To everyone who is having issues with ASA and the MD-11 PMDG getting random airspeed spikes, I do not have this issue. I used to with ASX and the first release of ASA. But after some tweaking of the ASA settings, the airspeed and altitude spikes went away. Everything is smooth sailing so far. When you are using ASA as your primary weather engine, you need to consider what settings you have. Yes, every single one of them can have a major impact on how FSX responds. I would also suggest to anyone who has ASA to make sure you get Service Pack 1 to ensure you have the latest fixes.Here are some settings to consider with ASA to get a handle on the wind spikes:General Options:Dynamic Rate of Change - Towards a lower percentage, mine is set to 30%Cloud Options:Minimum & Maximum Cloud Turbulence - Never take your Maximum anywhere near 100% as you will get some really terrible spikes. I have my minimum set for 0% and the Maximum set for 25%. This lowers the intensity at which Turbulence will affect the aircraft model. ASA seems to amplify the affects of turbulence a little too much during the simulation.Wind Options:Enable Direct Wind Control & Smoothing - Checked. This is especially important when looking for correct wind changes and no sudden spikes.Wake Turbulence Strength - 25% or close to thisMinimum & Maximum Wind Turbulence - This is the same as the cloud turbulence, 0% and 25%. No more or your going to get unrealistic amounts of micro bursts, which is basically what you guys experience, :( .Minimum & Maximum Wind Shear - 0% and 25%, respectively.Automatic Thermal Generation - 25%Terrain Based Up & Downdraft Generation - 25%Maximum Downdraft Rate - 50 fpm appx. This is VERY important to get rid of the annoying altitude changes.Maximum Updraft Rate/Thermal Rate - 50 fpm appx. VERY ImportantVisibility Options:This section isn't that big of a deal, however, I recommend you check Disable Haze Layer and Enable Visibility Graduation and Smoothing.Remember to click the green "Save and Apply" button at the bottom right of the ASA screen.That pretty well covers the settings to where you will want them to be to get rid of the sudden airspeed and altitude spikes associated with the PMDG MD-11 and ASA. This will also help any other addon aircraft you have with ASA. Once again, these settings work best for me and I enjoy smooth, but correct turbulence simulation. Some settings may need to be changed depending upon your own liking and what bests suits your flight sim configuration.Hope this helps!CapP,As far as importing the winds aloft into FSBuild, are you referring to ASA or the REX Weather Engine? I get winds aloft from ASA with no problem in all of my flight plans in FSBuild.
