FLC OF AN MLG EXPERIENCED A BRIEF TCASII RA INDICATING TFC CLBING OUT TOWARD WHICH THE RPTR WAS DSNDING AND TURNING ONTO FINAL. THE TFC HAD BEEN GIVEN TO THEM AS AN ADVISORY FROM ATC WHO ADVISED NOT TO TURN BASE LEG UNTIL THE TFC WAS IN SIGHT. IT WAS AND THEY GOT THE TCASII RA.

Narrative

I FEEL THAT NO CONFLICT OR ERROR IN OP OCCURRED. I WISH TO MAKE THIS RPT; HOWEVER; BOTH TO DOCUMENT TCASII EFFECTIVENESS AND ON THE CHANCE OTHERS MAY HAVE VIEWED IT DIFFERENTLY. WE WERE ON A HIGH L DOWNWIND FOR RWY 16R. WE WERE CLRED FOR A VISUAL APCH. SHORTLY AFTERWARD WE WERE ADVISED OF VFR TFC AND TOLD NOT TO TURN BASE UNTIL WE HAD THAT TFC IN SIGHT. THAT TFC WAS ALREADY N OF THE ARPT AND FLYING NW -- AWAY FROM THE FIELD. WE SIGHTED THE ACFT. I SAW THE ACFT WHICH WAS BELOW US AND HDG THE OPPOSITE DIRECTION OF WHAT MY HDG ON FINAL WOULD BE. HE WAS ALSO W OF THE FINAL. I BEGAN A CONSTANT 30 DEG L TURN IN A DSCNT THAT I FELT WOULD KEEP ME ABOVE AND BEHIND THE ACFT. AT THE POINT WHERE MY TURNING CAME CLOSEST TO THE OTHER ACFT; I RECEIVED A VERY BRIEF TCASII RA TO 'CLB;' FOLLOWED IMMEDIATELY BY A 'CLR OF CONFLICT.' I FEEL THE TCASII GAVE THIS WARNING SINCE; HAD I REMAINED ON THE HDG THAT WOULD HAVE CAUSED A CONFLICT RATHER THAN TURNING THROUGH IT AS I DID; THERE WOULD HAVE BEEN A CONFLICT. NONETHELESS; I WAS SOMEWHAT CONCERNED TO GET THE RA EVEN THOUGH I; MY FO; AND THE OTHER ACFT ALL SAW EACH OTHER. MY FO AND I AGREED THE TURN WOULD PRODUCE DIVERGING COURSES -- US TURNING ON FINAL FOR RWY 16; AND THE OTHER ACFT CONTINUING NW. AGAIN; I FELT COMFORTABLE AND SAFE WITH THIS TURN TO FINAL DUE TO OUR VISUAL ON THE ACFT. THE TCASII WORKED AS ADVERTISED EVEN THOUGH AT NO TIME WAS THERE ANY THREAT OF CONFLICT OR NEED TO TAKE EVASIVE ACTION. ENCLOSED IS A SKETCH OF FLT.
