wish it, the runway data is written to the runway and rwy_end files. The runway identifiers must be valid in INM regardless of whether INM runway data is converted as this information is necessary for aircraft conversion. Conversion Setting: All of the information required to convert the SIMMOD scenario(s) into an INM study is organized into conversion settings. Within each conversion setting is the included SIMMOD scenarios; conversion-specific user options; and runway identifier mappings. The SIMMOD to INM aircraft mapping data is stored separately. Status Logs: Whenever an error occurs it is logged into an error log as well as diplayed on the screen. The SIMMOD to INM conversion start and completion messages are also logged. These logs are located in the directory or folder listed in the status log location text box on the INM Settings Tab. When a conversion setting is selected, S2I writes logs to a file with the same name as the conversion setting. e.g. for a conversion setting named SAN2002, the log is SAN2002.log. Errors occurring when no conversion setting is set are written to AN_UNKNOWN_CONVERSION.log.
