Narrative:

ATC facility: sierra approach, sfo tower. Location: sfo 280 degree radial, 3 DME approach. I was flying the FMS bridge visual runway 28R at sfo. The visibility was good, so the approach controller gave us the visual to runway 28R with a slowdown to 190 KTS. He called traffic of a B747 coming in from the south. We saw the traffic and told the approach controller. During the approach just after 1000 ft, the B747 came up to our wingtip and passed us. His rate of speed and closure surprised us. He landed on runway 28L when we were at 200 ft. We kept above his glide path and stayed out of his wake turbulence. At touchdown the power had to stay up longer probably due to some wingtip vortices just near touchdown. In retrospect, a go around might have been considered and something said to ATC about the spacing problem between our airplanes. The sfo commercial page 13-2A does not allow for a larger airplane to pass another airplane. Supplemental information from acn 572296: location: FMS quiet bridge visual approach. I concur with captain's as soon as possible report. Although constant crew coordination was necessary during FMS arrival/approach to runway 28R, and landing due to ATC spacing of B747-400 on parallel arrival to runway 28L, arriving on our wingtip and subsequently pass us (see sfo fmii page 13-2A) we landed without incident remaining above the B747's glide path and maintaining awareness of possible wingtip vortices.

Title: A B757 ON AN FMS APCH TO SFO RWY 28R IS PASSED ON FINAL BY A B747 LNDG RWY 28L.

Narrative: ATC FACILITY: SIERRA APCH, SFO TWR. LOCATION: SFO 280 DEG RADIAL, 3 DME APCH. I WAS FLYING THE FMS BRIDGE VISUAL RWY 28R AT SFO. THE VISIBILITY WAS GOOD, SO THE APCH CTLR GAVE US THE VISUAL TO RWY 28R WITH A SLOWDOWN TO 190 KTS. HE CALLED TFC OF A B747 COMING IN FROM THE S. WE SAW THE TFC AND TOLD THE APCH CTLR. DURING THE APCH JUST AFTER 1000 FT, THE B747 CAME UP TO OUR WINGTIP AND PASSED US. HIS RATE OF SPD AND CLOSURE SURPRISED US. HE LANDED ON RWY 28L WHEN WE WERE AT 200 FT. WE KEPT ABOVE HIS GLIDE PATH AND STAYED OUT OF HIS WAKE TURB. AT TOUCHDOWN THE PWR HAD TO STAY UP LONGER PROBABLY DUE TO SOME WINGTIP VORTICES JUST NEAR TOUCHDOWN. IN RETROSPECT, A GAR MIGHT HAVE BEEN CONSIDERED AND SOMETHING SAID TO ATC ABOUT THE SPACING PROB BTWN OUR AIRPLANES. THE SFO COMMERCIAL PAGE 13-2A DOES NOT ALLOW FOR A LARGER AIRPLANE TO PASS ANOTHER AIRPLANE. SUPPLEMENTAL INFO FROM ACN 572296: LOCATION: FMS QUIET BRIDGE VISUAL APCH. I CONCUR WITH CAPT'S ASAP RPT. ALTHOUGH CONSTANT CREW COORD WAS NECESSARY DURING FMS ARR/APCH TO RWY 28R, AND LNDG DUE TO ATC SPACING OF B747-400 ON PARALLEL ARR TO RWY 28L, ARRIVING ON OUR WINGTIP AND SUBSEQUENTLY PASS US (SEE SFO FMII PAGE 13-2A) WE LANDED WITHOUT INCIDENT REMAINING ABOVE THE B747'S GLIDE PATH AND MAINTAINING AWARENESS OF POSSIBLE WINGTIP VORTICES.
