BEFORE CHANGING THE RWY APCH DIRECTION; THE TWR CTLR QUESTIONS THE PLT OF A BEECH 90 KING AIR AS TO HOW SOON THE RWY WAS SIGHTED BEFORE LNDG FROM A BACK COURSE INST APCH.

Narrative

WHILE ON THE FAT BACK COURSE LOC APCH; I WAS ABLE TO PICK UP THE ARPT JUST OUTSIDE THE MISSED APCH WHICH; IN THIS CASE; WAS .5 DME ON THE LOC. I WAS 10 KTS OUT OF THE WHITE ARC AND BY THE TIME I SLOWED TO FLAPS MAX SPD; I WAS OVER THE THRESHOLD. I DSNDED AND LANDED UNEVENTFULLY; ALTHOUGH I TOUCHED DOWN FURTHER DOWN THE RWY THAN I NORMALLY PLAN. TWR CTL QUERIED ME (ON A DISCRETE FREQ) ABOUT THE METEOROLOGICAL CONDITIONS AND AS TO WHERE I PICKED UP THE RWY. I TOLD HIM 'ABOUT .1 MI' (WHAT I MEANT WAS .1 FROM THE MISSED APCH AND NOT FROM THE RWY). TWR THEN ASKED ME IF THOUGHT THE BACK COURSE SHOULD BE USED FOR SUBSEQUENT ACFT. I REPLIED THAT THE WX WE ENCOUNTERED WAS WORSE THAN WHAT ATIS WAS RPTING AND THAT; WIND PERMITTING (IT WAS LESS THAN 8 KTS) THE ILS MIGHT BE A BETTER CHOICE. HE REPLIED THAT HE LIKED 'PLT INPUT' PRIOR TO MAKING CHANGES IN THE APCH TO BE USED. CONCERNS: I WAS BOTHERED THAT THE WX WAS MUCH LOWER THAN ATIS RPTED. I WAS THE FIRST ACFT TO ENCOUNTER THIS DETERIORATED CEILING. I WAS TROUBLED ABOUT HAVING A CONVERSATION WITH TWR CTL ON A DISCRETE FREQ; AND I WONDERED IF HE WAS INTERESTED IN MY INPUT OR WAS HE TRYING TO PRY INFO; TO MY DETRIMENT; FROM ME. I WAS CAUGHT BTWN EXECUTING THE MISSED APCH OR EFFECTING THE LNDG. NEVER IN DOUBT ABOUT THE SAFE OUTCOME OF DSCNT AND LNDG; I EVEN HAD TO ADD PWR TO REACH THE TAXI END OF THE RWY.
