PC12 PLT RPTS ENCOUNTERING WAKE TURBULENCE SHORTLY AFTER TKOF FROM DAL AND NOT TURNING TO ASSIGNED HDG WHILE TRYING TO AVOID A SECOND ENCOUNTER.

Narrative

I RECEIVED MY CLRNC FROM DAL LOVE CLRNC. CLRED TO AUSTIN INITIAL L TURN TO 185 DEGS HDG; RADAR VECTOR ACT-V17-DIRECT; CLB AND MAINTAIN 2000 FT AND EXPECT 8000 FT. WX OBTAINED FROM ATIS: 030/10 10 120000 SCT; 27000 SCT; 10/0 30.38 VIS APCH RWY 31L & RWY 31R. I WAS CLRED BY TWR FOR TKOF ON RWY 31R AND ADVISED OF WAKE TURBULENCE BEHIND A B737. I ACCEPTED THE TAKEOFF CLRNC AND STARTED MY TAKEOFF ROLL. UPON LIFTOFF I IMMEDIATELY EXPERIENCED WAKE TURBULENCE AND OFFSET MY HDG TO 285 DEGS FOR MY CLBOUT. CLOSE TO 2000 FT I WAS SWITCHED TO DEP FREQUENCY AND ADVISED THAT I WAS 2000 FT AND GAVE MY HDG AS 285 DEGS; I WAS TOLD TO CLB TO 3000 FT AND TURN TO 140 DEGS AND 'MOVE IT ON AROUND.' I DID AS REQUESTED AND CONTINUED ON THE FLT WITHOUT FURTHER INCIDENCE. I BELIEVE MY FAILURE TO START THE CLRNC TURN IMMEDIATELY TO 185 DEGS MAY HAVE CAUSED CONCERN FOR DEP CTL. I ALSO MADE A MISTAKE IN NOT STATING THAT I WAS IN THE TURN; I RELAYED THE HDG I HAD OFFSET TO AVOID WAKE TURBULENCE. ALTHOUGH I WAS STARTING MY TURN; I RELAYED THE HDG DISPLAYED AND ALTITUDE; WHILE I TRIED TO MAINTAIN LEVEL FLT FROM THE WAKE TURBULENCE. IN MY OPINION; I NEVER DEVIATED FROM MY CLRNC; I ONLY DELAYED IN STARTING MY INITIAL TURN TO THE ASSIGNED HDG TO MAINTAIN LEVEL FLT IN THE FACE OF THE B737 WAKE TURBULENCE AND GAVE A SIMILAR HDG TO THE CLRED HDG. DEP MUST HAVE ASSUMED THAT I WAS IN ERROR AND NEVER QUESTIONED MY HDG OR REASON FOR THE HDG. I WAS INFORMED OF A PROBLEM OVER WACO; BY WACO APCH THAT I NEEDED TO CALL FORT WORTH DUE TO A POSSIBLE PLT DEV. IN THE FUTURE; IN ORDER TO AVOID CONFUSION; I MUST BE VERY CLR WHAT MY INTENTIONS ARE; AND BE VERY PRO-ACTIVE; EVEN IN HIGH STRESS SITUATIONS; TO RELAY ALL MOVEMENTS TO THE APPROPRIATE FREQUENCY AND TO STATE INTENTIONS; IE; STARTING TURN TO ASSIGNED HEADING; INSTEAD OF CALLING OUT A HDG I HAPPENED TO BE ON FOR OFFSET.
