Perhaps you should use some of your vaunted research skills to see what
the accuracy of WAAS is. It's better then a ILS and the WAaS approachs
have the same minimums as the ILS approachs.

I have indeed done the research. The whole reason for LAAS is that WAAS isn't
good enough to replace ILS entirely. WAAS can match some Category I
performance. LAAS will be needed to get to Category III, and since you need
Cat IIIc to replace ILS, WAAS certainly isn't going to do it, and LAAS
probably won't do it for a while yet.

If you think that WAAS is better than ILS, you need to tell the government
about it right away, so they can save billions of dollars of development costs
on LAAS.
