Narrative:
On approach to sfo runway 28R air carrier X sequenced behind an airplane arriving from the north. We were straight in from the southeast. Approach did a poor job and we ended up '3 1/2 mi behind a B747' with calm winds. I said we could not accept that. No comment from tower. I repeated that we could not accept that tight an interval. No comment. I requested an s-turn and from our angle, and after checking TCASII and the area behind aircraft abeam us approaching runway 28L, we did an s-turn to the south, left, and crossed centerline of runway 28L. Tower said we should have done an s-turn to the north. They said we were told that earlier, but we did not hear the north s-turn call from tower. Earlier, tower had made a comment about our radio being unclr. An uneventful landing on runway 28R ensued approach got us too close to the 747. Our problem: go around or s-turn? I should have s-turned away from the other runway. I should have heard the tower transmission. Sfo problem: saturation. Approach should have told us to go around. I think that 3 1/2 mi is less than minimum to follow a heavy.

Title: MULTIPLE RWY OP PARALLEL RWYS ACR X MADE S-TURN ON FINAL APCH IN FRONT OF TFC FOR THE PARALLEL RWY.
Narrative: ON APCH TO SFO RWY 28R ACR X SEQUENCED BEHIND AN AIRPLANE ARRIVING FROM THE N. WE WERE STRAIGHT IN FROM THE SE. APCH DID A POOR JOB AND WE ENDED UP '3 1/2 MI BEHIND A B747' WITH CALM WINDS. I SAID WE COULD NOT ACCEPT THAT. NO COMMENT FROM TWR. I REPEATED THAT WE COULD NOT ACCEPT THAT TIGHT AN INTERVAL. NO COMMENT. I REQUESTED AN S-TURN AND FROM OUR ANGLE, AND AFTER CHKING TCASII AND THE AREA BEHIND ACFT ABEAM US APCHING RWY 28L, WE DID AN S-TURN TO THE S, L, AND CROSSED CTRLINE OF RWY 28L. TWR SAID WE SHOULD HAVE DONE AN S-TURN TO THE N. THEY SAID WE WERE TOLD THAT EARLIER, BUT WE DID NOT HEAR THE N S-TURN CALL FROM TWR. EARLIER, TWR HAD MADE A COMMENT ABOUT OUR RADIO BEING UNCLR. AN UNEVENTFUL LNDG ON RWY 28R ENSUED APCH GOT US TOO CLOSE TO THE 747. OUR PROB: GAR OR S-TURN? I SHOULD HAVE S-TURNED AWAY FROM THE OTHER RWY. I SHOULD HAVE HEARD THE TWR XMISSION. SFO PROB: SATURATION. APCH SHOULD HAVE TOLD US TO GAR. I THINK THAT 3 1/2 MI IS LESS THAN MINIMUM TO FOLLOW A HVY.
