That's valuable information. Can you be more specific? > So I wrote my own nasal to fill in those gaps, and/or I made my own > instruments by modifying a line or two from the generic version. Can you be more specific? What nasal are we talking about? Which instruments? > In another case, the instrument(s) look to the property > systems/electrical/outputs > and so does not work because the ufo does not have an electrical bus. :) That's an interesting hypothesis. However, I see nothing in vor.xml to support this hypothesis. There are lots of aircraft with no electrical bus. I would consider it a bug in the instrument for it to demand an electrical bus and not implement a reasonable default. This should be easy to fix. Which instruments are you referring to? > Another property the ufo fdm does not update is > altitude-agl > > etc. etc. Can you be more specific? I'm pretty sure the LOC and GS needles don't depend on altitude-agl. As far as I can tell, the only variables the OBS head depends on are being set. That's why I put up a screen shot including a property browser window. > So you can't change the FDM and expect everything that rely on > a specific FDM, to keep working. I'm pretty sure I don't expect that. See my note on the subject from a couple of hours ago. However, given that the null fdm is documented to work (according to README.io and according to getstart.pdf) I think we should discuss it when it doesn't work, especially given that it comes so very close to working. ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.
