Since RF legs are not simulated on trainer, our approach has been to create short segments that simulate the curved path; the drawback is that those segments are linked via waypoints named Y1,Y2,....,and are visible on moving map, though intended for internal use of the GPS unit only.
RF-based approaches can be simulated on default GNS500 and G1000 units (mod version available at fsAerodata), or any other GPS unit that is based on flightsim database. Please notice that SIDs/STARs are only available on Prepar3D.
A total of 740 procedures are available worldwide on latest AIRAC 1804. A comprehensive list is available on the following document:

Enjoy the flights!
