Narrative:

An oncoming problem with carrier X crj aircraft exists in the atlanta terminal area. Weather conditions today were IFR with strong winds from the south at altitude (4000 ft; 200 degrees at 40 KTS) and southeast on the surface. Running triple ILS/prm approaches to runways 8L/9R/10. Runways 9R and 10 are separated by 4300 ft. I was utilizing a 080 degree or 085 degree heading to join the localizer at 180 KTS. Every carrier X aircraft turned onto the runway 10 localizer flew through the final approach course. Using the same headings and altitudes for other commercial aircraft resulted in successful capture of the localizer. This has been an ongoing problem since I have been at A80. We received an explanation at one time that the air crews were using the FMS to turn onto the localizer and it did not adequately compensate for the wind. Carrier briefed their pilots late last year and supposedly the situation should not recur. Unfortunately; it does occur almost every time there is any significant wind. The fact that runways 9R and 10 are only 4300 ft apart creates a significant safety issue. If the FMS cannot ensure the aircraft doesn't fly through the localizer; then it should not be used during this critical phase of flight.

Title: A80 Controller voiced concern regarding frequent instances of one air carrier's aircraft flying through the localizer during simultaneous approach procedures.

Narrative: An oncoming problem with Carrier X CRJ aircraft exists in the Atlanta terminal area. Weather conditions today were IFR with strong winds from the south at altitude (4000 FT; 200 degrees at 40 KTS) and southeast on the surface. Running triple ILS/PRM approaches to Runways 8L/9R/10. Runways 9R and 10 are separated by 4300 FT. I was utilizing a 080 degree or 085 degree heading to join the LOC at 180 KTS. Every Carrier X aircraft turned onto the Runway 10 LOC flew through the final approach course. Using the same headings and altitudes for other commercial aircraft resulted in successful capture of the LOC. This has been an ongoing problem since I have been at A80. We received an explanation at one time that the air crews were using the FMS to turn onto the LOC and it did not adequately compensate for the wind. Carrier briefed their pilots late last year and supposedly the situation should not recur. Unfortunately; it does occur almost every time there is any significant wind. The fact that Runways 9R and 10 are only 4300 FT apart creates a significant safety issue. If the FMS cannot ensure the aircraft doesn't fly through the LOC; then it should not be used during this critical phase of flight.
