Turbulence

Featured Replies

First I would like to say how great asv6 is and thank all of the talented professionals for bringing this product to us and providing some of the best support around. I have some constructive criticism for you guys to ponder. :) One thing I have noticed about asv6 is that there is room for improvement as far as turbulence is concerned. For example when flying below the cloud tops on a day with broken clouds and no severe weather the air should feel rather smooth, but when approaching the clouds and passing thorough the altitude at which the cloud forms (not neccisarilly even going through the cloud) there should be a few light bumps depending on aircraft size. There should also be turbulence whenever passing through a cloud, an overcast cirrus layer should cause light turbulence, a severe t-storm should have a few shakes when passing through the cloud tops, and the middle of the cloud should have stronger turbulence and possibly up/downdrafts, as the clouds get bigger and more organised turbulence should be greater when passing through. One question I have always had was why is there a vas strength frequency in the options box. Shouldnt the vas strength be determined by wind speed and weather types? Also is vas simulated in t-storms, because the developmental stage and size of a t-storm should also determine the appearence and strength of up/downdrafts. Finally one last thing I have noticed and would really like to see improved is the high cirrus layer that may or may not extend miles from a thunderstorm, and usually light turbulence in an airliner accompaines this layer. See the screenshot for an example.Thanks for reading.

Hi Mike,Thanks for that!Can you do a copy and paste into an e-mail to [email protected]? We do keep track of all suggestions that way.Thanks!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/

Sure, E-mail sent. One thing I have always loved about this company is your positive professional attude and you are always open to suggestions and dont take it as personally as many other developers seem to, keep it up!

One other thing:Quote from Above:_______________________________________________________________________One question I have always had was why is there a vas strength frequency in the options box.

Hi Mike,The way I understand it, is that VAS covers the "clear" type conditions, based more on landforms. The turbulence factor is more for clouds/storms. As programmer, Damian would know more about the differences!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/

Hi,Thanks for the suggestions.VAS strength and frequency options are of secondary influence to the deemed weather conditions. In otherwords, in high winds, low air stability and mountainous terrain, even low frequency and strength will result in some decent up and downdrafts. Likewise, in stable air, calm winds and/or flat terrain, even high freq/strength will result in tame vertical air.The settings have the greatest direct influence in average conditions (normal terrain, normal wind, normal air stability).We are working on ways to make such settings more intuitive and flexible. We're of course also working on better turbulence modeling and we appreciate the feedback :)Best,

Thanks alot for your support and promt replys, one thing I love about you guys is that there are always updates, you dont forget about your product like most developers do. One question I had is what is the maximum altitude the a cloud or t-storm can tower up to, in real aviation they can tower to FL600+ in extream cases, in asv6 I rarely see them about FL330.Thanks for the support

Hi,Correct, the depiction limit in FS9 is about FL330. Those that go up that high are tremendous frame-rate killers, which is partly why we haven't attempted to make them bigger as of yet. We hope to bring bigger (both higher and horizontally larger) CB's including supercells in the near future :)Best,

Thats good to hear, hopefully it wont be too long then.;)

Hello again, I dont want to seem like a nag about this turbulence thing, but what is the recomended setting for the turbulence frequency. I have it set on 71. If I set it too much higher I get too much turbulence in clean air at fl350, but at this level I was flying through a thick layer of cumulous overcast at fl320 and it was waay to smooth, with that weather you should get a few decent jiggles. And also is convective turbulence modeled?
