APCHING THE INTERSECTION OF TWO INTERSECTING RWYS; A PLT IS OFFERED AN INTERSECTION TAKEOFF. HE ACCEPTS AND THEN TAKES OFF ON THE WRONG RWY.

Narrative

TWR OFFERED INTERSECTING RWY DEP ON RWY 36 AT TXWY C; DUE TO ACFT AT OUTER MARKER FOR RWY 32L. TWR INSTRUCTED ME TO MAKE A HARD R AND CLRED FOR DEP ON RWY 36. I HAD MY ARPT DIAGRAM NEXT TO ME AND HAD BEEN CONSULTING IT. SINCE I WAS TURNING FOR THE RWY AND DEPARTING AT THE SAME TIME I WAS UNABLE TO IMMEDIATELY VERIFY RWY HEADING WITH MY DIRECTIONAL GYRO. TWR ADVISED ME THAT I WAS ON THE WRONG RWY AND STATED 'I NEED YOU OFF THAT RWY.' I ABORTED MY TAKEOFF AND DEPARTED RWY 32L AT TXWY W. THE ACFT ON FINAL ASKED THE TWR WHAT HE WANTED THEM TO DO AND THE TWR ADVISED THE ACFT TO GAR AND GET RESEQUENCED. ADDITIONAL FACTORS WERE THAT THERE WAS AN ACFT ON TXWY F BETWEEN RWYS 32L AND 36 AND I HAD ONLY BEEN TO THIS ARPT ONE OTHER TIME. THERE ARE NUMEROUS CONSTRUCTIONS IN PROGRESS AT THE ARPT. I WAS NOT PRESSED FOR TIME AND SHOULD NOT HAVE ACCEPTED THE TWR'S OFFER FOR THE AMENDED DEP. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR INDICATED IN THE CALLBACK THAT HE NOW SEES THE MERIT IN STICKING TO THE ORIGINAL PLAN INSTEAD OF ALLOWING HIMSELF TO BE SUCKED INTO THE NEVER ENDING EFFORT TO KEEP TFC MOVING AT SOMEONE ELSE'S PACE.
