Did you ever forget to preset runways in use for an airport and be surprised by a traffic flying there? The default EuroScope's dialog is no help there with a million of checkboxes right next to each other.

This tool checks VATSIM METARs and preselects the runways for you.

Caution: The tool has to be launched before loading the sector file in EuroScope.

The configuration file is located in arse.json. Edit it to your needs.

rwy_file must point to the location of the .rwy file (corresponding to your sector file). The following are optional configuration options:

• no_factor_wind - wind, below which the wind direction is ignored for runway assigment
• pref_wind - wind, below which the wind direction is ignored when preferred runway list is used
• assumed_wind_dir - wind direction that is assumed when it is unknown

airports is a list of all processed airports. It has the following required properties:

• icao - the ICAO code
• runways - a list of runways of the airport

The following optional properties can be set:

• use_metar_from - ICAO of an airport to get the METAR from. Useful for airports that do not have METARS available on VATSIM.
• preferred_dep - an ordered list of preferred departure runway ids,
• preferred_arr - an ordered list of preferred arrival runway ids,
• no_factor_wind - overrides no_factor_wind for given airport.

A runway consists of following properties:

• id - a string identifying a runway, must be the same as the runway ID in sector file (e.g. "07L")
• true_heading - true heading of the runway, used to calculate wind angular difference
