That is a different kind of thing to LPV.
What you see there, I am pretty sure, is a GPS databse version of the continuous descent profile which is nowadays shown on a lot of Jepp charts for non precision approaches.
I know some people have discovered then can fly these CDAs with their existing GPS/autopilot installation right now.
The initial parts of an LPV approach are flown in GPSS mode, but the final approach segment is flown in NAV (APR) mode
I find that baffling, but I have never dug into this (no need to know) so I can't argue
How does the AP switch over from say HDG to say APR mode?
