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 bright background; b) the greatest distance at which lights in the vicinity of 1 000 candelas can be seen and identified against an unlit background. The two distances have different values in air of a given extinction coefficient, and the latter b) varies with the background illumination. The former a) is represented by the meteorological optical range (MOR). 5, record 1, English, - visibility

La visibilité pour l'exploitation aéronautique correspond à la plus grande des deux valeurs suivantes : a) la plus grande distance à laquelle on peut voir et reconnaître un objet noir de dimensions appropriées situé près du sol lorsqu'il est observé sur un fond lumineux; b) la plus grande distance à laquelle on peut voir et identifier des feux d'une intensité voisine de 1 000 candelas lorsqu'ils sont observés sur un fond non éclairé. Les deux distances sont différentes pour un coefficient d'atténuation donné de l'atmosphère, et la distance b) varie selon la luminance du fond. La distance a) est représentée par la portée optique météorologique (POM). 4, record 1, French, - visibilit%C3%A9
