Hi Noel,
I am personally running FlightSim Commander 9, and importing the flight plans both in FSX and Windows, I do update every month the AIRAC data from NAVIGRAPH, and the install is easy in FSC 9.
From a graphics point of view, the Carenado TBM-850 is really nice, but does not look to be fully simulated concerning navigation unfortunately.
The Aivlasoft EFG is a free software for 30 days as far as I know.
Cheers.
Vincent
