Sim crash at ZGSZ and ZGGG with fsltl models

[daniv1989]

I have got a problem with MSFS crashing at ZGSZ and ZGGG when loading traffic both with fsltl injector and beyond atc. It used to work fine and as late as 06-06-2025 I used ZGSZ with traffic without problems but suddenly it crash when loading traffic. I have read different places it could be due to bad navigraph data like this one

CTDs at VHHH with FSLTL

Hello, in MSFS with AIRAC 2410, if near VHHH and with Navigraph installed, I get CTDs, and a few other users on a couple of Discord servers have reported similar issues. At first, we suspected the cause was FSLTL, the traffic injector, but I did some testing with a clean community folder and without the scenery installed, and it only CTDs with FSLTL and Navigraph installed; there is no crash if Navigraph is uninstalled. This issue happened for me with both rev.1 and rev.3, and another user repor…

Is it something you can look into?

Hi,
I will compare the current cycle with the previous to look if there are changes, but I’m 100% sure, that the reference link has nothing todo with your current situation. CTDs don’t come always from the navdata. It can be happened from a oot of other things too, or any combination of things.

I will compare the records against the previous 2-3 cycles to filter out the differences.

Cheers

Have you had a chance to compare yet? I still believe this has something to do with the lastest cycle. I had no problems before that. When I load traffic at ZGSZ with beyond atc with the latest navigraph cycle installed, it crashes. When it is not installed it doesn’t. I get a lot of ctd’s now which i didn’t some weeks ago. I have tried after a complete reinstall with a litle as possible installed but it still crashes. Other support forums suggest bad nav data too. It’s just very hard to believe it has nothing to do with the lastest cycle. it was after that release the problems started

Hi,
Sorry, I forgot it. Thanks for the reminder. Will do it in the next couple of hours.

CTDs are, in most cases, a combination of issues. Our reference is a base system without any 3rd party scenery or other packages.

There was a similar posting about CTDs with FSHud; the solution was not the navdata and it shows how difficult it is to analyze such CTDs.

Sim crashing on approach to EKCH

Yeah it works fine when I don’t start FSHUD. I was able to find the solution in the FSHUD discord group. Weirdly you download and install the freeware ESGF Falkenberg scenery. Apparently relates to the below issue: https://devsupport.flightsimulator.com/t/requestfacilitydata-for-esgf-airport-causes-ctd/14061

I will compare the records to see any differences between the current and 2-3 previous cycles.

PS: the question is, do you see the same CTDs at this airports without FSLTL too?

[daniv1989]

No, but I dont see it with fsltl on through beyond atc and navigraph data of. it has to be traffic related.

[NAVData]

I have compared now both airports (ZGSZ and ZGGG) between 2506, 05, and 04. There are zero changes between these three cycles. So the current data are identical to the last three cycles at least with these two airports.

I flew also two patterns on both airports, inside the cockpit and with external view. No CTDs …

MSFS2024 (latest version, means no beta), AIRAC 2506 rev. 1 installed, standard stock sceneries and with the stock C172 with the G1000 equipped.

Sorry, I can’t reproduce your CTD
