Vertical guidance RNAV (RNP) GTN750
-
John Wayne KSNA, no issues w/ RNAV Y 20R, but w/ the RNAV Z (RNP) 20R I am not getting vertical guidance. Is this due to the aircraft / pilot not being authorized for RNP approaches? I tried it from JWARD, and from KLEVR, was at the correct alt for each of these initial apch fixes, but it just won't arm APR.
MSFS 2020, latest nav data from Navigraph (December update).
Really am enjoying flying the B58P all around SoCal including Vegas. Very nice.

Glad you're enjoying the aircraft so far. The very short answer is that this sounds like something to take up with the GPS developer.
The longer answer is that I think I have seen similar comments in the past. I think they were reference to the PMS50 GTN, and whether the user had Navigraph data installed or not may have also made a difference, but don't quote me. As I recall saying last time, this is just not a combination that I am very familiar with from my testing, since my instinct from real world flying is always to avoid selecting RNP approaches in light aircraft, for obvious reasons.

Reasonable and understood. I did not mention that what occurs is that I cannot arm APR (whether using the button in the cockpit or the one on my hardware) for this RNP approach. But "AR" (approval required) is clear, most GA pilots are not trained/certified for RNP, and most GA aircraft are not certified for it.
