I am running the latest stable X-Plane 11 on the latest MacOS. I have the Gizmo plugin installed from TerraMaxx so I downloaded "P_180_Avanti_II.zip" and the latest scripts. Put the P_180_Avanti_II folder in my Aircraft folder and dragged the latest scripts folder into the P_180_Avanti_II folder. When I start a flight with the P_180_Avanti_II, after takeoff and a short way into the flight it will start to fade the whole screen until it is completely black. I can still hear the audio so I know it is still in flight and if I use the instructor panel to change planes everything goes back to normal. Is there something I am missing. Why does it fade out on me?
