Copied Jim, I'll try setting it at 50%, like the default value is, I guess? I'll tell you tomorrow the results.ThanksFede

Hi Jim, I didn't have enough time for a full flight today, but made a couple of attempts, and they went fine. Same way, departing EGLL northbound, I looked at the wx stations which weren't depicted initially, and then after about 15 minutes loked again and they were written correctly (I didn't check the clouds, but they were usually ok). Then I checked FSUIPC log, perfect. I had no other programs running but ASA. Tried with change sliders at 50, then lowered at 20%. Both seem ok. I'll tell you when I make I complete flight. I hope this is the one :)CheersFede

I've thought about that. My theory is that it is related to those 30 second phase-in times being specified by ASA when it is setting the WX station weather. You'll remember than when it is set via FSUIPC no delay is specified (0 seconds), and that way worked.What I think is happening is that at the zero rate of change, the phase-in of the new WX weather over 30 seconds either isn't happening at all or it is slowed down proportionately so long that it may as well not have been set. In other words, the "30 seconds" is only 30 seconds at either the full rate of change, or possibly any non-zero rate of change (a case for experimentation there, perhaps).This being the case I think it would be a good idea for ASA to set the minimum rate of change slider such that it can never be set so low that the 30 second phase-in causes these non-weather symptoms -- or alternatively, at very low rates of change also set the Seconds phase-in delay to zero or at least very low. No doubt this is also why the specific problem of fixed weather doesn't affect many folks -- me included. I've never set the slider in ASA at all, and normally have it half-way in FSX. But I may now try it much higher, to see if that gets rid of the weird temperature and pressure anomalies I have experienced.RegardsPete

Hi Jim, after 5 flights I am very very glad to say it works! The wx change set at 50% made the trick perfectly. Now I see depicted exactly what ASA's report screen says, everything's fine. I also turned force high priority process on, to make it quicker, updates every 15 minutes. More technically, in simconnect log the wx seconds is still at 30, maybe you should follow Pete's advice and set it at 0 secs, in the next beta build.I noticed one small problem, it sometimes happens I open ASA, it does what it has to, but I have all interpolated stations, it seems there is no actual report. It happened in big airports like EGLL, KRDU, KLGA and some others. I just close ASA, restart it after 1 second, and the wx reports appear, no more interpolated but actual. Strange. As I said, small bug. ;)Pete, Jim, thanks again for your help. I would suggest everyone who's having these kind of troubles (wx not updating, wx different from report, stuck cruise winds, etc) to set the wx rate of change at 50% (maybe even more, I haven't tried). It solved the problems to me.CheersFedeP.S. I haven't used a flight plan in ASA, so it really didn't know where I was going! :)

Hi, Same for me I have to restart ASA too....I have ASA435 with FS9.Christian

Yeah, sorry. I'm in FSX ASA SP1 B433. I think it's not FS9/FSX related this one, but maybe I'm wrong.Fede
