Narrative:
While working tar-D (feeder into atl) radar position simultaneous dual stars; separated by only 5 mi; were being conducted all to the same runway. Aircraft were slowing to 250 KTS at the 40 DME fix of A80 airspace. Both heavy aircraft were side-by-side and indicating 400 KTS. We have approximately 10-15 mi of airspace to get these aircraft in trail to feed the one runway. At the same time the 2 heavy aircraft crossed the 40 DME fix; 6 mi in trail of the MD10 is a crj indicating 400 KTS. This procedure of simultaneous dual stars to one runway is unsafe and puts undue stress and added workload to the controller.

Title: A80 CTLR VOICED CONCERN REGARDING DUAL ARR RTES FOR THE SAME RWY AT ATL; CLAIMING AIRSPACE CONSTRAINTS LIMIT ABILITY TO SEPARATE ACFT.
Narrative: WHILE WORKING TAR-D (FEEDER INTO ATL) RADAR POS SIMULTANEOUS DUAL STARS; SEPARATED BY ONLY 5 MI; WERE BEING CONDUCTED ALL TO THE SAME RWY. ACFT WERE SLOWING TO 250 KTS AT THE 40 DME FIX OF A80 AIRSPACE. BOTH HVY ACFT WERE SIDE-BY-SIDE AND INDICATING 400 KTS. WE HAVE APPROX 10-15 MI OF AIRSPACE TO GET THESE ACFT IN TRAIL TO FEED THE ONE RWY. AT THE SAME TIME THE 2 HVY ACFT CROSSED THE 40 DME FIX; 6 MI IN TRAIL OF THE MD10 IS A CRJ INDICATING 400 KTS. THIS PROC OF SIMULTANEOUS DUAL STARS TO ONE RWY IS UNSAFE AND PUTS UNDUE STRESS AND ADDED WORKLOAD TO THE CTLR.
