Good question. I have no idea. The two-needle "hsi.xml" was already part of FG when I came aboard, already installed in the "generic" instrument setup, and used in dozens of aircraft models. In this case, as for most things in Aircraft/Instruments/*.xml, I couldn't find any documentation to indicate what the thing is modeled after. I see four different "hsi*.xml" files; I don't know what is the relationship between them. > I have never seen a HSI > containing a ADF indicator, just plain HSI for the VOR/ILS indicator (like > KI525) and on the other hand the RMI with a VOR and ADF needle (like KI228). Several responses: 1) I didn't have a real instrument in mind; I was just making the minimal fix to the existing hsi.xml. I acted on the observation that having two very similar needles was "pilot error waiting to happen". Something needed to be done. 2) An argument could be made for removing this RMI needle, but that is not a step to be taken lightly, since it would require nontrivial compensatory changes in dozens of aircraft panels. 3) FWIW S-Tec is selling a *three*-needle eHSI (one CDI plus optionally two RMI needles). http://www.s-tec.com/newsletters/approach0401/55xflying.html 4) I hear rumors that MS FS2k has a two-needle HSI, but I don't know for sure. I have no experience with FS2k ... and IMHO FGFS should be modeling real life (to the extent possible), not modeling MS. 5) The double-shafted arrow glyph will come in handy if/when somebody decides to make a KI229 or the like. - This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.

Is this modeled after a real instrument? I have never seen a HSI containing a ADF indicator, just plain HSI for the VOR/ILS indicator (like KI525) and on the other hand the RMI with a VOR and ADF needle (like KI228).

I could try merging my two repos into one. What I'm not sure is what will happen to those tags.

In the long term I hope the FlightGear project will adopt git as a replacement for CVS. However, for now I think it would be best to include the diffs from your patches in these emails rather than pointing folks to your git repo. That will increase the chances of developers -- who might not yet be so keen on git -- looking at the patches and committing them, and give those of us who are using git too the option of applying your patches directly instead of fetching your sport model branch.
