Is there any value to WAAS yet, beyond the "Gee Whiz" factor? Can I do
precision approaches with it yet?


646 LPV exist as of 12/21/06. Most of the LPVs are to ~250ft unless
obstacles raise the minima. Two LPVs (PUB and DLH) have been published
wth a 200ft HAT, although NOTAMed to 250' until an internal safety
assessment document is completed(expected sometime in the spring).

By the way, even if there is no LPV procedure, with WAAS you can fly to
LNAV/VNAV minima as well.
