ATC RPTR CLAIMS THAT THE ARTS A3 PT 06 PROGRAM AT ATL TRACON RANDOMLY OMITS THE DESIGNATOR FOR HVY JETS AND B757'S. THE ANOMALY; WITH CORRECTIVE ACTION; HAS BEEN FORWARDED TO FAA HEADQUARTERS FOR REVIEW.

Narrative

THE CURRENT VERSION OF ARTS A3.06 DOES NOT ALWAYS CAPTURE THE SPECIAL DESIGNATOR FOR HVY JETS OR B757'S. THIS RESULTS IN LESS THAN STANDARD 'WAKE TURB' SEPARATION BEHIND THESE ACFT. I HAVE ADVISED FAA HEADQUARTERS OF THE PROB! TO DATE NO ACTION HAS BEEN TAKEN. THIS SAFETY ISSUE COULD CAUSE LOSS OF LIFE DUE TO ACFT BEING TOO CLOSE BEHIND HVY'S AND B757'S. I HAVE SUGGESTED THAT THE ARTS PROGRAM BE MODIFIED TO DEFAULT TO AN 'L' FOR B757'S AND AN 'H' FOR ALL HVY JETS. THIS WOULD AT LEAST INSURE THAT THE CTLR CAN EASILY IDENT THOSE ACFT AS NEEDING WAKE TURB SEPARATION. AS IT STANDS NOW; IT IS DEPENDENT ON AIRLINES TO FILE FLT PLANS CORRECTLY! CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR STATED THAT TRACON AUTOMATION ADVISED HIM THAT THE INFO THAT THE ARTS PROCESSES IS DERIVED FROM ZTL'S HOST COMPUTER. HE BELIEVES THAT THE FAA SHOULD HAVE A FAIL SAFE SYS TO SCREEN AND CORRECT THE INFO; WHEN NECESSARY; BECAUSE IT COMES FROM THE VARIOUS AIRLINES. THE PROB WAS STILL OCCURRING AS OF THE CALLBACK; BUT A SOLUTION IS BEING WORKED ON.
