Wind farms: A danger to ultra-light aircraft?

Airfields for ultra-light aircraft are typically constructed on level ground – and so are wind farms. However, do wind power plantsgenerate turbulence that could endanger lightweight planes? A simulation can compute how these power plants influence aircraft at various wind speeds and wind directions.
