How are airport SOPs implemented in BeyondATC

Airport standard operating procedures are used in BeyondATC to assign runways based on factors such as wind conditions and airport preferences. Here’s an example of how airport data is defined for KLAX (Los Angeles):

{
  "icao": "KLAX",
  "low_wind_speed": 5,
  "low_wind_runways": ["24L", "24R", "25L", "25R"],
  "primary_departing_runways": ["25R", "24L", "07L", "06R"],
  "primary_arrival_runways": ["25L", "24R", "06L", "07R"],
  "frequencies": [
    {
      "runway": ["24L", "24R", "06R", "06L"],
      "tower": {
        "name": "Los Angeles",
        "frequency": 133.9
      },
      "ground": {
        "name": "Los Angeles",
        "frequency": 121.65
      },
      "departure": {
        "name": "SOCAL",
        "frequency": 125.2
      },
      "approach": {
        "name": "SOCAL Approach",
        "frequency": 124.5
      }
    },
    {
      "runway": ["25L", "25R", "07L", "07R"],
      "tower": {
        "name": "Los Angeles",
        "frequency": 119.8
      },
      "ground": {
        "name": "Los Angeles",
        "frequency": 121.75
      },
      "departure": {
        "name": "SOCAL",
        "frequency": 124.3
      },
      "approach": {
        "name": "SOCAL",
        "frequency": 124.9
      }
    }
  ]
}

Setting	Description
Low wind speed	The wind speed threshold (in knots) for the preferential runway system. When the wind speed is below this threshold, specific low-wind runways are used.
Low wind runways	Runways used in calm wind conditions (when wind speed is below the defined low wind threshold) and during tailwind situations. These are the preferred runways in low-wind or tailwind scenarios.
Primary departing runways	Runways designated for departures.
Primary arrival runways	Runways designated for arrivals.
Frequencies	This section groups communication frequencies based on the runway groups to separate communication between multiple frequencies in bigger airports.

If wind speeds are below the specified threshold (low_wind_speed), the system will choose runways from the list of low_wind_runways for both arrivals and departures, unless there is a stronger tailwind.

Currently, the airport SOPs implemented in BeyondATC are relatively simple in design, focusing primarily on essential factors such as wind conditions and runway assignments. However, there are plans to enhance and expand these procedures in the future to incorporate more complex decision-making processes and better simulate real-world operations.
