Synopsis

LGT FLC HAS TCASII RA ON APCH; MAKES GAR.

Narrative

HAD BEEN KEPT HIGH DURING A CIVET 4 APCH TO RWY 25L AT LAX; WAS ISSUED TA'S 3 OR 4 TIMES FOR ACFT LOW AND AHEAD; WAS UNABLE TO PICK OUT ANY TARGETS. I WAS FINALLY CLRED A VISUAL TO RWY 25R FROM 5000 FT AND QUITE CLOSE IN. WITH GEAR DOWN AND FLAPS 20 DEGS (AIRSPD 170 KTS) APCHING 4500 FT I RECEIVED AN RA FROM TCASII. HSI SHOWED ACFT VERY CLOSE AND ALMOST DIRECTLY BELOW. I FOLLOWED THE RA BY CLBING AND WAS THEN TOO CLOSE IN FOR APCH. INFORMED TWR WE WERE GOING AROUND AND PROCEEDED TO ARPT AT APPROX 4500 FT AND WAS CLRED TO DSND TO 2000 FT. WE RETRACTED GEAR AND FLAPS; DURING DSCNT RECEIVED A TA FOLLOWED BY ANOTHER RA. WAS ABLE TO VISUALLY SIGHT TARGET ACFT AND DID NOT HAVE TO FOLLOW THE RA. PASSED ABOVE AND BEHIND ACFT. WAS VECTORED FOR A VISUAL APCH TO RWY 24R AT LAX; APCH AND LNDG UNEVENTFUL. I CONTACTED LAX TWR (APCH CTL) AFTER LNDG; AND WAS TOLD I CREATED A LOT OF PROBS BY FOLLOWING RA AND GOING AROUND. I REPLIED THAT COMPANY (AND MY) POLICY IS TO FOLLOW ANY RA FOR A TARGET THAT CANNOT BE VISUALLY IDENTED. CTLR SEEMED TO BE HAVING DIFFICULTY WITH MY POS (POLICY). COMPANY ALSO HAS POLICY THAT STATES YOU CAN TURN OFF RA AND ONLY USE TA POS ON TCASII IF YOU ARE IN A HIGH TFC AREA (LIKE LAX) USING PARALLEL APCHS. HOWEVER; THIS IS UP TO THE CAPT'S DISCRETION. WHICH MEANS YOU ARE DAMNED IF YOU DO AND DAMNED IF YOU DON'T. REGARDLESS OF ATC PROBS; I WILL CONTINUE TO FOLLOW ANY RA THAT I CANNOT VISUALLY IDENT. AN ATC PROB IS PREFERABLE TO BROKEN ACFT AND DEAD PEOPLE (PAX).
