Howdy, thanks for the response! I was with DeltaMike when we were experiencing the failures. It sounds as though the anti-ice should keep things running smoothly under most circumstances then?
I made a quick video to highlight what we've been experiencing.
Sorry for the poor quality. However, this mission was set with thunderstorms at 10 degrees C. You can see that even with anti-ice and continuous ignition on, the engine fails after ~5 minutes of remaining idle on the ramp. Is that intended?
