Judging Visibilty at minima MDA/DA?

thanks for the thought.


I understand, its all up to pilot discretion what is indeed for e.g "4.2 km"


I get to the minima make my own decision as to wether it "is or is not" and go from there..


I can use the atis or awis to build a "mental picture" as what to expect but cannot use it as a hard and fast 'yes or no'


or put another way, other than RVR and pilot discretion. is there any other method that is 100% stand up in court??




Hope this makes sense.
