I’ve recently become interested in investigating wake turbulence
from wind turbines. We have several wind farms in South Australia. I wrote an
article for the SA Airspace Users Group and it was published by the (Aus) HGFA
‘Skysailor’ magazine. The article, “Wake Effects of Wind Turbines,” can be found
on page 38 of the Sept/Oct 2016 edition -

It seems that there has been very little research into this and what there has
been was aimed more at GA-type aircraft. It seems that perhaps the UK’s CAA have
gone the furthest to acknowledging that wake turbulence from wind turbines can
be a problem to very light aircraft and gliders, etc.

Admittedly, it’s very difficult to measure/quantify turbulence or to define how
much turbulence would be a problem to us. This is why actual descriptions are
required from pilots who have experienced this. I don’t want it to take a
fatality to prove a point.

I’d be interested to hear any reports from hang gliding, paragliding, or
trike/ultralight pilots who have flown/landed downwind of wind turbines and
lived to tell the tale. I think that the Oz Report Forum would be a good place
for hang gliding, paragliding, or trike pilots to make such reports, after an
initial mention in the Oz Report.
