The issue here is, that these airports has the closed flag set in the stock data and it looks, that nothing can’t be overrule that.
The airports are existing in the stock data and in the Navigraph data, including runways but due this flag, I assume ASOBO disable it from the WorldMap and all Garmins/FMCs …
I’m pretty sure thats the reason - when an airport is set to close, than you can’t select it - we has also set the close-flag for these airports but it set to FALSE, means open but the sim dosen’t overrule these setting from the stock data. Not selectable, also with our data.
