Narrative:

TCAS RA within class B airspace. During approach in cavu weather this morning to sfo we saw our traffic - another air carrier - on approach to runway 28L. We were on FMS bridge to 28R behind a 767. We used approach guidance up to F101D and then hand flew from that point to touchdown. Traffic was clearly in sight above and in front of us. Traffic descended below our altitude for the parallel and the symbol turned amber (traffic-traffic aural) we responded by increasing our angle of separation and slowing to our final approach speed and configuration. The system then commanded an RA climb-climb and the commanded 'clear of conflict' I must emphasize - weather conditions were visual. There was no imminent danger and there was adequate visual reference and more than adequate separation. The TCAS system did what it was supposed to do - it provided a predictive warning based on 'no action taken' to separate airplanes. We did not follow the RA blindly; we knew with certainty which airplane set it off and we appropriately adjusted our flight path to correct the warning. Both crewmembers were well rested and both were able to observe the corrective action and its results. The subsequent landing was normal with an idle reverse thrust rollout and minimum braking action and turnoff at taxiway T. ATC made no mention of any conflict and taxi in was normal.

Original NASA ASRS Text

Title: An air carrier crew reported a TCAS RA warning on short final to SFO Runway 28R behind a B767 on final for Runway 28L. The crew adjusted the profile slightly to increase clearance with the traffic in sight; and feeling in control continued the approach normally.

Narrative: TCAS RA within Class B airspace. During approach in CAVU weather this morning to SFO we saw our traffic - another air carrier - on approach to Runway 28L. We were on FMS Bridge to 28R behind a 767. We used approach guidance up to F101D and then hand flew from that point to touchdown. Traffic was clearly in sight above and in front of us. Traffic descended below our altitude for the parallel and the symbol turned amber (TRAFFIC-TRAFFIC aural) we responded by increasing our angle of separation and slowing to our final approach speed and configuration. The system then commanded an RA CLIMB-CLIMB and the commanded 'Clear of conflict' I must emphasize - weather conditions were visual. There was no imminent danger and there was adequate visual reference and more than adequate separation.
