Your assumption is a pretty good rule of a thumb, esp. if applied only
to single-runway (<4000ft) non-towered airports. Segmented circle ALWAYS
has a (usually lighted at night) wind sock as far as I have seen.
However, notable exception might be any airport with an obvious wind
shift along the runway, because of mountains, close terrain "texture
changes" (forest/field/buildings) etc. Anyway, such wind shift won't be
detected by fgfs as it is today.
