I must say that I felt in love with the software since the begining. However, why is the program making the ATC to cancel AI's IFR at all times?The barometric pressure is changing all the time which in effect ATC tells AI that their altitude is too high or too low from the assigned altitude. It shouldn't do that. Plus there's a problem with changed wind direction by the airports, I was on final to KDFW and the wind direction changed and the ATC told me that I'm cleared to land on rwy 17L instead of 35L as it was originally? I've tried to change options in the FSUIPC but it didn't help.Also, why is the software downloading wind alofts when I unchecked it in the option menu?Thanks in advance for any help I can get on this.

Hi, your baro smoothing option (FSUIPC, Technical tab) is not enabled, or is not set slow enough. Please refer to the documentation (Setting up FSUIPC) for pictures of the screens to show you how all the settings should be.

Damian,Is this correction going to change ATC's behavior to change departure and arrival runways?

No it will not effect ATC at all for runways... ATC is only concerned with the WINDS so just make sure you are using your destination force option to make sure you get consistent winds for your approach and ATC vectors.

Hi! It's not WXRE that cancels IFR flight plans, it's 2k2. For some reason that I can't explain you're supposed to adjust your altitude as per pressure and not stick to your flight level...

Hi this is another issue actually not related to AI aircraft losing their IFR clearance (but YOU losing it).It has to do with the fact that the FS ATC engine doesn't account for baro pressure, so when the baro pressure is over ~300ft altitude (.30 inches) from standard 29.92 then this will happen, and you are correct, setting your baro pressure in this case will fix it. I will add support for "max baro variation" but this affects realism as well, so you can enable it at your preference.

Hey Damian,Thanks for all your help. Now that I have all this figured out I think that this software rocks!Btw, I've read in some other post that you are working on the update, I was wondering if you could make an option for the program not to download and implement the wind alofts in the sim? I know this would be a bit unrealistic but this option wouldn't hurt.Thanks for all your help!
