Hello Captains, 

 

i´m a Pilot of our stunning PMDG T7 (-200LR and -300ER) and i´m using this aircraft together with Active Sky Next (the latest version). I´m really happy ASN but it´s strange that i get turbulences on EVERY apporach. It makes the approach more difficult and i get them even if it´s sunny etc. That is strange and i can´t believe that such a huge airplane like a 777-300ER is effected buy turbulences this way. 

Are there any options in the ASN settings i have to change, so it´s more realistic together with our 777? Maybe you have the perfect ASN settings for me (turbulence scale..)?!

 

I posted my experience in the ASN forum but HIFISIM told me that it is realistic and it´s possible that there really was turbulences in the area on every approach i did. Well, i don´t really believe this!

Turbulence has everything to do with wind currents. Sure, it's often associated with thunderstorms, but in the fall and winter, high winds can easily create turbulence.

Airplanes fly through air. Air disturbances cause turbulence. All airplanes will be affected by turbulence.

You not believing it doesn't make it less true, honestly. I could reject the idea that the earth revolves around the sun, but that doesn't make it false. It just kinda makes me look like I'm ignoring facts...

 

That being said, it might well be your settings. Post what you have and we can all have a look.

 

Remember that the FSX turbulence should be unchecked (off). ASN will still create turbulence of its own.

Hey Kyle, 

 

thank you for this reply. I´m gonna upload some  of my ASN settings (only the wind option etc, this is enough i think) but nearly every option are on "default". Yes, maybe ASN is hyper realistic, but sometimes i get pretty hard landings/touch downs, caused by the turbulences. For example: I´m on final and disengage the AP. Now i start to flare and everything looks good and smooth but suddely a turbulence appear and pushs me hard on the runway (-400ft touch down rate). 

 

Here are the settings (FSX turbulence setting is unchecked): 

 

Wind options (and effects)

- Maximum surface wind: Current setting 100 (default is 100)

- Maximum wind turbulence: Current setting 100 (default is 100)

- Turbulence effect scale: Current setting 70 (default is 70)

-Maximum wind shear: Current setting 50 (default is 50)

-Interlayer wind interpolation: True (default is True)

-Enhaced turbulence: False (default is False)

-Wake turbulence strength: 50 (default is 50)

-Maximum downdraft rate: Current setting 500 (default is 500)

-Maximum updraft/thermal rate: Current setting 500 (default is 500)

 

Maybe there is an option i have to change to get the best results with my T7! 

 

Greetings from Germany,

Maurice,

 

check your terrain and your AI traffic, because what you have experienced could easily be up- and downdraughts as well as wake turbulence.

 

If your heavy B777 follows a smaller aircraft on final, wake turbulence effects on the T7 will be rather little and could "feel" like some degree of turbulence.

 

The same goes for up- and downdraughts due to terrain features.

Maybe you´re right and i know this effects. But it´s strange that i never get "relaxed" approaches with active sky next. Nearly all approaches are very unsettled, even if the wind is calm. 

For a test, try a couple of airports surrounded by flat terrain and AI traffic settings (commercial and GA both) off.

 

Do you have thermals activated in the sim settings?

 

Also, do you use any "forth party addons" like Accufeel that introduce additional effects on aircraft?

Maybe start with ASN off and clear weather? If it happens there surely isnt ASN.. if it doesnt move on to things like you said Oliver

Was there an aircraft holding short?

 

For some reason, ActiveSky products don't interpret aircraft movement into wake turbulence very well. An aircraft sitting still on the side of the runway still gets wake turbulence generated, when in this real world, this is not true.

 

I turn the wake turbulence setting to zero for this reason.

 

That is likely the problem.

Okay, Kyle! So i´ll disable the wake turbulence, too. And what about the downdraft settings? Do you have the same Turbulence scale settings? 

'Tag Maurice,

 

as stated in the intro manual it is recommended to "Disable turbulence and thermal effects on aircraft" whithin FSX. Start with this if not already done. Also try adjusting the "Maximum wind turbulence" slider to a smaller value. Leaving it at 100% may be unrealistic.

No - it's just the wake turbulence that should do it. Check that first.

Sorry, I have too many years in the cockpit to accept any turbulence simulation in FSX.  All turbulence, up/dn drafts and whatever is turned off and I still use FSUIPC to limit wind velocity changes to 1 kt / 8 sec.  Yes, I do not simulate rough weather but neither does FSX or any add-on I've tried. I really like ASN and continue to use HiFi products, just this is something Microsoft got very wrong.

You don't agree with this from the ASN Users Guide Page 16?

 

"AS Connect has been tested to be compatible with all other modules including other low-level interface solutions such as FSUIPC. When ASN is run, it automatically installs the AS Connect module to the simulator (if not already installed). When the simulator runs, AS Connect is initialized prior to FSUIPC, so that low-level weather interfacing ability is granted to ASN exclusively. When using ASN, certain FSUIPC weather-related features (such as wind smoothing) will not function. ASN and AS Connect will instead completely provide all wx-related functionality including wind smoothing."

Thanks Michael, I missed that.  Regardless, all my turbulence is turned off and ASN does a good job of taming the FSX wind machine (LOL better than I realized).

Dan, after reading this thread http://forum.avsim.net/topic/387061-activesky-2012-settings-what-i-am-using-now-with-ngx/ and doing test flights I stopped using FSUIPC for wind smoothing.
