So for my bugsmasher flying IFR with Garmin 430W I file:
-G
-R
-Z
And in field 18:
NAV/RNP2 PBN/S2 PBN/O2
about to submit - lets see what happens
I'm pretty sure the 430W has baro aiding, if installed IAW AC21-36(1), and not baro vnav which would mean PBN/S1 and not PBN/S2 would be correct. Happy to be corrected. FAA AC90-100 is fairly self explanatory though.
