If I build a short flight, less than 200 miles from departure to destination, and load a flight plan in AS2004(patched), FS9 depicts my departure weather exactly the same as my arrival weather, even though the two metars are different. It looks like AS2004(patched) is telling FS9, via FSUIPC, to make my departure weather the same as my arrival weather. If I don't load a flight plan, the departure weather is depicted correctly.Is this to be expected on a flight of less than 200 miles?

Hi there,Sounds like you are experiencing the effect of GLOBAL WRITES.If your departure airport is not near an FS9 weather station, then GLOBAL weather will be depicted. Global weather is set to the closest station weather on first write (without flightplan loaded) or the destination station weather (with flightplan loaded).This would not matter if you were within 200nm or outside 3000nm. The only thing that is FORCED when within 200nm of destination is the winds aloft (if route based wind smoothing is enabled)."If I don't load a flight plan, the departure weather is depicted correctly."Can you illustrate this? What is your departure weather METAR, and can you confirm you are within 2NM of this station? If you are outside 2nm, variances are normal and expected, and FS9's own interpolation routines can greatly effect this . If you would rather not have GLOBAL weather set, and stick strictly to reporting station zone weather (and FS9 interpolation) you can disable global writes. This can yield better results in areas with few reporting stations.Damian ClarkHiFi Simulation SoftwareDeveloper of ActiveSkyhttp://www.hifisim.comhttp://www.hifisim.com/images/as2004betateam.jpg

Damian,I was at a reporting station airport, at least that is what the FS9 custom weather map showed. I'll check this all out again and send you related files if I can recreate the scenario.By the way I just completed probably the best flight I've ever experienced in FS9 thanks to AS2004. Departed KDPG in Utah in 2mi vis conditions, broke out over a solid cumulus overcast depicted nicely below. I was cleared on up to flight level 240 and flew over the overcast cumulus for quite some distance. I then flew into clearing conditions as I headed toward my destination KBOI (boise, Idaho. Higher overcast cumulus slowly built up again on the horizon as I approached Boise. I flew into the clouds as ATC (Radar Contact)began my initial vectoring into Boise. On final, I broke out of the clouds into a 1 mile visibility condition in snow and made a mimimums approach landing. No sudden clouds, no violent wind shears, and a fairly nice transition to low visibility conditions. Nice job on AS2004 and the latest patch.

I just sent you an e-mail with info on a short FS9 flight to set up and an AS2004 weather file to go along with it, to illustrate the changing departure weather conditions I see when I import a flight plan into AS2004. This is happening at FS9 weather reporting station fields, so if its got something to do with global writes, it is strange that it affects reporting station weather.
