I'm was flying an Antonov AN-32 on final into Tampa Int'l. The tower cleared me shortly before. I'm lined up nicely, flaps employed, cutting back the throttle . . . and then suddenly I'm in a barrel roll with no control whatsoever.I did manage to obtain control after the roll and greased the landing!Anyone else have that happen to them? Was that suppose to be jet turbulance? (no jet ahead of me that I could see)

If you have ASA, ASE, or Active Sky installed there is an option called wake turbulence that if ticked could cause this if an a/c is taking off, passing you, or landing near where you are. In ASE you can disable it or turn the slider down to minimize the effect. In the other weather addon it maybe possible to either disable it or tone it down as well.

Thanks, I hadn't thought of that. I do indeed have ASE.

That is indeed what happens from ASE induced wake turbulence. Congratulations on the landing.

Hmmm....so it's ASE causing the problem, eh? Now let's see the kind of model you're using. If the AN-32's rudder is too effective, it becomes sensitive with turbulence.

Funny I had the same thing happen on final to KFLL in a 742. 5 miles out I banked 45+ degrees to the right. Had to do a missed approach though. There was no room to recover and make a good landing. This was about 1130 GMT. Yes ASE also here but my WT is set to 100% so I can't complain. :-)

No, ASE is not causing a problem here. ASE is modeling what happens in the real world. You may need to think about increasing the separation between yourself and the aircraft ahead of you, or taking other steps as necessary in order to not intrude upon a correctly modeled wake turbulence effect.

Exactly. Don't blame ASE, which provides an option to turn off wake effect if you don't want real world conditions.

It was a good lesson on many levels--I didn't know wake turbulence could be that powerful (assuming it is indeed being modeled correctly by ASE), I leaarned about a new setting in ASE, and I am a more aware flightsimming pilot now!Thanks.

It is certainly pokey and can hang around for a while. IIRC when I was flying GA here in OZ the figure for a light aircraft movement waiting after a heavy aircraft movement was 15 minutes. Thank goodness FSX ATC doesn't simulate that. :(

Yes, wake turbulence can be extremely powerful. That's why commercial jets are supposed to maintain a one minute separation for T/O and landing. I think that has been reduced somewhat at busier airports. If you ask me, it's a case of pushing the envelope almost too far. And guess who will get blamed if an airplane crashes, not the tower operator I'm betting.In the flight sim world I took off about two minutes behind a commercial jet-I forget which it was but not a heavy--the turbulence was still there, but reasonably attenuated. Still kind of a twitchy take off though.

I also experienced this a couple of times.How long does this last with ASE (WT effect)?

I'd also be interested to know how long it lasts. In my case there were no aircraft ahead of me that I knew of--certainly none visable. Perhaps this needs to be brught up on the Hi-Fi board.

The wake turbulence from the a/c you don 't see is the one that might kill you. Depending on weather conditions, IRL, the effect can last for quite a while. The 15 minute caution is normal but there have been occasions when WT was hanging around for much longer. It really depends on the prevailing weather pattern as to how soon it will dissipate.

Pretty surprized that one WT event posting can go on and on, LONG after the event is over. :( :(Durations depend on the the plane and WT Strength slider setting. Also, planes next to you generate more WT than those in front of you.
