ACCUSED BY UNKNOWN OBSERVERS OF FLYING VFR IN IMC AT AN UNCTLED ARPT.

Narrative

I GAVE A PVT PLT A BIENNIAL FLT REVIEW ON THIS FLT. I ELECTED TO STAY IN THE PATTERN DUE TO THE MARGINAL CONDITIONS. BEFORE WE LEFT THE SCHOOL; WE LISTENED TO THE AWOS OF FDK AND THE AWOS INDICATED VFR CONDITIONS: MORE THAN 3 MI VISIBILITY AND MORE THAN 1000 FT CEILING. WITH THAT KNOWLEDGE; WE AGREED TO DO AN HR OF PATTERN WORK. WE TAXIED OUT AFTER THE PREFLT WALKAROUND AND LISTENED ONE MORE TIME TO THE AWOS. THIS TIME IT INDICATED THAT THERE WAS 2 1/2 MI VISIBILITY AND MORE THAN 1000 FT CEILING (FIELD ELEVATION = 305 FT). WE DECIDED TO FLY A LOW PATTERN AT 1000 FT MSL WHICH IS 700 FT AGL AND THEREFORE FLY UNDER THE FLT RULES THAT APPLY IN CLASS G AIRSPACE: 1 MI VISIBILITY AND CLR OF CLOUDS (DAYTIME). WE TOOK OFF AND HAD NO TROUBLE TO PERFORM A SAFE FLT UNDER VFR CONDITIONS. IT NEVER DETERIORATED AND; LATER ON; THE WX ACTUALLY IMPROVED. WE DID OUR POS RPTS ON EACH LEG AND MONITORED THE UNICOM FREQ FOR ANY OTHER TFC. 2 PEOPLE ON THE GND (THERE WAS NOBODY IN THE AIR) DECIDED TO RPT US TO THE FAA; STATING THAT WE WERE FLYING IN IFR CONDITIONS. NOT TRUE!
