Data Errors

The data is presented based on the metar.xml data downloaded from aviationweather.gov. There has been an uptick in late 2025 of parsing errors in that data set, that has resulted in wind direction being presented as windspeed. These errors are in the source data published by the US Government. Some additional parsing and validtion code is being written to try catch these errors.

Runway Slope (Beta)

Many airport runways are not perfectly flat along the length. Some are on the side of hills and are sloped. Some have raised sections, or depressions along the length. The large airport/runway datasets that are available often do not include specific runway elevation information. Where it is provided, it is sometimes a single elevation - which must be assumed to be the middle of the runway. Where two elevations are provided they can be interpreted as the elevations for both ends of the runway. There does not appear to be consistent application of measurements to factor in offset thresholds. Even if the data is available and accurate - there is no guarantee that the terrain mesh in the flightsim accurately represents the data.
