On my G1000 equipped SR22 I could not even shoot an NDB approach.
PAR approach for GA flying??
None of the airport I fly to offer such a thing. I thought these days you can only see it at military airports plus who would want to use it say in the US with abundance of other approaches- it is really archaic too.
Also NDB approaches are getting very scarce these days - if someone asked me to find an airport within 200 nm of my location with an NDB approach I would have a real tough time.
