Narrative:

Left mem for 2i4 at XA30Z, uneventful flight clear until 40 mi southwest of 2i4, ground fog around destination, starting to break up, WX improving, however, reported WX at 2i4: west 2X 1/8 calm wind. Was given clearance for ILS runway 4 (minimums: 20 1/2 mi) approach, could see ground in spots. They had not updated WX when I shot approach. Upon reaching minimum descent altitude, looked up saw approach lights and threshold. My in-flight visibility was 3/4 mi. Landed uneventfully. Taxied into FBO, got fuel. One of the lcls hanging around lounge, was telling me I landed below minimums. Was told tower reports to FAA all lndgs less than 1/2 mi visibility. I felt quite justified in landing as I told tower that my in-flight visibility was 3/4 mi on taxi-in and I had runway environment in sight at decision altitude. I know that visibility minimums control landing unless a ceiling is required, but that means flight visibility, as a part 91 operator, I can begin approachs if WX is reported below minimums. Without RVR on a runway observed visibility can be quite variable, especially fog in morning as sun rises. I don't know if FAA will pursue it or not. I wish WX observer at some of these smaller fields were more timely especially when it is changing rapidly.

Title: LCL PLT ALLEGED THAT PART 91 PLT LANDED BELOW VISIBILITY MINIMUMS.

Narrative: LEFT MEM FOR 2I4 AT XA30Z, UNEVENTFUL FLT CLR UNTIL 40 MI SW OF 2I4, GND FOG AROUND DEST, STARTING TO BREAK UP, WX IMPROVING, HOWEVER, RPTED WX AT 2I4: W 2X 1/8 CALM WIND. WAS GIVEN CLRNC FOR ILS RWY 4 (MINIMUMS: 20 1/2 MI) APCH, COULD SEE GND IN SPOTS. THEY HAD NOT UPDATED WX WHEN I SHOT APCH. UPON REACHING MINIMUM DSCNT ALT, LOOKED UP SAW APCH LIGHTS AND THRESHOLD. MY INFLT VISIBILITY WAS 3/4 MI. LANDED UNEVENTFULLY. TAXIED INTO FBO, GOT FUEL. ONE OF THE LCLS HANGING AROUND LOUNGE, WAS TELLING ME I LANDED BELOW MINIMUMS. WAS TOLD TWR RPTS TO FAA ALL LNDGS LESS THAN 1/2 MI VISIBILITY. I FELT QUITE JUSTIFIED IN LNDG AS I TOLD TWR THAT MY INFLT VISIBILITY WAS 3/4 MI ON TAXI-IN AND I HAD RWY ENVIRONMENT IN SIGHT AT DECISION ALT. I KNOW THAT VISIBILITY MINIMUMS CTL LNDG UNLESS A CEILING IS REQUIRED, BUT THAT MEANS FLT VISIBILITY, AS A PART 91 OPERATOR, I CAN BEGIN APCHS IF WX IS RPTED BELOW MINIMUMS. WITHOUT RVR ON A RWY OBSERVED VISIBILITY CAN BE QUITE VARIABLE, ESPECIALLY FOG IN MORNING AS SUN RISES. I DON'T KNOW IF FAA WILL PURSUE IT OR NOT. I WISH WX OBSERVER AT SOME OF THESE SMALLER FIELDS WERE MORE TIMELY ESPECIALLY WHEN IT IS CHANGING RAPIDLY.
