The plate shows a catagory of "GLS PA DA", which I decode as "GPS
Landing System, Precision Approach, Decision Altitude" (with minimums
shown as NA). Is that the same as the LPV you're talking about?

Take a look at RNAV(GPS) RWY 36 at OSH for an example of an approach with
different LPV, VNAV, and LNAV minima.

Hmm, not so much difference as I would have thought. The LPV only gets
you another 40 feet and 1/4 mile. Better than nothing, I guess, but
still not an earth-shattering improvement.

Is the idea that the synthetic GS for the LPV will be 3 degrees like a
real GS, or will they be all sorts of different angles? I pretty much
know what power settings I need to track a 3 degree GS, and it would be
a shame if I couldn't leverage that knowledge on the LPV.
