When XPlane ships a new nav.dat and that someone (c) pushes the change to fgdata. However, we have to be quite careful about keeping the latest scenery and the nav.dat quite in sync, else there can be some very strange things happening (for instance an existing ILS sending you to no runway)...

I've mostly changed only the fix.dat. I've added some VORs, too, but I haven't submitted them anywhere yet. No ILS though.
The fixes should be completely harmless.

I can't do it, so who will it be?
Until then I'll be posting them to a separate thread. Edit: this thread.

I was also wondering about this topic. There are many airports without ILS in FG, but with it in reality. How can I add ILS freq to an airport?

Hi Guys, I'm playing version 2018.2 in Mac and I'm having problems to find some Waypoints around KSFO, like SUSEY, EBAYE, SYMON etc. Others waypoints like PORTE or AXMUL are find, but others don't.

It's this correct ? Or do I need to update my nav.dat ?

I believe the nav.dat file is pretty old and outdated. I image a new version will be available once we are able to regenerate the world scenery.

I would also like to add some fixes in FG.
It is said here that the blablabla.dat.gz-files have to be unzipped and later zipped again.
But is it possible in Win7 to do this without additional program?
If not what program would you recommend? It should be safe/reliable and free of adware and other sh*t you don't wanna have on your system. It also must not nest deep in the system and should be easily and totally removeable.

As always thx in advance.

7Zip seems good for that...?

I'm exactly in the same situation. I want to collaborate to to NAV AIDS update but the process seems overly too complex and slow for an update to become available. Also I was surprised that the various *.dat.gz files were not part of the terrasync update. Could this be feasible?

Do you confirm the best way is to unzip, modify locally, zip, test, send the updates to xplane?
