The metar realwx controller checks every 60 seconds for a station reporting metar and loads that data if the station id has changed since the last check. It also rechecks the metar every 15 minutes for the unchanged station. > > The context of this question is that I have the impression that if I would > fly transatlantic (I have never tried, since I don't like the ocean view > so much...) the METAR string would not change for a long time, and hence > the weather would not change. That's not very realistic. Without checking our navdata, I am certain there are not so many metar reporting airports in the atlantic, so you will probably live with the same report for a very long time. > > [..] > > To think this through, I'd like to understand how the weather fetching > works - does it always pick the nearest station, even if that is 3000 > miles away, or is there a distance cut, or some other criterion? There is a distance cut, historically set to 10,000 miles.
FWIW, there is now support to fetch a metar report for an arbitrary station by writing the station-id to /environment/metar[n]/station-id See $FGDATA/Environment/environment.xml for details.
