GM1 Article 2(141) Visibility
ED Decision 2013/013/R
(a) The two distances which may be defined by a given visibility have
different values in the air of a given extinction coefficient.
Visibility based on seeing and recognising an object is represented
by the meteorological optical range (MOR) (Article
2(141)(a)). Visibility based on seeing and identifying
lights varies with the background illumination (Article
2(141)(b)).
(b) The definition of visibility applies to the observations of
visibility in local routine and special reports, to the observations
of prevailing and minimum visibility reported in METAR and SPECI, and
to the observations of ground visibility.
