APV
PB84,
I think the answer to your question is found in the AIM (5-4-5). The LPV and LNAV-VNAV approaches are considered precision approaches despite their higher minimums (in the IPHB, they're called semi-precision). Consequently, they are flown to DA's. You see that the OKC LNAV-only approach is flown to an MDA.
Cheers!
