Mutt,
In Rockwell-Collins installations, you know the types, once the approach is loaded and armed; intercepting the VNAV path will transition the flight guidance to APPR and VGP. Once VGP is captured, the altitude selector can be set to the missed approach altitude. It is taught, "it's just like an ILS".
Funny, that the LPV mins are lower than the RNAV AR procedure minima. All our planes now have LPV installed and, with LOA, is available.
The LNAV mins would require setting the alt selector to mins+ 50' and use of LNAV/VNAV. The system would fly, or display to the pilots, the LNAV and VNAV paths.
