Hi @AndyClark20
It appears 79XA is not in the 2024 AIRAC sim database. So there’s an issue with it missing, since it exists IRL, and is recognized in the online flight planner. Don’t know why its data not getting pulled into the sim, e.g. Formatting error, mistyped named, etc.
The shame is, that data is being pulled into the online flight planner database, but not making it into the sim itself. I don’t know of any special process that private airports can opt out of the FAA database, normally they just have to be shown on sectionals, etc with a “circled P” symbol to indicate they’re private. But normally the FAA requires all airports (even closed ones that still have a runway that would be usable in an emergency) be shown on the charts.
My recommendation is to report the issue in the thread below:
