These problems seem to crop up quite a bit throughout these forums: "My aircraft will not follow the LNAV path" "My aircraft suddenly turns and I cant stop it" and "My aircraft suddenly starts 'S' turning and no matter what I try I cant stop it"

 

Well 99.9% of the time this is because of an improperly configured weather set up coupled with FSX's poor depiction of wind turbulance. I used to be a victim of this extremely annoying problem and thought it would be nice to put some of you guys out of your misery too.

 

How you tackle the problem depends on the following:

 

Are you using FSX default weather engine?

or

Are you using a weather program like AS2012, ASX or ASE

 

If you are using FSX default weather your solution is to use the wind and pressure smoothing features in FSUIPC (if you have a purchased copy) or turning off wind effects all together within the engine itself.

 

Confusingly, If you are using a program like Activesky you need to turn off all FSUIPC wind and pressure smoothing options (as they conflict with each other causing wind anomalies) and let AS2012 take care of it, maybe even dampening down the wind turbulance setting within the program if needed.

 

Hope this helps and Good Luck!

I think a lot of the fixes just happen when one installs the latest FSUIPC, leave active sky as is.
