Narrative:
The autoplt on a 'coupled' ILS approach 'overshot' the localizer final while we were on our final vector heading and 'cleared for the approach.' as we were passing through the localizer course, both myself and the captain responded to each other and I disconnected the autoplt. About this time, ATC (atl approach) called us and told us to turn immediately to a heading of 180 degrees (left turn). This immediate action was warranted due to parallel approachs being in progress. As we were turning left to 180 degrees, the controller told us to maintain a heading of 240 degrees and intercept the localizer -- reclred for the approach. Also, the controller cleared us down to 2800 ft from 3500 ft. We continued the approach and landed without further incident. As a suggestion, I feel that we as pilots must be more aggressive when making turns and dscnts in the approach -- terminal environment.

Title: AUTOPLT COUPLED APCH. ACFT ON VECTORS FOR LOC INTERCEPT AND ACFT OVERSHOT LOC COURSE FLC DISCONNECTED AUTOPLT AND ATC ISSUED HDG VECTORS FOR ACFT SEPARATION.
Narrative: THE AUTOPLT ON A 'COUPLED' ILS APCH 'OVERSHOT' THE LOC FINAL WHILE WE WERE ON OUR FINAL VECTOR HDG AND 'CLRED FOR THE APCH.' AS WE WERE PASSING THROUGH THE LOC COURSE, BOTH MYSELF AND THE CAPT RESPONDED TO EACH OTHER AND I DISCONNECTED THE AUTOPLT. ABOUT THIS TIME, ATC (ATL APCH) CALLED US AND TOLD US TO TURN IMMEDIATELY TO A HDG OF 180 DEGS (L TURN). THIS IMMEDIATE ACTION WAS WARRANTED DUE TO PARALLEL APCHS BEING IN PROGRESS. AS WE WERE TURNING L TO 180 DEGS, THE CTLR TOLD US TO MAINTAIN A HDG OF 240 DEGS AND INTERCEPT THE LOC -- RECLRED FOR THE APCH. ALSO, THE CTLR CLRED US DOWN TO 2800 FT FROM 3500 FT. WE CONTINUED THE APCH AND LANDED WITHOUT FURTHER INCIDENT. AS A SUGGESTION, I FEEL THAT WE AS PLTS MUST BE MORE AGGRESSIVE WHEN MAKING TURNS AND DSCNTS IN THE APCH -- TERMINAL ENVIRONMENT.
