No, but it can be fixed! This is an issue with FSX/P3D and FPS. In order to see smooth fluid movements, you need lock to a frame rate that your machine can maintain consistently. To fix this:
This is known issue with Microsoft Flight Simulator 2020 and how it interacts with SimConnect (the API that feeds our software). Unfortunately, there is not much we can do about this issue until Microsoft/Asobo resolves the issue on their end with a patch. In order to verify that the error you are seeing is the same as the one described here, you must press Control + Shift + A and check the aircraft list to see if any aircraft are “Disabled”. If they are, then you have confirmed this bug. The only way to resolve it is to shutdown the FS2020 Pilot Client, restart, and reconnect to the network.
If your PTT is not working when your simulator is in view this could be due admin level permissions on your PC. It is recommended that you do not run simulator, launcher or pilot client in admin mode. If you do start your simulator and launcher in admin mode you may have to keep pilot client "in focus" in order to transmit.
