I'm sorry, but I still don't know what you are trying to say.
Maybe there's a misunderstanding. I'm just a customer, I bought the Split airport scenery and installed it via Orbx Central, and the ILS for RWY 05 does not show a localizer (lateral guidance). I don't see how applying "knowledge of ILS" or determining the difference to the "default ILS" is solving this for me. As fas as I can tell, the frequency (and course) I set in my approach is correct and should give me not only the glideslope but localizer as well. I think I installed it correctly, if there is something I need to do on top of this to get it to work properly, please let me know.
If I'm missing the clues all together here, please forgive me.
Thanks!
