Narrative:

We were on radar vectors to runway 11L at msp. Simultaneous visual approachs were being conducted to 11R also. Our flight path took us left downwind to left base. We had been given a series of left turns and left on a 220 degree heading to descend to 3000 ft, traffic landing 11R was at 4000 ft. Approach control left us on the 220 degree heading too long, causing us to go through both extended ctrlines. We had the other aircraft on TCASII and visual. At this point ATC asked if we had runway 11L in sight and we turned hard left and descended for the approach. TCASII countered with a descend resolution and we continued to follow it. The other aircraft remained at 4000 ft. A post-flight telephone conversation with ATC indicated he gave us a late turn to final accompanied by too great of an intercept angle.

Title: ACR MLG SUFFERS A HDG TRACK DEV DURING RADAR VECTORING FROM TRACON APCH CTLR. POTENTIAL CONFLICT LTSS ENSUES IN THE DELAYED TURN.

Narrative: WE WERE ON RADAR VECTORS TO RWY 11L AT MSP. SIMULTANEOUS VISUAL APCHS WERE BEING CONDUCTED TO 11R ALSO. OUR FLT PATH TOOK US L DOWNWIND TO L BASE. WE HAD BEEN GIVEN A SERIES OF L TURNS AND L ON A 220 DEG HDG TO DSND TO 3000 FT, TFC LNDG 11R WAS AT 4000 FT. APCH CTL LEFT US ON THE 220 DEG HDG TOO LONG, CAUSING US TO GO THROUGH BOTH EXTENDED CTRLINES. WE HAD THE OTHER ACFT ON TCASII AND VISUAL. AT THIS POINT ATC ASKED IF WE HAD RWY 11L IN SIGHT AND WE TURNED HARD L AND DSNDED FOR THE APCH. TCASII COUNTERED WITH A DSND RESOLUTION AND WE CONTINUED TO FOLLOW IT. THE OTHER ACFT REMAINED AT 4000 FT. A POST-FLT TELEPHONE CONVERSATION WITH ATC INDICATED HE GAVE US A LATE TURN TO FINAL ACCOMPANIED BY TOO GREAT OF AN INTERCEPT ANGLE.
