I have experienced windshear many times in my flying career in the outback and northern parts of Australia. The most frightening was when I have departed Chillagoe in north Queensland in the middle of winter around midday in a Queenair with 10 pob, temp was around 30 degrees , wind 140 at 10 kts runway heading by memory 180. Elevation about 2000' There is a hill to the left of the runway just after the threshold reaching about 500 feet over runway height. I was at max TOW, got airborne at end of runway when sudden gust of wind hit me from behind caused by turbulance from hill from the left. Despite of ten degrees of flap, gear up, full power, my instruments showing positive rate of climb, I could see by glancing out of my windows that in fact I was not climbing. By miracle after passing the hill to my left I got a sudden gust that got me enough height to clear the rocks in my immediate front that filled the windscreen which I will never forget.
I have survived another day.
