That comment may be helpful in a GPS newsgroup where the technology is
discussed in the absence of any application, however, in an aviation
newsgroup, discussions of GPS are primarily about the application, and in
that context WAAS is inseparable from GPS; in other words, in aviation
there is no application for WAAS independent GPS AFAIK. So, your above
claim is extremely off-topic, at best.

Actually he is correct. WAAS is not part of GPS. You don't need WAAS
to use GPS for aviation.

Do you know of an aviation use of WAAS that isn't tied to GPS? That is the
issue.
