Thank you, David. Welcome aboard!
Yes, the possibilities with Navigraph (and Aerosoft) have been explored several times in the past years, and this is the final summary:
Precision Simulator has been, and will be, used by professional customers like universities, schools, airlines etc. For this reason, Navigraph and Aerosoft cannot provide data to PSX as they are not authorized by their suppliers to sell data to professional customers, especially not at entertainment mass market prices. Therefore this service here is independent of the others, and the plan is to provide a database update to PSX users once per year (using the March cycle) to keep the costs as low as possible.
Cheers,
