Hi,
I have checked both airports now. The runway idents on both airports are completely out of date (in the stock scenery and also in all third-party scenery, which I have tried), and therefore, you don´t see any terminal procedures.
ZULS (stock scenery and also
… ZULS offered in Marketplace:
… and here the reality:
ZUCK (stock scenery and also the free 3rd party scenery, which I have tried):
… and also here the reality:
You see, ZULS has 10LR/28LR and not 09/27 nor 09LR/27LR as in the marketplace scenery (there was still a posting here about this)—the same for ZUCK. ZUCK has 02LR/20LR and 03LR/21LR …
You still have all procedures in your data, but due to the wrong runway identifiers, the sim can´t assign these procedures to the correct runways and disables them for this airport.
So, this is not a navdata issue, it´s a scenery issue. At that moment, when the runway-ident is correct as in the real world, you will immediately see the terminal procedures (because they are still included).
Sorry, we can´t do anything here; this is a limitation from MSFS 2020.
Cheers,
Richard
