hello
with 2020.4 nightly, a window appears (but not always) when launching many helicopters (but not all), regardless of location:
"The aircraft flight dynamics model contains errors and cannot be used. (FGGroundCache::get_agl:NaN position input") Quit FG
Log shows many warnings such:
18.09 [WARN]:OSG /Users/jenkins/jenkins-root/workspace/Mac-nightly/dist/include/simgear/debug/OsgIoCapture.hxx:37: Warning: detected OpenGL error 'invalid operation' after applying GLMode 0xde1
18.09 [WARN]:OSG /Users/jenkins/jenkins-root/workspace/Mac-nightly/dist/include/simgear/debug/OsgIoCapture.hxx:37: Warning: detected OpenGL error 'invalid operation' after applying GLMode 0x806f
???? THK for answering

Obvious question - does it happen at all locations. or is it specific to one / a few starting locations ?

Okay, looks like it's a problem in the YASim FDM. Last thing - do you get the same behaviour with fixed-wing YAsim aircraft - i.e. is it specific to YAsim helicopters ? Just search for yasim in the launcher to find YAsim airplanes !

Hmm, well, I just tried the EC135 with an up-to-date git next build, and it's working fine for me - can you please tell me your git commit ID (git show -q in the flightgear / simgear source code directory) ? (Or if you downloaded FG2020.4 as an AppImage, please tell me the date)

I don't use git. I tried several versions of 2020.4 nightly, from Index of/builds/nightly, the last tried is 24/06/22

Update: To this day, I didn't get a response on the mailing list, but I found YASim aircraft to be working normally if you spawn on a final approach (or generally, in the air).

No result in these 2 cases. Why this problem does not exist with 2020.3 ???

Hello! Just picking up this older thread to say that this issue is still extant. It happens with me for all YASIM aircraft without fail, regardless of which airport is selected or if the simulation is started mid-air. This is using fgdata-next and the nightly AppImage, all running on Debian 10.
