Procedure; Human Factors
On final approach; cleared for a visual to Runway 06 via radar vectors; Number 1 to land. While tracking the RNAV 6 WAAS approach; a C17 was cleared for a low approach down to 1600 ft from my right tracking runway 35. Winds were out of the southeast at 11 knots; from 090-120 at my altitude; aka my 3-4 o'clock; which was where the C17 was now located. I was cleared to land prior to the C17 being approved for the low approach and descent to 1600 feet. I had been sequenced downwind; more than 10 miles from the field. Due to light chop in the descent encountered at 5000 ft and below; I slowed to 90 knots IAS on final. The C17 from the right looked as though it would overtake the intersection of 06/35 prior to my arrival. Thus; their wake descending behind them from 1600 feet to the ground; and blowing towards me at angle from their machine to the ground. I broke right and ascended into the wind towards the beach. The most dangerous flight condition I have ever encountered. Surely a student pilot may have followed this clearance and crashed.
DA40 pilot reported executing an evasive maneuver to avoid wake turbulence from a C17 landing on an adjacent runway.
