A80 CTLR DESCRIBED TCAS RA THAT RESULTED FROM APCH PROC THAT REQUIRES ACFT TO SIDESTEP FROM RWY 9L TO RWY 9R TO COMPLY WITH SIMULTANEOUS APCH MINIMUMS.

Narrative

ACR X WAS ON FINAL FOR ILS RWY 9L; SIDESTEP TO RWY 9R. ACR Y ON FINAL FOR ILS RWY 10. ACR X RPTS RWY 9R IN SIGHT AND INSTEAD; FLIES TOWARDS RWY 10. THIS SEEMS TO OCCUR ONCE OR TWICE A WEEK AT ATL. RWY 9R/27L WAS BUILT 4200 FT FROM THE NEW RWY 10/28. ACCORDING TO THE FAA REGS; THE RWYS MUST BE 4300 FT APART TO CONDUCT SIMULTANEOUS OPS. RATHER THAN ALLOW A WAIVER FOR THE 100 FT; THE FAA IS FORCING PLTS AND CTLRS TO CONDUCT AN APCH TO A DEP RWY (9L/27R) FULL OF AIRPLANES; AND AT THE LAST MIN; SIDESTEP TO THE ADJACENT RWY 9R/27L. THE PLTS ARE HAVING TO TRANSITION FROM A PRECISION APCH TO HAND FLYING THE ACFT AND ARE MISTAKENLY AIMING FOR THE WRONG RWY (10/28). IF THE WX GETS BELOW VFR; THE SITUATION BECOMES MORE COMPLEX AS OUR DEP RWY (9L/27R) BECOMES AN ARR RWY AND THE ARR RWY (9R/27L) IS USED FOR DEPS. THIS MEANS THAT IN THE WORST WX CONDITIONS; HUNDREDS OF DEPS MUST CROSS A BUSY ARR RWY TO GET THEIR DEP RWY. IN ADDITION TO CREATING THE OPPORTUNITY FOR A RWY INCURSION OR GAR'S; THE PLTS HAVE TO TAKE OFF ON A RWY (9R/27L) THAT IS 3000 FT SHORTER THAN (9L/27R); WHICH FURTHER REDUCES THE MARGIN OF SAFETY. I BELIEVE IT WOULD BE SAFER FOR THE FAA TO ALLOW A WAIVER FOR THE ACFT TO LAND STRAIGHT IN ON ALL 3 RWYS (26R; 27L; AND 28 OR 8L; 9R AND 10) RATHER THAN REQUIRE A SIDESTEP. THE FAA HAS CREATED A CONFUSING; COMPLEX; AND DANGEROUS SITUATION FOR THE PLTS AND CTLRS AT ATLANTA TWR AND TRACON. SUPPLEMENTAL INFO FROM ACN 714053: ZTL CLRED OUR FLT TO SHOOT AN ILS TO RWY 9L SIDESTEP TO RWY 9R BEHIND A HVY B767. FO WAS FLYING. NEAR THE FAF; THE FO STATED HE SAW THE RWYS AND STARTED THE SIDESTEP. I NOTED WE HAD AN ACFT ON THE TCAS TO OUR R AT +100 FT. THE ACFT WAS LNDG RWY 10. AS THE FO MANEUVER WE ENCOUNTERED SOME WAKE TURB WHICH RESULTED IN THE R WING DIPPING. I DIRECTED HIM TO COME L MORE BECAUSE OF THE ACFT ON THE TCAS. WE THEN RECEIVED A TA FROM THE TCAS ON THE ACFT TO OUR R. I TOOK CTL AND INITIATED AN IMMEDIATE GAR WITH A CLBING L TURN AWAY FROM TFC.
