Narrative:

Flight landing FMS visual runway 28R at sfo. Time was XA55Z and at 1200-1000 ft AGL I made right s-turns to give more lateral distance to a crj on a visual approach to sfo runway 28L. While still on bay approach frequency, outside 'the bridge,' ATC gave us 'traffic,' and told us bout the rj on our left rear. ATC earlier had given us a speed of 170 KTS, then just before the bridge, gave us '160 KTS rj will follow you, contact tower.' soon thereafter, we got a TCASII TA for the rj. I looked back and saw he was much faster than us. To avoid an RA, I switched the transponder to 'TA' and made a turn to the right to avoid being too close. The rj flew right on and passed us on our left. We notified tower we were s-turning because they were passing us and it was too close. I determined it was safe to continue and did so, making an uneventful landing. After landing, I queried sfo tower about the situation and they did not seem to be interested or concerned. I am not sure of the distance between my aircraft and the rj at that time but in my mind it was too close, and I believe it would have been a TCASII RA or a go around had I not taken action. I believe it was poor judgement and lack of experience on the rj's part and lack of action and apathy on ATC's part. Possibly due to the nice clear WX.

Title: A320 CREW ON A SIMULTANEOUS VISUAL APCH INTO SFO FELT TFC ON THE PARALLEL RWY WAS TOO CLOSE.

Narrative: FLT LNDG FMS VISUAL RWY 28R AT SFO. TIME WAS XA55Z AND AT 1200-1000 FT AGL I MADE R S-TURNS TO GIVE MORE LATERAL DISTANCE TO A CRJ ON A VISUAL APCH TO SFO RWY 28L. WHILE STILL ON BAY APCH FREQ, OUTSIDE 'THE BRIDGE,' ATC GAVE US 'TFC,' AND TOLD US BOUT THE RJ ON OUR L REAR. ATC EARLIER HAD GIVEN US A SPD OF 170 KTS, THEN JUST BEFORE THE BRIDGE, GAVE US '160 KTS RJ WILL FOLLOW YOU, CONTACT TWR.' SOON THEREAFTER, WE GOT A TCASII TA FOR THE RJ. I LOOKED BACK AND SAW HE WAS MUCH FASTER THAN US. TO AVOID AN RA, I SWITCHED THE XPONDER TO 'TA' AND MADE A TURN TO THE R TO AVOID BEING TOO CLOSE. THE RJ FLEW RIGHT ON AND PASSED US ON OUR L. WE NOTIFIED TWR WE WERE S-TURNING BECAUSE THEY WERE PASSING US AND IT WAS TOO CLOSE. I DETERMINED IT WAS SAFE TO CONTINUE AND DID SO, MAKING AN UNEVENTFUL LNDG. AFTER LNDG, I QUERIED SFO TWR ABOUT THE SIT AND THEY DID NOT SEEM TO BE INTERESTED OR CONCERNED. I AM NOT SURE OF THE DISTANCE BTWN MY ACFT AND THE RJ AT THAT TIME BUT IN MY MIND IT WAS TOO CLOSE, AND I BELIEVE IT WOULD HAVE BEEN A TCASII RA OR A GAR HAD I NOT TAKEN ACTION. I BELIEVE IT WAS POOR JUDGEMENT AND LACK OF EXPERIENCE ON THE RJ'S PART AND LACK OF ACTION AND APATHY ON ATC'S PART. POSSIBLY DUE TO THE NICE CLR WX.
