Narrative:

Descending through 10000 ft to 9000 ft, a heading of 130 degrees from approximately 90 degrees was given, then a 150 degree heading, then a 180 degree heading at which time the aircraft TCASII RA sounded commanding a climb. As climb was initiated the conflict was resolved and descent to 9000 ft was completed. I feel a turn to the left would have avoided the conflict and we would have passed behind and then turned right to follow the aircraft in question.

Title: RECEIVED TCASII RA WHILE ON TRACON VECTORS.

Narrative: DSNDING THROUGH 10000 FT TO 9000 FT, A HDG OF 130 DEGS FROM APPROX 90 DEGS WAS GIVEN, THEN A 150 DEG HDG, THEN A 180 DEG HDG AT WHICH TIME THE ACFT TCASII RA SOUNDED COMMANDING A CLB. AS CLB WAS INITIATED THE CONFLICT WAS RESOLVED AND DSCNT TO 9000 FT WAS COMPLETED. I FEEL A TURN TO THE L WOULD HAVE AVOIDED THE CONFLICT AND WE WOULD HAVE PASSED BEHIND AND THEN TURNED R TO FOLLOW THE ACFT IN QUESTION.
