I am hoping this is something that can be easily remedied, but for some reason when the weather is injected it affects the aircraft. If flying a small Cessna then the aircraft will sway around for a second or two. When flying the NGX, the thrust will suddenly increase before settling down again. All very peculiar. Help, as always, appreciated. 

I'm already guessing you have FSUIPC weather smoothing enabled,Howard?

I'm getting the same issue recently myself.

Sounds to me as though you are just experiencing the well known FSX wind shifts. Please read our SimForums explanation about this. You should just do the normal things to combat it. Start off by setting all weather defaults. Then set both the Adjust Options Automatically and Adjust Sim Friendly GRIB Data options. Make sure you always specify your Destination and Max Cruise Altitude, update the weather an fly. If you still experience 'problematic' wind shifts (a well know FSX bug when RW weather is injected) then try setting the Use Maximum Stabilisation option, finally you could set the Stabilised GRIB Data option. But the vast majority of systems will not need the last two stabilisation options.

FSUIPC4 smoothing will not combat this. It is due to internal bugs within the FSX code. Please read our SumForums topic on Wind Shifts and make sure you set the above recommended options to help bring stability to your FSX.

 

This is a very well known problem that will occur when you use RW varied weather without the above stabilisation options. It effects a few systems, most do not experience any problematic wind shifts especially when using the above options.

<p>Thanks for your speedy reply Stephen, appreciated. I'll follow your advice and see how things go. Cheers...</p>

<p>EDIT: Erm for some reason Stephen, when I make any changes to the weather download options eg. Disable update when below 2500' or tick download GRIB forecast, the changes are not saved. Any ideas?</p>

If you have  Adjust Options Automatically enabled then it will override other settings, in this case the GRIB data will be downloaded if your specified cruise altitude is above 6000 feet. Here is a diagram of the fields affected by the automatic settings,

Hi Cheryl, so if I tick 'adjust options automatically' to help with wind shift, as Stephen has suggested, then I do so knowing that any options I select will not be saved?

The easiest way is to enable the Adjust Options Automatically and Adjust Sim Friendly options and let the software automatically set the other highlighted options for you. if you still have problems then enable the Stabilised GRIB Data (this is not set by Adjust Options Automatically).

 

Alternatively if you wish to tweak the options yourself then you can do this by disabling Adjust Options Automatically, it is up to you.

Thanks Cheryl...

Any options you select will be saved as the current configuration. Having the options adjusted automatically by OPUS may negate any changes you make that fall with in the automatic category. (Sim friendly, wind stabilization, weather update on approach)
