Hello, I bought the crj for msfs 2020, and I flew an RNP approach to nantes (lfrs) runway 21. I programed the approach into the fms before takeoff but I didn't see any vertical guidance (like the glideslope on an ILS approach). I know that on modern aircraft, there is a vertical guidance for RNP approaches. I saw vertical guidance during descent from the cruising altitude to the FAF (Final Approach Fix) but it was disappeared when I started the approach.
In addition to that, I wanted to ask if there is any way to see the RNP accuracy of the aircraft.
