WAAS Airport Costs?

thank you, gentlemen. I must admit I am only training to be an IFR
pilot, so I am not really up to snuff.

actually, my goal is to convince the local authorities to turn one
airport into a "general aviation" heaven. interestingly enough, the
local authorities here have more interest in developing the airport
than do the actual operators. The operators are not focused on GA, but
on big airplane airports instead. (PS: I will also ask for hangar
space creation, and some other niceties.)

now, our airport already has IFR procedures (GPS, localizer, VOR), but
no ILS. I was hoping to talk the decision-makers into a not-too-high
cost solution that takes advantage of the GPS/WAAS capabilities that
virtually all GPS's now seem to have built-in, so that we can institute
better IFR approaches with more accuracy and lower decision heights.

who are the vendors of LAAS? (I presume any WAAS capable GPS can also
take advantage of LAAS---right?) what are the cost factors of LAAS?

LAAS is nowhere near certification. LAAS approaches are not available.
You'll need a ground station broadcasting GPS correction signals in the
vicinity of the airports. But I wonder what you would need it for if you
get something almost as good as an ILS with WAAS.

Oh, so you already have a localizer approach. It's very likely that when your
WAAS approach is commissioned, the minimums will not be as good as the localizer
minimums.

AFAIK there are currently no publicly available LAAs approaches. Here's some
info on LAAS, including estimated costs, but I have no idea how old that
information is. http://gps.faa.gov/FAQ/index.htm I wouldn't hold my breath
waiting for LAAS.

With the limited information you've provided, my gut feel is you'll get more
bang for your efforts by concentrating on the FBO and hangar infrastructure.
WAAS/LAAS (at least today) are not going to give you very much capability that
you don't already have with the existing array of approaches.

This will link you to an article that describe LAAS as being delayed for
quite a while. Don't hold your breath.

this does not look like great news for WAAS or LAAS. where is WAAS
actually functioning right now? (is there a map of applicable areas?)
or is it "so much for the heavily advertised WAAS features of the
GNS480"?

Approaches that use WAAS have been commissioned all over the US. IFR-
certified units that use WAAS are still rather rare, IME. WAAS doesn't
work with non-WAAS GPS units, so the aircraft has to be fitted with new
equipment, and it just isn't economically viable for most pilots.

But there is no need for a precision GPS approach at most airports. A
standard GPS approach works most of the time.

WAAS usually covers most of CONUS, southern CANADA, northern Mexico and
Caribbean islands with accuracy sufficient to provide LPV approaches.

See http://www.nstb.tc.faa.gov/vpl.html for a map that is updated every six
minutes.

What is the 'vertical protection level' on the map? Is this the altitude (in
meters!) that waas is guaranteed? If so, it looks like over 120 meters
coverage is everywhere. This can't be, can it? What am I missing?

The principle problem with LAAS is that the government has a schedule to replace
ALL of the GPS sats with higher precision versions. I.e., the precision of GPS
is going up, without any particular new infrastructure going into place on
the ground or in the air. Which means that by the time any LAAS program got
on its feet, standard GPS, and presumably WAAS, might well offer the same
capability.
