Narrative

IFR FLT PLAN FILED FROM N67 (PA) TO 58N; A FIELD W/O AN INSTRUMENT APCH. VIS WAS 1.5-2 MI DUE TO HAZE FROM HOT SUMMER WX. ALTERNATE DEST WAS N76 (ABOUT 3 MI AWAY) THAT HAS AN INSTRUMENT APCH. CTLR WAS ASSUMING THAT A VISUAL APCH WAS NOT POSSIBLE (HARRISBURG; 126.45) AND ASKED SEVERAL TIMES IF I WISHED TO PROCEED TO N76 FOR AN APCH. ACTUALLY; BY VECTORS; CTLR HAD MY ACFT 3 MI S OF THE FIELD; AND HE TURNED ME TOWARD THE FIELD AND ASKED AGAIN ABOUT AN APCH TO N76. AT THIS POINT; I HAD 58N IN SIGHT AND TURNED TO MAKE A VISUAL APCH AND LOSE SOME ALT. AT THIS POINT; THE CTLR ASKED IF I HAD TURNED AND EXPRESSED SURPRISE THAT I HAD. IT WAS IMPORTANT TO KEEP THE FIELD IN SIGHT WITH THE LOW VIS. THE LNDG AND APCH WERE MADE W/O INCIDENT; AND THE IFR FLT PLAN WAS CANCELLED ON FINAL APCH. THE SITUATION WAS CONFUSING MAINLY BECAUSE OF THE ASSUMPTION ON THE PART OF THE CTLR THAT THE REQUIRED VIS WAS NOT PRESENT. THIS INFO WAS PRESUMABLY FROM THE WX DATA AT HARRISBURG. MY ERROR WAS IN NOT RPTING THE FIELD IN SIGHT EARLIER. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING: RPTR STATES THIS WAS A VERY HUMBLING EXPERIENCE. NOW KNOWS HE SHOULD HAVE CANCELLED IFR BEFORE TURNING TO DEST ARPT. FREQ VERY BUSY AND COULD NOT GET THROUGH TO ATC; SO TURNED TO KEEP FIELD IN SIGHT. EXTREME HAZE CONDITION.
