Narrative:

While being vectored for the ILS to runway 35R, we were given a heading of 330 degrees and cleared to intercept the localizer -- cleared for the ILS runway 35R approach. I made the proper selections on the autoplt control panel but we crossed through the localizer before the autoplt could capture it. I immediately turned to a heading to re-intercept the localizer. ATC called to advise that we were left of course and possibly intercepting the parallel ILS. We informed them that we were re-intercepting the correct ILS but the turn and approach clearance were not issued in time for a normal intercept. We did not receive a TCASII advisory. However, ATC did divert an aircraft that was approaching on the parallel runway. ATC advised me that I need to be 'more careful' on simultaneous approachs. I advised them they need to do a better job with the vector and approach clearance. The only way I could have avoided flying through the localizer would have been to turn off the autoplt and roll to 45 degree bank. Since a traffic conflict was not involved, I elected to stay within normal flight parameters. Supplemental information from acn 487410: a lot of traffic is being jammed into den on closely spaced runways making it difficult for ATC to get every turn on right and these transport category airplanes only turn so fast.

Title: A LATE INTERCEPT CLRNC, UNFAVORABLE WIND AND ACFT LIMITATIONS RESULT IN A LOC OVERSHOOT ON ILS APCH TO DEN, CO.

Narrative: WHILE BEING VECTORED FOR THE ILS TO RWY 35R, WE WERE GIVEN A HEADING OF 330 DEGS AND CLRED TO INTERCEPT THE LOC -- CLRED FOR THE ILS RWY 35R APCH. I MADE THE PROPER SELECTIONS ON THE AUTOPLT CTL PANEL BUT WE CROSSED THROUGH THE LOC BEFORE THE AUTOPLT COULD CAPTURE IT. I IMMEDIATELY TURNED TO A HEADING TO RE-INTERCEPT THE LOC. ATC CALLED TO ADVISE THAT WE WERE L OF COURSE AND POSSIBLY INTERCEPTING THE PARALLEL ILS. WE INFORMED THEM THAT WE WERE RE-INTERCEPTING THE CORRECT ILS BUT THE TURN AND APCH CLRNC WERE NOT ISSUED IN TIME FOR A NORMAL INTERCEPT. WE DID NOT RECEIVE A TCASII ADVISORY. HOWEVER, ATC DID DIVERT AN ACFT THAT WAS APCHING ON THE PARALLEL RWY. ATC ADVISED ME THAT I NEED TO BE 'MORE CAREFUL' ON SIMULTANEOUS APCHS. I ADVISED THEM THEY NEED TO DO A BETTER JOB WITH THE VECTOR AND APCH CLRNC. THE ONLY WAY I COULD HAVE AVOIDED FLYING THROUGH THE LOC WOULD HAVE BEEN TO TURN OFF THE AUTOPLT AND ROLL TO 45 DEG BANK. SINCE A TFC CONFLICT WAS NOT INVOLVED, I ELECTED TO STAY WITHIN NORMAL FLT PARAMETERS. SUPPLEMENTAL INFO FROM ACN 487410: A LOT OF TFC IS BEING JAMMED INTO DEN ON CLOSELY SPACED RWYS MAKING IT DIFFICULT FOR ATC TO GET EVERY TURN ON RIGHT AND THESE TRANSPORT CATEGORY AIRPLANES ONLY TURN SO FAST.
