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?

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.
