visibility. Means the vertical and horizontal sight distance. This policy expressly excludes coverage for lost diving days due to limited visibility regardless of the weather conditions causing the poor “visibility”.

More Definitions of visibility
visibility means the ability, as determined by atmospheric conditions and expressed in units of distance, to see and identify prominent unlighted objects by day and prominent lighted objects by night;
visibility means the physical attributes of a sign and its contents that allow for detection at a given distance, although legibility may be uncertain.

visibility means the ability, as determined by atmospheric condition and expressed in units of distance, to see and identify prominent unlighted objects by day and prominent lighted objects by night;
visibility means visibility for aeronautical purposes is the greater of:a) the greatest distance at which a black object of suitable dimensions, situated near the ground, can be seen and recognized when observed against a brightbackground;b) the greatest distance at which lights in the vicinity of 1 000 candelas can be seen and identified against an unlit background. GM1 Article 2(141) Visibility(a) The two distances which may be defined by a given visibility have different values in air of a given extinction coefficient. Visibility based on seeing and recognizing 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. ‘visual meteorological conditions’ mean meteorological conditions expressed in terms of visibility, distance from cloud, and ceiling, equal to or better than specified minima. ‘VMC’ means the symbol used to designate visual meteorological conditions. Article 3ComplianceThe Member States shall ensure compliance with the common rules and provisions set out in the Annex to this Regulation without prejudice to the flexibility provisions contained in Article 14 of the Regulation (EC) No 216/2008 and the safeguards contained in Article 13 of Regulation (EC) No 549/2004.

visibility means making transparent who is doing the spending, how much they are spending, on what they are spending, and with whom they are spending (Bushell, 2004)
visibility means the degree of perceived clarity when viewing objects at a distance. Visibility depends on light extinction, visual range includes perceived changes in contrast, or coloration, and texture of elements in a scene.EPA’s Response: This edit to the rule text has been made.
