Hi, I’ve had two CTDs when establishing on the ILS for third-party freeware sceneries. The sceneries were the ones available for SBGR and MYNN. I have asked for support from the scenery developers and they said it was an issue with the Navdata.
Cheers!
Hi,
oh what an easy answer, great support …
To verify it, if the navdata are really the issue, you should do two additional test-flights:
On one of the two scenarios should be result in a CTD - if in both, than you have any other problem on your system. When in #1 only it´s a navdata issue, when in #2 only it´s a scenery addon issue.
Also, it is not unimportant which aircraft you were using, and if you´re using any addon-linker programs or similar else. Or, if your scenery-file is a mess, or, or, or … you see, it´s to simple to say only , it´s a navdata issue.
Which freeware sceneries do you use, that I can also try to reproduce it … Which aircraft, which flightplan, which ILS …
Cheers,
Thanks for the quick response! Yes, I agree it was a very bad response by the scenery devs to the issue.
I have already tried it without the scenery and Navdata beta without any issues.
Happened with the 787 and A330 by PMP with FBW compatibility. I use addonlinker for Aircraft and Sceneries but not for NavData since I use it every flights 
You´re welcome and thank you for your effort for testing this … we are also not perfect and we are also make mistakes from time to time, so nobody is perfect but I also guess, this is not really a navdata issue.
Thanks for the both links - let me check the sceneries and let me check if I can reproduce it - possible I find out why. Will keep you informed here - will not close this topic till I have tested this …
Please give me a little bit of time - will come back 
Thank you and again thanks for testing …

Thanks. Happened when establishing ILS. Good luck.
