Narrative:
During the arrival phase of flight we were being vectored by clt approach control for an ILS runway 18L approach at clt. There were multiple approachs in progress to runway 18L/right at the time of our arrival. We were given a 360 degree heading for downwind ILS runway 18L at clt. A descent was issued to 3600 ft MSL. At approximately 15 mi northeast, a left turn was issued by the controller to a heading of 280 degrees. During the turn the controller gave us a left turn to 360 degrees. When questioned, the controller said the left turn was to heading 260 degrees and cleared to descend to 3100 ft. We turned at 30 degree bank and began a descent to 3100 ft still east of the runway 18L localizer. Upon reaching 3100 ft RA with a don't climb descend, we saw target off our right side and confirmed the traffic visually (broken cloud). At the same time, the controller said turn left to a 360 degree heading, tight turn and climb to 3600 ft (aircraft position still east of localizer never intercepted). The wind at 3600 ft was 270 degrees at 18 KTS. We received a clear of conflict as we were turning through 180 degrees towards 360 degrees. Next approach was normal. I feel there needs to be better coordination between controllers regarding staggering altitudes and the effect of wind.

Title: ACR VECTORED INTO LTSS SIT WITH ACFT ON PARALLEL ILS APCH.
Narrative: DURING THE ARR PHASE OF FLT WE WERE BEING VECTORED BY CLT APCH CTL FOR AN ILS RWY 18L APCH AT CLT. THERE WERE MULTIPLE APCHS IN PROGRESS TO RWY 18L/R AT THE TIME OF OUR ARR. WE WERE GIVEN A 360 DEG HDG FOR DOWNWIND ILS RWY 18L AT CLT. A DSCNT WAS ISSUED TO 3600 FT MSL. AT APPROX 15 MI NE, A L TURN WAS ISSUED BY THE CTLR TO A HDG OF 280 DEGS. DURING THE TURN THE CTLR GAVE US A L TURN TO 360 DEGS. WHEN QUESTIONED, THE CTLR SAID THE L TURN WAS TO HDG 260 DEGS AND CLRED TO DSND TO 3100 FT. WE TURNED AT 30 DEG BANK AND BEGAN A DSCNT TO 3100 FT STILL E OF THE RWY 18L LOC. UPON REACHING 3100 FT RA WITH A DON'T CLB DSND, WE SAW TARGET OFF OUR R SIDE AND CONFIRMED THE TFC VISUALLY (BROKEN CLOUD). AT THE SAME TIME, THE CTLR SAID TURN L TO A 360 DEG HDG, TIGHT TURN AND CLB TO 3600 FT (ACFT POS STILL E OF LOC NEVER INTERCEPTED). THE WIND AT 3600 FT WAS 270 DEGS AT 18 KTS. WE RECEIVED A CLR OF CONFLICT AS WE WERE TURNING THROUGH 180 DEGS TOWARDS 360 DEGS. NEXT APCH WAS NORMAL. I FEEL THERE NEEDS TO BE BETTER COORD BTWN CTLRS REGARDING STAGGERING ALTS AND THE EFFECT OF WIND.
