Narrative:

On vectors to a visual approach, the controller gave us a turn to final for the visual to runway 16 that was too close to the extended centerline for us to complete without an overshoot. This was not apparent to us until the turn was in progress. There was a strong (approximately 30-40 KT) wind that was from a westerly direction that the controller may not have accounted for. Another aircraft was turning final to runway 17R from the other side of the airport. In our turn we were blown into the approximately extended centerline of runway 17R. I saw the aircraft but when the TCASII gave us an RA we responded with a climb and advised ATC. After receiving a clear of conflict we completed our visual approach successfully to runway 16.

Original NASA ASRS Text

Title: AN NMAC OCCURS AS AN ACR MLG IS GIVEN A LATE TURN BY APCH CTLR FOR A VISUAL TO RWY 16, DEN. ACFT X OVERSHOT THE RWY CTRLINE AND CONFLICTS WITH ARR TFC FOR RWY 17.

Narrative: ON VECTORS TO A VISUAL APCH, THE CTLR GAVE US A TURN TO FINAL FOR THE VISUAL TO RWY 16 THAT WAS TOO CLOSE TO THE EXTENDED CTRLINE FOR US TO COMPLETE WITHOUT AN OVERSHOOT. THIS WAS NOT APPARENT TO US UNTIL THE TURN WAS IN PROGRESS. THERE WAS A STRONG (APPROX 30-40 KT) WIND THAT WAS FROM A WESTERLY DIRECTION THAT THE CTLR MAY NOT HAVE ACCOUNTED FOR. ANOTHER ACFT WAS TURNING FINAL TO RWY 17R FROM THE OTHER SIDE OF THE ARPT. IN OUR TURN WE WERE BLOWN INTO THE APPROX EXTENDED CTRLINE OF RWY 17R. I SAW THE ACFT BUT WHEN THE TCASII GAVE US AN RA WE RESPONDED WITH A CLB AND ADVISED ATC. AFTER RECEIVING A CLR OF CONFLICT WE COMPLETED OUR VISUAL APCH SUCCESSFULLY TO RWY 16.
