Narrative:
While approaching sfo from south on big sur arrival we were vectored off at 6000 ft 250 KTS for a visual to runway 28L. Traffic was pointed out that was from north on a left downwind/left base to runway 28R. (A 747). We did not call traffic. We continued to be vectored for runway 28L visual. The 747 called us in sight after we were lined up on runway 28L and he was on runway 28R just behind us. We were cleared for runway 28L visual. Inside FAF the 747 passed us up and landed 1/4 mi ahead of us on runway 28R. The wind was from the left (260 degrees 15 KTS). If the wind had been from the right I would not have continued the approach. A heavy 747 should not be allowed to pass any aircraft on the opposite runway at sfo (runway left/right). The spacing (lateral) is just too close. This procedure is not safe. Next time I will not accept a runway 28 visual when I know a 747 is on the opposite runway. I can only assume that it was legal (as far as the tower was concerned) because the 747 called us in sight. The separation was on his sighting not mine.

Title: 747 PASSED RPTR IN 757 DOING SIDE BY SIDE CHARTED VISUALS TO SFO RWYS 28L AND RWY 28R RESULTING IN THE RPTR CONCERN FOR WAKE TURB AT SO CLOSE A PROX.
Narrative: WHILE APCHING SFO FROM S ON BIG SUR ARR WE WERE VECTORED OFF AT 6000 FT 250 KTS FOR A VISUAL TO RWY 28L. TFC WAS POINTED OUT THAT WAS FROM N ON A L DOWNWIND/L BASE TO RWY 28R. (A 747). WE DID NOT CALL TFC. WE CONTINUED TO BE VECTORED FOR RWY 28L VISUAL. THE 747 CALLED US IN SIGHT AFTER WE WERE LINED UP ON RWY 28L AND HE WAS ON RWY 28R JUST BEHIND US. WE WERE CLRED FOR RWY 28L VISUAL. INSIDE FAF THE 747 PASSED US UP AND LANDED 1/4 MI AHEAD OF US ON RWY 28R. THE WIND WAS FROM THE L (260 DEGS 15 KTS). IF THE WIND HAD BEEN FROM THE R I WOULD NOT HAVE CONTINUED THE APCH. A HVY 747 SHOULD NOT BE ALLOWED TO PASS ANY ACFT ON THE OPPOSITE RWY AT SFO (RWY L/R). THE SPACING (LATERAL) IS JUST TOO CLOSE. THIS PROC IS NOT SAFE. NEXT TIME I WILL NOT ACCEPT A RWY 28 VISUAL WHEN I KNOW A 747 IS ON THE OPPOSITE RWY. I CAN ONLY ASSUME THAT IT WAS LEGAL (AS FAR AS THE TWR WAS CONCERNED) BECAUSE THE 747 CALLED US IN SIGHT. THE SEPARATION WAS ON HIS SIGHTING NOT MINE.
