The airfield management has never heard of the effect from other pilots, and suggested that "there can be some shadowing from the trees to the west of the clubhouse".
Studies of wind turbine turbulence estimate that the effect dissipates within the distance of 5-8 times of the rotor diameter.
The runway was 15-17 times of the rotor diameter away in this case.
