Hi

 

Please download the latest beta 2.30 released today and try that first. If that does not get rid of the wind shifts then untick the Relax Wind Smoothing option (I see you have already done that). If your system is still plagued with wind shifts at higher altitudes then try setting the Transition altitude to 0 feet and adopting global surface winds. Let me know how you get on.

Ok just did a couple flights. One short hop flight had an instance of overspeed and height change but moderate. The 2 hour flight i had 3 of them and quite drastic. I will try the unticking of relax wind smoothing although I dont understand why i would want to not relax the wind smoothing. I had it on because that is your default.

 

Can you tell me if and where there is a log file so i can see the data that perhaps shows the changes?

And I suppose next if that fails would be the global wind changes and transition altitude of 0. I suppose that greatly reduces the realism?

Hi Dave

 

There isn't a log file. You do have to reduce realism to stop FSX misbehaving with wind shifts. The weather pdf has a section describing the settings to overcome wind shifts, and yes you have to move towards global winds.

Hi Dave

 

Use beta 2.30.2 posted today the upper wind targets are more in tune with the wacky behaviour of FSX. First try it with surface wind smoothing relaxed (the default with 15 + 15 set), then if you experience wind shifts try more wind smoothing (option unticked, or try 10 + 10 setting), if you still experience wind shifts without any relaxation, then i'm afraid your only recourse is to set the Transition and Recovery altitudes and use wind stabilisation. Not many people need to use these options. We do not experience any shifts with the new beta on any of our systems. But some systems are more susceptible than others. The latest beta helps.

 

Wind smoothing is relaxed by default to ensure maximum compliance with METARs. So you increase the surface wind smoothing and if necessary enable wind stabilisation only if your system needs it.

 

But it is still better than using completely global weather ! At least you are only needing to control the surface winds and if you are lucky the system will recover your real surface winds as you descend below the Recovery altitude (the future weather smoothing may recover more often). All complaints to Mr Bill Gates please.

And my system also have 4 Gb RAM and I got interested in OpusFSX since it appear better then both AS2012 REXE.

Is the amount of RAM the only problem and what is the problem?

In my experience, OpusFSX offers the best performance of the above mentioned two.

Thank you. I will download and try it all out. Just confused on one thing. What does "some systems are more susceptible than others" mean? Its the same core flight simulation program. Same weather engine. How would my system be any different from yours other than hardware? I fly with FSX and P3D and im certain you fly with the same. So how is it that you barely see these symtoms? If yours is barely noticeable I would like to mimic yours then. Just a thought if we are running the same software. (windows 7 64 btw)

Flying in Antarctic area I have noticed that OpusFSX incorrectly creates dynamic weather based on closest METARs available. Let me illustrate:

 

I am on the location of Patriot Hills (airfield code: SCPZ). Runway is ice/snow. I am at about 2800 feet ASL. Antarctic summer. Time - 0350Z. Here's what the spy window shows:

If you look at generated temperature component, which is +10C it becomes clear this is not Antarctica. The closest METARs by location show current temperatures -39C and -16C.

 

Stephen, any chance you could add some coordinate based variable to the program weather calculation engine to ensure we get plausible temperatures in Arctic and Antarctic locations?

 

Thanks

I it is reading metar from NZWN that is Wellington, capital of NZ, way too far from where you were flying.

It might be useful for OpusFSX to provide a distance to the METARs it is using.

You might need to try Vatsim weather option maybe ?
