Narrative:
Aircraft was vectored for an approach to runway 17R at den. WX was essentially VFR but hazy conditions existed during approach. ILS runway 17R was tuned with a vector angle of approximately 70 degrees when the aircraft was cleared for a visual approach. Since hazy conditions existed, runway 16 came into view first because it is located 2 mi north of parallel runway 17R. Captain began turn to runway 17R at same time localizer was crossed (intercept angle approximately 70 degrees). Bank angle was increased to maximum at same time den tower called overshoot of final to runway 17R. Tower did report another aircraft inbound to runway 16. I picked aircraft up visually during my turn to runway 17R. No conflict or evasive action needed since already correcting in a 30 degree angle of bank toward runway 17R and aircraft inbound to runway 16 appeared well clear and at a different altitude.

Title: DC8 FLC VISUALLY ACQUIRED A RWY AND DRIFTED THROUGH THE ASSIGNED RWY ON APCH TO DIA.
Narrative: ACFT WAS VECTORED FOR AN APCH TO RWY 17R AT DEN. WX WAS ESSENTIALLY VFR BUT HAZY CONDITIONS EXISTED DURING APCH. ILS RWY 17R WAS TUNED WITH A VECTOR ANGLE OF APPROX 70 DEGS WHEN THE ACFT WAS CLRED FOR A VISUAL APCH. SINCE HAZY CONDITIONS EXISTED, RWY 16 CAME INTO VIEW FIRST BECAUSE IT IS LOCATED 2 MI N OF PARALLEL RWY 17R. CAPT BEGAN TURN TO RWY 17R AT SAME TIME LOC WAS CROSSED (INTERCEPT ANGLE APPROX 70 DEGS). BANK ANGLE WAS INCREASED TO MAX AT SAME TIME DEN TWR CALLED OVERSHOOT OF FINAL TO RWY 17R. TWR DID RPT ANOTHER ACFT INBOUND TO RWY 16. I PICKED ACFT UP VISUALLY DURING MY TURN TO RWY 17R. NO CONFLICT OR EVASIVE ACTION NEEDED SINCE ALREADY CORRECTING IN A 30 DEG ANGLE OF BANK TOWARD RWY 17R AND ACFT INBOUND TO RWY 16 APPEARED WELL CLR AND AT A DIFFERENT ALT.
