AN A320 CAPT RPTED THAT HE WENT THROUGH FINAL AT LAX; CAUSING AN RA; AFTER A SERIES OF PROBS.

Narrative

ON RIGHT BASE TO RWY 24R AT LAX; APCH CTRL ASKED US TO RPT 2 PLANES IN SIGHT. I HAD 1; BUT NOT BOTH; RESPONDED TO FO BUT HE DID NOT HEAR CORRECTLY. WE WERE THEN CLRED FOR VISUAL APCH TO RWY 24R. CRM BREAKDOWN. APCH GAVE US A LATE CLRNC; AND WE HAD TO CORRECT NOT HAVING BOTH PLANES IN SIGHT. WE WENT THROUGH FINAL AND HAD AN RA. I TURNED THE AUTO-THROTTLES OFF AND HIT TOGA; TO FOLLOW CLB RA AND CONTINUED TURING TO AVOID 1 PLANE. WE WERE UNABLE TO SELECT APCH AIRSPD EVEN AFTER RE-SELECTING APCH MODE. THE SPD BUG REMAINED AT ABOUT 180KTS. MANUAL THROTTLES WERE USED TO CONTINUE THE APCH AT THE CORRECT V APCH SPD; BUT HIGHER. NORMAL LNDG AND ROLLOUT. CRM; ATC; AND ACFT SYS CONTRIBUTED TO BEING VECTORED TOO CLOSE TO ANOTHER ACFT; WHILE ACFT SYS PREVENTED A 'NORMAL SOP' LNDG IN VFR CONDITIONS. WE BELIEVED THAT THE SAFEST PLAN WAS TO CONTINUE TO LAND. THE SUN WAS BLINDING AND DIM DISPLAY UNIT (PFD AND NAV) MADE SEEING ALL INSTRUMENTS HARD AS WE WERE FLYING INTO THE SETTING SUN AND HAZE. ALL FACTORS LED TO DEV OF SOP AND WE THOUGHT THAT THE LACK OF CTL OF THE FMS AUTOMATION MADE IT SAFEST TO LAND.
