Crashing into invisible walls during takeoff/approach

Recommended Posts

Has anyone had this kind of problem?

 

I noticed it taking off from one runway at Midway (I forget the runway, but it was facing the Chicago skyline), and when on approach to 7L at Daytona Beach.

 

Even though I'm well above the tree line and other autogen elements, I every so often "crash" into what I assume is an invisible wall protruding upwards from those objects.

 

I don't remember it being so pronounced with FSX.

A simple solution I adopted years ago is simply disable crash detection, which I much prefer for many reasons, including this one.  I don't run into these objects often, but have in the past (both stock and 3rd party scenery), and it's frustrating and kills a good flight.  Additionally, turbulence/speed etc all have similar limitations that annoy me randomly.  When I crash, I know it, plain and simple.   That's good enough for me, I don't need the sim artificially trying to decide.

 

Not much help, but I would hit these in both FSX and P3D randomly... at least now I keep flying ha.

I agree crash detection is a joke, but sometimes it's nice to have when you want to know if you just made an especially hard landing or a crash landing. Especially since I use Prepar3d in conjunction with FSPassengers (mostly for airliners), and I'd like for there to be the negative consequences associated with having an actual crash.

 

Might changing mesh resolution help at all? Or maybe there is some way to ignore object collisions by editing a config file?

Nope - unless you know the EXACT object you either have CD on or off. The problem is in tracking down exactly what you hit. Finding something invisible makes it difficult.

Hi RioPilot,

 

Had same problem some time ago with airports at sea level (LICJ in Italy and PHKO in Hawaii).

Moving mesh resolution one notch to the left solved the issue in my case. At least til far.

 

Hope this may help, Cheers.

I'll agree with be77solo.  Crash detection gets you little more than headaches.  Better to learn to tell if it's a good landing by watching and seeing if you're satisfied.

Update: recently had that problem again landing with a PMDG 777 at LIEE (ILS 32). Repeatable crash at RWY edge, flaring at 100ft, til I move mesh resolution slider to 10m (so two notches to the left). After that, no more crashes. Wonder if anybody else's experiencing same issues with default airports, especially at sea level with PMDG big birds.

 

Cheers,

 

P.S. still on P3D V3.2 BTW

I had this issue with FSDG's Seychelles X published by Aerosoft. Always crashing about 30 ft above the runway. Hugely frustrating after a 5 hour flight across the ocean! Never noticed it in the FSX installer but it was definitely an issue in updated installer provided for P3Dv3. They released a patch/fix for this particular issue but I only became aware of the patch by Googling. Now all is good again.

 

If the problem exists with payware airports, let the developers know over on their websites/forums and hopefully they will issue a fix. For standard P3D airports, let the folk here know which ones you are having a problem with specifically and someone might be willing to test their system to see if they also crash. At least you will confirm that it is not a specific problem with your setup. As noted, the terrain mesh slider can have a bearing on this.

 

Not sure if it does have this crash effect, but also check that your FTX regions are set correctly in the FTX control panel as it definitely has an effect on elevations. If I fly outside an FTX area with just Global and Vector, but forget to make that the active setting, (in other words, stil set to FTX NA PNW for example) you do notice elevation issues at many airports including standard ones.

Thanks glutcheon,

 

Actually I do not have any FTX region installed, only FTX Trees HD: do you know if this may affect somehow stock airports elevations (i.e. particular recommended settings in FTX Central, if any)?

Haven't you turned crash detection off?

I was having a specific issue where the entire P3D sim would crash (as in crash to desktop aka CTD) if I crashed an aircraft with detect crashes enabled. Oddly, by having the sim rebuild my prepar3d.cfg file yesterday, I seem to have fixed the issue as I have bent several aeroplanes in the past few hours trying to replicate this and no CTD's. So that issue (touch wood, hope it really was that easy!) is gone. The second issue I have with enabling crashes is that the sim reloads you in the cockpit of the default flight scenario, whether you like it or not, after a crash which can be more than a little annoying to me.

 

So yeah, kind of in between at the moment on turning crash detection off. I like to keep it real and for the most part I fly "seriously" (seriously :wink:) and do not go around crashing, so I also like it that there are "consequences" if I fluff a landing. The jury is still out on this one in my mind....

Hi Bob,

 

Yes indeed, but my FSPassengers...passengers  :smile: are not very happy with this kind of shaky landings: the 777 suddenly "teleport" to the RWY from 100ft due to the crash detection off, and they start to scream like mad.  :Whistle:

And of course, I'm not that happy too.

BTW with the latest FSDT Couatl update, crash detection is automatically disabled when you switch from VC to top-down F12 view in certain airports (i.e. KLAX).

 

Cheers,

Crash detection never worked right in FSX and it doesn't in P3D either. You can hit invisible objects, have an AI aircraft come close to you and get a crash, etc. etc.  I turned it off decades ago, and nobody likes realism more than I do, but CD is not realistic at all.

I must be one of the odd ones of the bunch.  If I crash, I crash into ground (my mistake, not the sim).  I have yet to find the invisible objects that a lot of folks speak of.  Then again, maybe it has to do with the fact that I own Pilot's Mesh and always have that installed for my sim.

I'm the same with realism but there is absolutely nothing realistic in crash detection.  It is flat, flat wrong and it will terminate your flight if you do a mild overspeed which is utter BS.  If you want to know how you did, it is far better to just go look at your landing or look at the analysis to see if you have a smooth approach, flare and landing.

Are we having the same discussion about P3D here because last I checked, overspeeds in P3D don't cause you to crash your plane.  I accidentally did one notlong ago in P3D with an Airbus, but she still stayed in the air.

I didn't know they changed it.  Good news.  Still...crash detection...blah.

Each Simobject has a crash box. Rarely, with 3rd party apps, this invisible box is drawn inaccurately such that the CB's geometry does not mimic the boundaries of the Simobject. When the user aircraft encounters the CB, with crash detection on, a crash occurs.

 

The simplest CB is a cube, but this may lead to the counterintuitive results that people report.

Nasty cubes!

Either I'll keep my mesh res above 10m, or definitely stop landing my PMDGs on nice-looking seaside airports, otherwise my FSPassengers company will bankrupt.

:lol:

 

I will continue to keep an eye on it : more likely It's only something screwed-up in my P3D installation. Sooner or later, I'll be forced to a clean install anyway.

Is there any other better way to overcome this yet as its not great having to turn off crash detection?

 

Does a product like GSX help?

 

For what its worth, my problem is the airport vehicles driving around crash into me mainly during pushback.. Usually after I've spend 40 mins setting up the flight... urgh...

 

Crash detection serves absolutely no function other than to cause your flight sim to crash, when you least want that to happen.
