Does anyone know if they've fixed the AI and ATC?

I distinctly remember in previous versions watching the AI aircraft bounce off the ground repeatedly in an attempt to reach an incorrect flight level given to them by the ATC. That kind of ruined the illusion for me.

It's a great sim, overall, I think it has a different set of priorities from MSFS, which is totally fine. I only wish I could have the best of both worlds.

The ATC AI is still pretty awful I'm afraid. I would look into VATSIM if you like realism.

PilotEdge is IMHO better option than Vatsim, although it is paid for.

Perhaps the flight level given by ATC is correct, but the instrument calibration is not set correctly.

MSFS has similarly awful ATC though.

If you really want good ATC, yeah VATSIM or IVAO.
