Doing an RNAV

[Woodwad]

I live in Santa Cruz County in CA where an airport exists, KWVI (Watsonville Muni). I have similar issues where IAFs exist on actual approach plates. But around KWVI in MSFS do not exist. Say if I want to do an RNAV from KSJC (San Jose) to KWVI and set up in Flight Plan and choose PROC and the drop down has RNAV for rwy 2 there are 4 choices. I pick one and Activate. MSFS does not recognize any of the IAFs. but does recognize the FAF FOXOV. There is no vector I can fly to in the GPS to a IAF to the IF to reach my FAF. X-plane does not encounter this. It recognizes all. I thought MSFS was supposed to be the more advanced flight sim. It has the eye candy but not the flight plan accuracies. Is there a kind of an update that needs to be done? And how?

You'll need a Navigraph Navdata subscription for that: https://navigraph.com/products/navigation-data

So, in other words I can not do a RNAV flight MSFS without Navigraph Navdata?

Yes you can: Create an IFR low or high level flight with an RNAV approach where available. Fly the whole flight including approach in GPS mode on the GPS or PFD; on approach select APR mode on the autopilot and you'll intercept the glideslope just as you would on a 'normal' ILS approach. On an RNAV approach there's no ILS frequency required or any other ground-based beacon used for guidance. A low-cost airline here in Europe (easyJet) are testing a new guidance system for the whole flight in this way - satellite guidance only is used for the entire flight: https://mediacentre.easyjet.com/story/16986/easyjet-takes-to-the-skies-with-iris-next-generation-air-traffic-communication-service
