Problem on approach

[Crocet]

Dear all, I have been doing some research on 'bounches aircraft' problem. Its explained that it happend because of switching to exterior view and or
aircraft.cfg, it also explained that happen during taxiing, at the runways and gate.

I have the some problem but during the approach just about 100 feet above the runway and I did not switch to exterior view. I am not sure if my
problem can be categorized as the same problem as 'bounches aircraft at the gate'. I have been doing some research on the forum but I could not find
the answer to this. And the funny thing is it only happen when I am having FsP active. I do have some payware airport scenery but this bounching also
happen on default FS9 airport.

At the moment I am flying with A340-500/600 from CLS. If this problem can be categorized as the same problem as 'bounching at the gate'? then I will
contact CLS to ask for a solution. If some one has the same experience please share it with me and if someone can give me a little explanation.

Best Regards

As far as I have heard, this problem appears to be related to the footprint of the aircraft... for instance, POSKY aircraft which have
sophisticated 12 point footprint are prone to this jumping up and down. I believe there are rem-ed sections of aircraft.cfg, which define
default three point footprint and I suppose you can switch to default footprint if you un-rem those sections and rem the sections with multy-
point footprint.
I haven't tried this myself yet, though, so I might be mistaken. If anyone has any experience concerning this bouncing, please come up my
frequency.

One thing I forgot to mention. Eventough my aircraft bounches somehow it didnot have any effect with the G force (still within normal +1/+1,1) So my
pax never complain about the flight.

You mean bouncing while still in the air? Can it be wake turbulence? Do you have Active Sky?

[Crocet]

Yes, bounches while in the air, I do have Active sky but not sure about the wake turbulance. Can you explain that to me? What sort of things that can
influence this wake turbulance etc.

Any aircraft will generate turbulences (vortexes) at various points but most dominantly over the wings and at the wingtips.
These turbulences are like horizontal cones following the aircraft - much like a horizontal tornado.

When you follow an aircraft on an approach you will sooner or later enter these wake turbulances.
Depending on the size of your aircraft in relation to the aircraft producing the turbulance this can have a disastrous efffect.
They can lift one wing or push it down - in short - you can loose control very easily.
There is an excellent manual for all of you wanting to dig a little deeper into the matter =>

In Active Sky there are two settings that influence this behaviour - you will find them under options
1.Wake turbulence simulation (you may want to turn it off when you experience problems landing)
2.Increased wake effects (only reccomended for experienced pilots)

General rule of thumb - the smaller the aircraft you fly the less wake effects you want unless you are in for a challenge.

Hope this helps

Thanks for all the answers. I will give it a go (diasble the wake turbulence in Active sky) and see what happen. If the bounches still appear then I
might have a problem with my FS9

Once again thanks a lot.
