So, you use BATC and get the CTDs there, or how should I understand your report here in the FSHud posting?
Cheers,
Richard
I have been using Navigraph for years. This is the first time the simulator has become unusable.
Multiple crashes here as well (in the order of 10+ CTDs), sometimes at the start of an airliner flight and other times midway but only since updating to the latest cycle and always with BATC or FSHud.
No issues flying VFR with GA and helicopters but then this is without ATC programs.
MSFS 2020.
Hi,
Can someone uninstall and reinstall the AIRAC 2603 for MSFS2020, please? No new revision, simply remove it and install it again.
I have re-uploaded the files again (14:15 UTC)
After that, please use a standard CTD test. Thank you very much!
Cheers,
Richard
Trying nowā¦stand-byā¦
Just to share AIRAC 2602 (luckily had backup this on my external hard disk) for those who wish to revert, while we all patiently wait for 2603 rev 2. Hopefully it wonāt take us long.
I have removed the link - it is not allowed to share our data for public. You breached our ToS ā¦ It is not allowed to share any data, current or old.
Have you tried, what I have written?
Thanks for your understanding
Richard
ohhh sorry about that. I had missed your earlier message. I will do a test now
No probs, thanks for your help ā¦ I know, you wanted only to help 
Cheers,
Richard
So far so good, no crash and Iām midway along my (short) route.
All I did was to uninstall the MSFS 20200 core navadata and reinstall.
Iāll post if there are updates to share.
Fabio,
Thank you very much for your feedback and your effort for testing ā¦ Cross your fingers, that you reach your destination safely 
Cheers,

Iāll try. AIRAC removed and reinstalled. On the LHR-LAX route. With a PMDG 777-200ER aircraft. Iāll use the FSLTL traffic injector. I hope I get there.

I can confirm that reinstalling has fixed the issue for me so far. I did a short touch-and-go at EDDF with FSLTL traffic enabled and the fresh AIRAC cycle, and everything worked fine.
Thanks a lot for looking into this!
The first attempt didnāt last long. WASM crash on PMDG plane. Itās possible that the PMDG files were also corrupted during previous crashes.

It could be because PMDG uses its own dataset, which has nothing to do with the current issue or the BGLs from MSFS2020.
Thanks for testing!
Cheers,
Richard
I have refreshed the PMDG FMS data again, with the crash being mistimed from EFB. I am trying again, refreshing the data from Hub. This time there was no WASM crash. (During alignment.) This was unrelated to the original problem.

My sim is still crashing, even with me removing and not starting with the other addons I had, same issue, FSHud load, instant CTD. Removal of current update back to normal. Rev 1 doesnāt resolve for me. Maybe can prolong the issue with certain airports, but ultimately still caused by this.
Testing is going on again. (LHR to LAX) Iāve now made it over the ocean. So far no problems. Weāll see, itās still a long way to Los Angeles.
What happened is that not only Navigraph released an update, but it also came to MSFS. At that time I updated AIRAC first and then MSFS. This could have caused the problem.

Hi,
No, IĀ“m honest - I think the initial upload of our files was corrupt and/or buggy, because I discovered during my analyses that some BGLs were missing from the dataset that was exported from our parser. So, my personal assumption is that something happens during file compression.
IĀ“m pretty sure that this has nothing to do with any MSFS update. When I have more time again, I will look into how I can test such things after compression and after upload. It takes me nearly 24 hours to identify this, and the last couple of hours were not so funny 
Sorry, I was a little bit annoyed and frustrated in the last couple of hours. Still monitoring the forum ā¦
Cheers,
Richard
