HEAVY FREIGHT ACFT IS FORCED TO MANEUVER OFF FINAL APCH COURSE TO AVOID ACFT OVERSHOOTING FINAL TO THE PARALLEL RWY.

Narrative

ON APCH; ESTABLISHED/COUPLED TO ILS RWY 23L LOC; FIELD IN SIGHT AND CLRNC OF 'MAINTAIN 4000 FT CLRED FOR THE VISUAL TO RWY 23L APCH.' GS COMING DOWN TO INTERCEPT AND BOTH PM AND PF AWARE OF ACFT AT 1-2 O'CLOCK POS DSNDING FROM THE R (N); POINTED OUT IN THE COCKPIT AND ACKNOWLEDGED. WINDS FROM THE N AT 4000 FT WERE FROM THE NNW AT 35-45 KTS (OVERSHOOTING). WE WERE STILL ON APCH CTL WHEN THE ACFT APCHING FROM THE N WAS ASKED; 'ACR Y; DO YOU HAVE THE ACFT AT 12 O'CLOCK IN SIGHT?' LONG PAUSE AND THEN WE HEARD A 'NO' AS THE ACFT ROLLED BELLY UP AND SLIGHTLY HIGH TO CORRECT BACK ON COURSE. PM/FO CLICKED OFF THE AUTOPLT AND MADE SLIGHT MOVE TO S TO GIVE OVERSHOOTING ACFT 'ROOM.' DURING THIS THE CTLR ASKS US; 'ARE YOU ON A VISUAL?' ANSWER WAS AFFIRMATIVE AS WE MANEUVERED AND THEN STATED WE HAD ACR Y IN SIGHT AS HE CORRECTED BACK. ATC CAME BACK WITH DSND TO 3000 FT ON THE VISUAL. WE WERE JUST INTERCEPTING GS AT THE TIME AND DSNDED ON GS. CONTRIBUTING FACTORS IN MY JUDGEMENT WERE: OVERSHOOTING WINDS OF 45 KTS. TOO MUCH ATTN TO GETTING EYES OF THE ACFT OVERSHOOTING TO AN ESTABLISHED ACFT ON PARALLEL FINAL AND NOT ENOUGH ATTN TO DECONFLICTION OF VECTORED ACFT INTO A 'VISUAL' APCH BY APCH CTLR. SPD/RADIUS CTL OF INTERCEPT TAKEN FOR GRANTED AND NOT COMPENSATED FOR INCREASED GND SPD OF INTERCEPTING ACFT TO OVERSHOOT. EYES OUT AND SITUATIONAL AWARENESS OF 2 OUT OF 3 PARTIES.
