AN ACR MLG MADE 3 APCHS FOR 1 LNDG.

Narrative

CLT HAD TSTMS TO THE NW MOVING SE AND WE HAD SUCCESSFULLY NAVED AROUND THEM WITH APCH CTL'S HELP FOR DEVS. WE WERE ON A 100 DEG HDG AT 7000 FT BEING VECTORED FOR THE APCH TO RWY 18R. THERE WERE A LOT OF ACFT TALKING TO APCH AND HE WAS BLOCKED OUT SEVERAL TIMES. WE FINALLY GOT A LOWER ALT AND GOT THE ARPT IN SIGHT WITH APCH STILL VECTORING US; NOW TOWARD THE SW FOR A VISUAL APCH. WE COMPLETED THE LNDG CHKLIST SO AS TO GET THE BEST POSSIBLE DSCNT RATE. WE ALSO TOLD APCH WE COULD NOT MAKE A STRAIGHT-IN APCH; BUT COULD MAKE A R 270 DEG TURN AND THEN LINE UPON FINAL FOR RWY 18R. APCH COULD NOT DO THIS; SO WE CLEANED UP THE ACFT AND HE VECTORED US BACK TO ANOTHER SLOT IN LINE FOR RWY 18R AT 4000 FT. APCH KEPT US UP HIGH AGAIN FOR THE APCH; AND ASKED IF WE HAD THE ARPT WHEN HE TURNED US BACK ON FINAL. WE CONFIRMED WE HAD THE ARPT AND HE CLRED US FOR A VISUAL. AT THIS POINT WE NOTICED WE HAD A 30 KT TAILWIND. THE ACFT WOULD NOT DSND AT A SUFFICIENT RATE TO MAKE A GOOD APCH TO THE RWY. I TOLD THE CAPT THAT I WAS GOING TO HAVE TO GAR; BECAUSE I FELT WE COULD NOT MAKE A SAFE APCH. WE THEN EXECUTED THE MISSED APCH AND APCH CTL BROUGHT US AROUND FOR A THIRD APCH; WHICH WAS MADE PLANNING ON THE 30 KT TAILWIND AT ALT; AND CALM WINDS ON THE ARPT. ON THE APCH WE RECEIVED 10 KT FLUCTUATIONS OF AIRSPD; BUT THE LNDG WAS MADE UNEVENTFUL. I FEEL WE DID EVERYTHING POSSIBLE TO MAKE A SAFE BUT GOOD RATE OF DSCNT. HOWEVER; APCH CTL SEEMED TO BE OVERLOADED WITH TFC; CAUSING PROBS WITH THE SYS; WHICH CAUSED US TO HAVE TO EXECUTE 3 APCHS FOR 1 LNDG. ALSO; SHORTLY AFTER LNDG; THE TFC PATTERN WAS SHIFTED TO A NORTHERLY FLOW; AS THE WIND PICKED UP AND SHIFTED OUT OF THE N; ON THE ARPT.
