AN ACR B757 FOUND ITSELF IN TROUBLE MAKING A 'SLAM DUNK' VISUAL APCH AT SFO.

Narrative

WE WERE ON A GOLDEN GATE 3 ARR TO SFO AND CLRED TO CROSS LESTR AT 11000 FT AND 250 KTS; THEN A DSCNT TO 6000 FT; THEN DSND TO 4000 FT AND A BASE TURN TO 180 DEGS. TURNING THROUGH ABOUT 120 DEGS; WE WERE GIVEN A TURN TO 280 DEGS. FO CALLED THE FIELD IN SIGHT FOR THE VISUAL (QUIET BRIDGE) TO RWY 28R. APCH CTL CALLED TFC (LIGHT TWIN) ON A VISUAL TO RWY 28L. WE SAW THE TFC AT ABOUT 11-12 O'CLOCK; LEVEL TO SLIGHTLY HIGH. I SAW THAT HORIZ AND VERT SEPARATION WAS GOING TO BE A PROB; SO I INCREASED THE BANK ANGLE FROM 25-30 DEGS TO ABOUT 45-50 DEGS AND KEPT THE DSCNT RATE AT ABOUT 1800 FPM. TCASII SAID 'MONITOR VERT SPD;' THEN 'INCREASE DSCNT' (I INCREASED TO ABOUT 2500-2800 FPM) AND ROLLED OUT ON ABOUT A 310 DEG HDG AND THEN WE GOT THE 'CLR OF CONFLICT' FROM THE TCASII AND MADE A NORMAL LNDG ON RWY 28R. I FEEL THAT THIS PROB AROSE FROM : 1) CLASSIC 'SLAM DUNK' INTO SFO DOESN'T WORK VERY WELL FOR AERODYNAMICALLY EFFICIENT ACFT LIKE THE 757 -- NEED MORE CTLR EDUCATION/PLT DIALOGUE. 2) WIND AT ALT WAS FROM THE N AT 30-40 KTS WHICH FURTHER CONTRIBUTED TO THE TFC CONFLICT. 3) I FEEL TFC SHOULD BE STAGGERED 1/4 TO 1/2 MI WHEN PARALLEL APCHS ARE IN USE AT SFO. 4) IT'S HARD TO 'SLOW DOWN;' 'GO DOWN;' AND TURN ALL AT ONCE IN THE 757 -- AGAIN; MORE CTLR AWARENESS AND PRIOR PLANNING.
