XSG-4556

The ILS 12 at LEBB is in the latest default nav data and works fine for me.

Sorry - I cannot reproduce this issue.

Thanks for your comment.
The ILS is indeed the nav data, I mentioned I can see in the FMC. However it doesn't appear in the XPlane map (the one that appears when you press "i") and I cannot use it. I cannot tune it. I have tried with several aircraft and airport sceneries. I use Ortho scenery and XEurope but I don't think that's related. Could it be?
Can you actually tune the ILS and fly an approach with it?
I attach a screenshot where you can see ILS30 works but ILS12 doesn't.

Yes, I successfully flew the approach to runway 12 at LEBB on 111.55 with the default nav data. The ILS appeared on the map.

Ok so I guess it's some weird issue at my end then. THanks for checking.
Would you have any suggestion about how to fix this or where to ask for help? I'm really clueless, since even with the default airport it doesn't work.

Thank you

It is worth mentioning that there are 5 possible sources of nav data in X-Plane 11 !!! You should search for any conflicting data. But, these sources are additive, so it's hard to see how the LEBB ILS12 data is being suppressed,

In increasing order of priority (data is matched on a navaid by navaid basis from each source):

1. Default data shipped with X-Plane. This is a one-off dump from Navigraph.and is not frequently updated:

   X-Plane 11/Resources/default data/earth_nav.dat, earth_fix.dat, earth_awy.dat and CIFP data (approaches for FMS)
   

2. 3rd party subscriptions (eg. Navigraph, Aerosoft) purchased by user at extra cost:

   X-Plane 11/Custom Data/default data/earth_nav.dat, earth_fix.dat, earth_awy.dat and CIFP data (approaches for FMS)
   

3. Updated FAA approaches, not shipped with the sim, but an optional update from FAA-published data:

   X-Plane 11/Custom Data/FAACIFP18
   

4. Curated ILS data maintained by Robin (me!). Intended to support the latest airport data from the Scenery Gateway. Corrects poor data quality in Navigraph and Aerosoft data:

   X-Plane 11/Custom Scenery/Global Airports/earth nav data/earth_nav.dat
   

5. User-defined corrections created in the sim's map UI. Cannot be used to remove/suppress data:

   X-Plane 11/Custom Data/user_nav.dat and user_fix.dat
   

Finally, there is an option for a sim-wide global override of the nav data, usually used by commercial flight schools with their own data sources.This overrides all other data sources, if present (rare):

X-Plane 11/Custom Data/Earth_424.dat

Let me know if you find the issue!
