A note to weather information card section “GAFOR” which states that weather class “O” does not necessarily permit night-VFR flying

Safety Investigation Authority, Finland (SIAF) recommends that the Finnish Meteorological Institute augment its Finnish Meteorological Services publication weather card (the so-called “weather accordion”) by adding a note to section “GAFOR” which states that weather class “O” does not necessarily permit night-VFR flying outside aerodrome control zones or beyond the landing pattern of an uncontrolled airstrip.
