Yeah no, I tested it pushing the aircraft out like 1.5km away from its waypoint and it still just hovers in space with STATE_SIMPLE_FLIGHT but Pilot: Zombie.
If the initposition is on the ground, it’ll take off and fly waypoints, if it’s not, zombie mode…
So you got a double issue, unless I’m missing something here, @FlyingRaccoon
It won’t taxi if the next waypoint is on_ground and it won’t fly if it starts in the air. It sets the right flight states but the pilot remains zombie …
Hi Sylvain,
Sorry to be a pain in your derriere here, but I got another issue/bug with these NonATCAircraft…
If the aircraft is started on the ground (initpos onGround) and fed waypoints, it will fly them… if the final waypoints are also flagged as on ground, it will land… if you flag the final waypoint as wrap_to_first (i.e. to create a looping pattern)… the simulator will outright crash. I’m assuming that the Aircraft/AI state has to have switched to STATE_SIMPLE_LANDING and Landing respectively.
I appreciate time constraints and demands with the upcoming 2024 release but there is clearly a cart full of issues related to NonATCAircraft and waypoint behaviours 
Any chance you can add the extra two issues (if not already known) and mention it again internally? It’d be much appreciated as this is really hampering a lot of cool stuff we would like to be able to do.
quick summary:
Let me know if I can get you additional debug information/crash logs/whatever to help with this.
Hello @Marajin360
Can you please create a dedicated bug report for the crash occurrence and provide a dump file as explained here: How to report a bug or crash - Bug Reports - MSFS DevSupport (flightsimulator.com)
Regards,
Sylvain
@Marajin360
(1) was this addressed in 2024 , and was it found that those issues (bug) have been corrected in the 2024 dev releases ?
@FlyingRaccoon
(2) if it was corrected in 2024, will the bug fix find its way back into 2020 ?
Tech Alpha: No, it wasn’t fixed in that build
Dev Alpha: No access to test it, Marketplace sellers only and we cannot publish in the marketplace (Both OnAir and SayIntentions are external applications and thus cannot be in the marketplace).
Well, all will be revealed in a few weeks, and if such a simple thing is not fixed in 2024, then the request will probably start flooding in .
.
(better than flooding simconnect !! ) 
At least the BUG is marked as LOGGED… that’s a good 1st step in getting a solution from Asobo.
…
Can I be very cheeky and ask if you can revisit this one too @EPellissier ? Last I checked if it very much still doesn’t work in 2024.
Sorry to add even more things to your plate 
I can probably take a look after the mid-December patch is done, although I have to admit I am not that familiar with this part of the sim. Would you have a simple C++ SimConnect test app that I could use to reproduce the erratic behaviors that you have been describing here?
Best regards,
Eric / Asobo
@EPellissier same report here
I can not provide a C++, but an C# project if that helps as well?
Same as @Kaiii3. I can very much give you the C# project for it.
I could write one in C++ if you specifically need it in C++ for some reason?
It’s just that I am more familiar with C++ but don’t worry - C# will work too! 
Best regards,
Eric / Asobo
Oh it’s incredibly simple, just pass waypoints that are flagged on ground to an AICreateNonATCAircraft() and watch it do… nothing.
I’ll knock you something together this evening 
my URL posted two years ago above still works: Microsoft OneDrive
just saw: Thats actual c++ - totally forgot that
Haha, thanks @Kaiii3
I guess this is all Eric needs then!
Thank you so much for looking into this one @EPellissier !
