You are possibly all talking bollox chasps ... it is in all likelihood our old friend the Bituminous Runway or Oil Treated Runway or a similar type of Taxiway or Apron surface that can be present in many AFCADs back to haunt us from our FS9/FSX days.

 

This surface is still selectable by scenery designers in LMs P3D & will also be apparent if you port across scenery from FSX to use in P3D & it has been used by the scenery designer, it may also be present by default in some native P3D scenery that has been ported across from FSX ( that have not been able to fix everything just yet!)

 

For some reason since FS9 days PMDG products don't really like these type of surfaces.

 

I found an excellent freeware AFCAD for LIRA Rome Ciampino (FSX) the other day & after fixing the PAPI, NAVAID, RWY Lighting & Marker harmonics (they are NEVER right - even with most quality payware save FSDT) I forgot to fdo a final check of the RWY surface with ScruffyDuck Software's excellent ADE programme.

 

Lo! earlier this evening on the way in from Athens in the NGX I had an ... ahem ... very interesting roll out down the runway as it was still a Bituminous Runway !

 

Your simply looking too far into the woods for something that in reality is staring you in the face.

It's this what I just said a few posts back, although it seems to have gone unnoticed by the fellow who was having issues?

 

If the taxiways are tagged with the wrong surface materials you'll get a bumpy ride when you taxi.

 

One other thing that can cause it is if the runway/taxiway in the AFCAD is not tagged with the correct surface. Once time I updated Geneva by FSDT and experienced the bumping while taxiing. It turned out the taxiways were tagged as gravel and not asphalt or concrete and that was what caused the bouncy taxing. One I changed the taxiway materials using ADEX to concrete the bouncy ride went away.

 

Just some things to consider.

What I'm seeing isn't caused by the scenery or how the taxiways have been defined because I'm only seeing this in P3D but not in FSX using the very same scenery.

I think Sean has identified your problem as the taxiways not being flagged correctly and will need to be recompiled manually with the newer version of ADEX version 1.60 or higher to set the flags. Read the quote below from FsDev.

 

Read the full link below and you will gain a better understanding of why the FSX version of your airport works fine and the P3D is bumpy.

"Why would you want to do it for all of them? The stock airports have the flags set correctly. The problem arises with airports created with ADE prior to the introduction of P3D v2. Before that version FS did not honor those flags so it did not matter what they were set at. ADE set them to false in older versions by default and it did not matter. It matters now only for P3D v2 and later. As far as I know the vast majority of stock airports in P3D v2 are fine so you would be wasting time processing them."

Ah, now I'm with you!

 

Well, since I don't really care about this effect I'll just leave it as is but thanks anyway for the explanation.

Bumpy runways have always been the bane of FSX. Someone, a long time ago, decided in an inspired wave of ill-considered thought, that some regional airfields, and many grass runways, ought to have uniform ridges neatly placed every 10 feet or so, so they "emulate" less than smooth surfaces. They emulate nothing except a ridiculous bucking bronco ride.The problem is they are hard coded into the Afcads or runway designators and there is little you can do other than recompile all such runways and taxiways to be bucking bronco free. They are, and were, always a completely stupid idea and just create a nightmare for any sim aircraft suspension designer.

 

This comes close to yet another wonderful feature of FSX where another bright spark decided that you couldn't turn aircraft lights on until it gets dark. 

 

Somehow these two ludicrous concepts got through a committee stage circa 2005!

Glad you understand the issue now and thanks to Jim Burke for posting that link. I probably should have posted that info originally to help you understand better. As Jim mentioned, using ADEX to recompile the ADE files is not to much of a hassle to get you a smooth ride again. If you just do a few at a time before you fly, you'll have your whole collection on airports fixed rather quickly.

Thanks Sean, I'll consider that.

You don't have to buy ADEX when the free ADE from Scruffy Duck will do the job and they provide a button that selects and sets all paths.  I have both applications and prefer ADE for most AFCAD chores.

That's a great tip, thanks!

Dan, ADE and ADEX are the same thing and are both free, which is why I recommended it.

 

I think your thinking of AFX by Flight1 which is a payware AFCAD editor, but ADE or ADEX which is what it's sometimes referred to as, is free.

 

Sorry for the confusion by calling ADE, ADEX which is the same thing. Sometime ago I thought they added the X to the end of it.

 

Sean Campbell

Thanks Sean for the clarification.  I was thinking of AFX, and yes the latest is ADEX for both FSX and P3D.  The name change confused me, happens when you get old.

Thanks for the HU Sean.

Waking up this thread again as I've now reached a state where I'm gotten tired of this bouncing effect so thought I would give it a try to fix the issue using ADEX.

 

Read the full thread over at FSDevelopers and also another thread linked from that thread but failed to find any information on how to fix payware airports such as Aerosoft Stockholm-Arlanda.

 

The instructions I found only mentioned how you would open a "project" and then click a button resetting all the flags to their default values but how would I do this for a payware airport where I don't have any project file to open? Or maybe I create a new project file by opening the payware airport in question and reset all the flags and then recompile/save the project somehow resulting in a fixed payware airport?

 

Sorry for sounding like a complete newbie but that's because that's exactly what I am when it comes to this :wink:

 

Maybe there's some kind of guide or tutorial how to fix payware airports using this tool, will look into it tomorrow.

Interested in how to fix this too.  I have the same issues at Aerosoft's ESSA in P3D 2.5.
