Narrative:
Cleared for approach on G/south, 1 DOT to left of localizer ILS 8R. Widebody transport on approach 9R drifted into our flight path forcing us to stop descent at 3700'. Notified tower. Cleared to 4000' contact approach next approach normal. Widebody transport drift indicated a strong conflict with no corrective action apparent when we elected to abort the approach.

Title: FLT CREW OF WDB ON DESCENT AND APCH TO ATL 8R ABORTED APCH WHEN WDB SEEN DRIFTING INTO THEIR FLT PATH.
Narrative: CLRED FOR APCH ON G/S, 1 DOT TO L OF LOC ILS 8R. WDB ON APCH 9R DRIFTED INTO OUR FLT PATH FORCING US TO STOP DSCNT AT 3700'. NOTIFIED TWR. CLRED TO 4000' CONTACT APCH NEXT APCH NORMAL. WDB DRIFT INDICATED A STRONG CONFLICT WITH NO CORRECTIVE ACTION APPARENT WHEN WE ELECTED TO ABORT THE APCH.
