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.
