"Well, it certainly wouldn't always be realistic in my part of Northern Europe! Wink A visibility of 30 miles is certainly quite common, once you get above the murk". . . you clearly don't live in Devon then :D .
Thanks for your swift reply Peter. I didn't think of reading the documentation. . . . . why ever not!!? duh! :? I will indeed. My assumption has been that, if there is vis control like the sort I'm looking for, it would only be with a registered version of FSUIPC :D
What I want to do is achieve a situation where visibility can be anything from 0 to about 30 miles. The way I've dealt with it is to set my own weather parameters which always includes a 30 mile vis. Not ideal but at least it avoids that dreaded thing.
Anything more than 30 miles in FS looks unrealistic to me. Anything more and that 'distance haze' you get even on a clear day is missing. That is on the ground. Of course at altitude the situation is different as you point out but that sudden shift to unlimited vis after climbing through a limited vis is the thing I hate.
