Last first: LPV IAPs are indeed precision IAPs.

The AIM refers to them as APV approaches, approaches with vertical
guidance. For alternate purposes, they're to be considered non-
precision.

First, the term APV is applied to any FAA approach with vertical
guidance that does not meet the precision approach requirements of ICAO
Annex 10. The FAA does not agree with Annex 10 because the FAA
considers LPV IAPs to be precision IAPs and, in fact, use ILS obstacle
clearance containment areas for obstacle protection.

An LDA with a G/S is also an APV because it clearly does not meet any
definition of a precision IAP.

As to the alternate requirements, your statement is incomplete. You
cannot plan to use the precision line of minimums on a WAAS IAP for
alternate planning purposes. But, if WAAS LPV is available when
arriving at the alternate you may use the LPV *precision* line of minima.
