In msfs-2024, when I start a mission and get into the plane, the engine stops. I can sometimes re-start it, but it will stop again as if the mix fuel-air was too rich. When i grab the command and change it, it gets back to its original position. So I just can’t taxi and take off.
This happens actually also in the “night fly” certification.
I suffered this a few months ago and it was an input conflict. I have two throttles - a Winwing F-18 thing and a Virpil GA quadrant panel.
When flying an aircraft with the Wingwing throttle I used a profile for the Virpil one with the axes disabled so I could still use the buttons. This combination had worked fine until I started getting the same issues you describe. Couldn’t figure out why and was forced to ‘solve’ it by simply disconnecting the Virpil one.
