I am using FG 2017.2.1 as a visualization for an JSBSim simulation - e.g. running flightgear with fdm=external. I am using a more or less default output setup from JSBSim. Everything works fine, except for while flightgear is running, there is a small message in the center of the screen that says "Out of fuel!" - despite the fact that the plane is flying just fine. An examination of the property tree reveals that some of the fuel properties have values, while others don't. I also get a bunch of warnings about cabin temperature being too low. Is there anything I can do to get rid of these? None of the flightgear UI settings seem to help much. This happens consistently and on multiple machines.
Thanks!
