No one said that one needs WAAS to use GPS for aviation.

Perhaps, but some seem to assume that all aviation GPS uses WAAS,
which is not true. And some seem confused concerning the accuracy of
GPS, with or without augmentation by WAAS.

Obviously, there
are non-WAAS-enabled GPS receivers. However, do you know of some use
of WAAS in aviation that _doesn't_ involve GPS? I don't.

All en-route navigation can be (and often is) conducted without WAAS.
There are many GPS receivers (in aviation and in other applications)
that do not use WAAS.

Once again, you introduced an incorrect interpretation of my question, and
merely re-stated what was I wrote in the previous paragraph. Do you really
not get this, or are you trying to deliberately mislead people in this
newsgroup?
