AN ACR SMT CREW THOUGHT THAT IT LANDED WITHOUT PROPER RVR.

Narrative

WHILE ON IFR CLRNC TO OTZ; WX WAS RECEIVED FROM OTZ FSS AND WAS DETERMINED TO BE GOOD FOR THE APCH. UPON INITIAL CONTACT WITH FSS; WHILE JOINING THE ARC FOR THE ILS RWY 8; FSS RPTED A CESSNA 207 HOLDING FOR SPECIAL VFR WINDS 160 DEGS AT 23 KTS; ALTIMETER SETTING 29.61 PREVAILING VISIBILITY GIVEN AT 3/4 VARIABLE 1/2 TO 1 1/4 INCHES. WE RPTED THE FAF INBOUND AND ASKED IF THEY WERE STILL RPTING 3/4 MI. FSS INDICATED 3/4 MI WAS STILL THE PREVAILING VISIBILITY. WE CONTINUED THE APCH TO THE GND; BREAKING OUT OF THE OBSCURATION AT 700-800 FT. FORWARD VISIBILITY WAS 1 1/2 - 2 MI AS SEEN FROM THE COCKPIT. UPON LNDG AND POSTFLT BRIEFING; WE REALIZED THAT RVR WAS CTLING AND USING PREVAILING VISIBILITY WAS CONTRARY TO FARS. COM WAS CONGESTED; MONITORING 122.9 WAS ESSENTIAL TO KEEP TRACK OF VFR ACFT IN MVFR AND IFR CONDITIONS. RVR RPTS OF 2800- 2400 FT WERE GIVEN TWICE TO OTHER ACFT; BUT WE DID NOT HEAR (ASSIMILATE) DUE TO RADIO CONGESTION AND LISTENING FOR OUR OWN CALL SIGN. NO RVR RPTS WERE GIVEN TO US AT ANY TIME (DETERMINED BY LISTENING TO FSS TAPES).
