UK Visibilty

Featured Replies

I seem to have the visibilty of 10.56SM showing on the tracker whilst flying in the UK and does not change as the weather changes, this does not happen whilst over the U.S. I have registered version of fsuipc set as default settings, and the max visibilty under the Active sky 2004 set to 30 miles. Is the visibilty shown on the tracker, what is at the reporting staion, perhaps this is what is confusing me, although I have moved about the UK and it does not seem to change.Perhaps I have something set wrong somewhere, but can't seem to sort this out, can anyone help out please. ThanksAnthony(UK)

Hi Anthony,Not sure what is happening, this is a first report... The vis shown is indeed as per the closest station set. This COULD vary depending on the active vis smoothing processes in effect, but it does not explain why it only happens in the UK for you.Does changing the language options in AR (to display Metric units) change the results?Anyone else with similar reports?I will investigate some more tonight as well... Thanks for any additional info!

>Hi Anthony,>>Does changing the language options in AR (to display Metric>units) change the results?I have the latest Beta installed.The language is set to US on the tracker/options. No vis changes made to fsuipc, as I said just the defaults. When I tried other things I was at EGTE, the vis was showin the 10.56SM, which seemed about right. I slewed to somewhere where the vis was a lot lower looking out the cockpit, still showed aoriund 10.xxSM.I made sure that I was over a reporting station that was shown on the tracker.I think I did try the other languages but I will try now and report back. I seem to remember that when the language was changed I was getting all 9s in the vis area.Anthony....http://www.reality-xp.com/community/nr/rsc/rxp-customer.jpg

DamianI have tried changing the language to metric and it showed 9999 all the time. I have some screen grabs for you to see what I mean.What email address do I send them to, so as you get them.Anthonyhttp://www.reality-xp.com/community/nr/rsc/rxp-customer.jpg

hi.9999 in european metars mean tha the visibility is 10miles OR more. if the actual visibility is MORE than 10 miles it will always say 9999.How about make aktivesky2004 to use a random visibility setting in those cases. I have NEVER gotten more than 20miles visibility with metars with 9999 in it. Here in Norway this is very unrealistic. we can have 60-90 nm vis on good clear days. 20 miles visibility in 9999-metars gives a ugly grey foggy wall and it looks as you're surrounded by servere bad weather.Jan Roar R

Hi Jan,Actually AS2004 goes one step further. We use temp/dew point figures to calculate the moisture and will adjust the maximum vis accordingly. A lower dew spread = lower visibility. Vis of 60sm+ is very common when there is a higher dew spread. There is also a random factor here but the moisture calc is more prominent.As to never getting more than 20sm, this shouldn't be the case... I regularly get 40-70SM vis in dry wx. Is the problem that the wx has been moist lately?
