OK, I think I see what is going on. For a properly-slaved DG or HSI or similar instrument, we shouldn't be looking at /instrumentation/heading-indicator/*. That's wrong. However, it is also wrong to look at /orientation/*. There is a third way, the correct way: /instrumentation/heading-indicator-fg/ especially /instrumentation/heading-indicator-fg/indicated-heading-deg To make all this work correctly requires more per-aircraft fussing than I had hoped would be necessary ... but it's all fairly straightforward. If you would like me to explain any of it, I'll be happy to oblige. (I'm told it is "detestable" to put explanatory comments in the code.) I believe the following patch suffices to bring the c182 and c182rg up to full performance. http://www.av8n.com/fly/fgfs/hsi-etc.diff One thing that I have *not* done but which might make sense as a migration strategy would be to create a new hsi+.xml file in parallel with the old hsi.xml file, since there are about a dozen aircraft that depend on hsi.xml and would break if they were forced to switch from heading-indicator to heading-indicator-fg without proper preparation. Then, once the preparation is made (such as providing proper power to the HSI), we can deprecate the old hsi.xml. Or does somebody have a better migration strategy? ------------------------------------------------------------------------- Using Tomcat but need to do more? Need to support web services, security?
