FLC IN AN ACR MLG ARE GIVEN A GAR BY APCH CTLR AFTER CREW FAILS TO VISUALLY ACQUIRE THE ARPT DURING A VISUAL APCH. PIC COMMENTED ON BEING TOO HIGH TO COMPLETE THE APCH.

Narrative

UPON ARR OVER VULCAN VOR WE WERE GIVEN A VECTOR HDG AND DSCNT TO 3000 FT MSL FOR A VISUAL APCH TO RWY 23. VISIBILITY WAS 6 MI IN HAZE AND FURTHER RESTR BY A SETTING SUN. ON ARR OVER VULCAN; I REALIZED I WAS HIGH FOR THE APCH AND BEGAN CONFIGURING FOR FINAL APCH DSCNT. AS WE WERE APCHING ROEBY I ASKED THE FO IF HE HAD THE FIELD. HE THOUGHT I SAID I HAD THE FIELD IN SIGHT. NEITHER OF US HAD THE FIELD IN SIGHT AT THIS TIME. WHEN THE CTLR ASKED IF WE COULD GET DOWN; THE FO SAID YES; WE HAD THE FIELD IN SIGHT. I KNEW THAT WE WERE HIGH AND NEEDED SOME ROOM TO GET DOWN. AT THIS POINT WE FLEW THROUGH LOC COURSE AND THE CTLR ASKED IF WE WERE DOING A 360 DEG TURN. I TOLD THE FO TO RELAY WE WERE MAKING A L TURN TO GET DOWN AND THE CTLR THEN GAVE US VECTORS AROUND TO REINTERCEPT THE LOC COURSE. 3 FACTORS CONTRIBUTED TO THIS EVENT: 1) HIGH APCH. 2) REDUCED VISIBILITY FROM THE HAZE AND LOW SUN ANGLE. 3) MISCOM IN THE COCKPIT. I SHOULD HAVE INTERCEPTED THE LOC COURSE AND CONTINUED THE APCH TO A POSSIBLE MISSED APCH WHEN I REALIZED NEITHER THE FO NOR MYSELF HAD THE FIELD VISUALLY.
