Hi there. I just did a flight from GRU-BGI and in the first 3hrs of the flight i ran into some heavy turbulence and thunderstorms. I tried tried to change course to avoid the avil shape clouds and all of a sudden i start to lose airspeed. I was cruising at FL340 @ mach 0.78 and loss airspeed down to 0.66 with a 10 degree nose up pitch, #####. The winds were not strong and didn't even had headwinds. I know some others encountered this weird phenomenon but how do i fix it. Another thing too, the aircraft banked to the right more than 45 degrees out of limits and crash.I seems to happen to anyone with Activesky and is the first time for it to happen to me . I know some said that if you have AS you must engage wind smoothing control but i already have that on. what do i do? please help!

reads like a wind shift and velocity change. FS has a fault in how it models wind changes. you state you are using AS ... which one? i'm using 6.5 and have no problems with wind shifts. do you have AS configured to smooth changes in wind?

down to 0.66 with a 10 degree nose up pitch

to be expected at such a low IAS at FL340.

... #####.

why the profanity? :( :( --

using AS 6.5wtf: What's the forcast?! haha. but anyway seriously. what's causing it. As i said before, there is a box i AS saying "FSUIPC Wind Smoothing Control", i have that check, now what?

what's causing it [iAS loss]. As i said before, there is a box i AS saying "FSUIPC Wind Smoothing Control", i have that check, now [what?/quote]even FSUIPC isn't perfect across a significant wind velocity/direction change. download weather reports by zones. AS improves on this by collecting a greater number of data stations and creating a average. faults still can happen if there is a significant real-world wind change; or bad data from the reporting station.AS support forum if you have continued problems -http://forums1.avsim.net/index.php?showforum=171--

I have AS 6.5 and experienced the exact "incident" described above just this afternoon approaching Sydney. I was passing very close to those anvil shaped clouds. The aircraft pitched down very violently after which I went manual and recovered without a problem.This is the second time I've had this, the first being in the Aeroworx B200. Frankly, I think this is a plus if it's simulated intentionnally by Active Sky and it had nothing to do with wind shifts. You don't fly close to storm cells in real life either, crews deviate by at least 20NM from them.The only problem in FS is that most aircraft don't have accurate wx radars so you can't really "see" them other than visually. :(

Download the Active Sky Enhanced manual from hifi sim. While you don't have that version there is a section in there about modifying PMDG and FS9.cfg and other aircraft that they claim are oversensitive to turbulence.Also be sure your FSUIPC 3 is current from here:http://www.schiratti.com/dowson.htmlIf you are following other large aircraft if you have wake turbulence enabled that can be a rough ride.Sometimes it is necessary to disable AT and AP in turbulence. A sudden loss in altitude will cause the aircraft to pitch up with slows the IAS. With the slow reaction of turbine engines as AT commands a thrust increase it may not be enough to prevent a stall.

Thanks alot Ronzie!! Working on it now by editing the FSUIPC from the AS manual.

yea. It's a weird problem but i took ronzie's advice in his post to this topic and everything should be rectified for you, me and other simmers who have experienced this problem. I will take your advice, howver,which i already knew to fly at least 20nm from TS activity. Take a look at this, http://www.hifisim.com/ASEUserHome/Documentation/ASE.pdf. The link may not be intended for AS 6.5 but works actually. Thanks!!

Hi again ronzie. I was reading the manual and it said to edit the fsuipc.ini which is located in the modules folder. It said edit settings : TurbulenceRate=0.5,2.5 TurbulenceDivisor=40,40,80,80 But when i check the folder with anything listed as Turbulence it wasn't there to be edited. I thought the ini would have "TurbulenceRate and TurbulenceDivisor" listed only for numbers to be changed. By any chance, are these supposed to be "new" entries into the .ini rather than the manual mentioning "edit". I see nothing along the lines of Turbulence in the .ini i have. Or, are they more INIs? You tell me.

Could also be that icing bug (fs9), that some experience from time to time. I read it had never been eradicated completely even by the settings in FSUIPC.Dirk.

Could also be that icing bug (fs9),

at first read of the OP that comes to mind ... bu the speed loss if over time, not KIAS going zero.--
