I keep running into this strange weather situation and was wondering if anyone else has it. A lot of times I'll be cruising along and all of a sudden my airspeed decreases 10-15 sometimes 20 knots and I have to pitch up the airplane to maintain altitude. Eventually it goes away, and the airplane starts climbing so I pitch down and I go back to my original cruise speed. Does anyone know what this is? Its like hitting a pocket of air or something.

It's been with us a LOOOOOONG time, and it's referred to by many as...Abrupt Changes in Winds AloftTry flying with Real World weather at a high altitude somewhat near the aircrafts airframe speed limit, especially with an aircraft that has highly tweaked for realistic flight dynamics, and tell me what happens.Pete Dawson fixed this problem in FS2002 with FSUPIC. Now he fixed it again(somewhat at least) for FS2004, but it took him a much longer time to be able to come up with the fix for FS2004 than it did for FS2002. To use the fix avaiable in FSUIPC you might have to have the 'registered' version FSUIPC, I'm not sure. I have the registered version though and here is where you enable it...FS Menu --> Modules --> FSUIPC --> Winds Tab --> Smoothing --> Check the bullet labeled 'Smooth wind changes near aircraft with changes limited to this many knots or degrees per second'I have been thinking about asking if this has been fixed for FSX or whether we will have to depend on Pete Dowson again. I think I will go ahead and ask in the FSX forum now.Hope that helps

And if you have the free version of FSUIPC it is hard coded to 5deg/sec and 5mph/sec.Hope this helps,Jimhttp://www.hifisim.com/Active Sky V6 Development Team Active Sky V6 Proud SupporterHiFi Beta TeamRadar Contact Supporter: http://www.jdtllc.com/AirSource Member: http://www.air-source.us/FSEconomy Member:http://www.fseconomy.com/
