Do you happen to have a link to the g1000 supplement stating when GPS can be used on non RNAV/GPS procedures? This one covers PRNAV and SBAS operation
The part of B-RNAV, P-RNAV, GPS procedures is clear to me, u need approval and even training for P-RNAV to use it. if its not mentioned in the book, you can't do it. Simple.
What is not clear is:
When are you allowed to fly a procedure created for VOR/ADF/DME navigation, couple the CDI to the GPS and use the GPS for navigation instead of having to use 10 different frequencies to fly a full procedure.
To my understanding this has nothing to do with RNAV which is a completely different category of procedures. A VOR approach has nothing to do with RNAV, and P-RNAV approach has nothing to do with a VOR.
P-RNAV allows you to fly arrival, initial, intermediate, missed and departure. But only if that procedure is a P-RNAV procedure

or am i realy missing something here?
