Bush Prepares for Possible GPS Shutdown

So, you're saying there are no GPS approaches whose missed approach
procedures rely upon GPS?

No, I didn't read that anywhere in his post. I believe his intent was to
say that it's obvious that many a liberal will go nuts about how we're all
screwed now that the government has a plan to shut down GPS (which I had
always understood that this was in place anyway). If terrorists are somehow
using our own GPS system against us, then I'm all for shutting it down (or
limiting it to military use somehow).

More the reason to keep the VOR's working.

Gotta be a "liberal" to be concerned about that, huh?

Now this line of reasoning scares me. That, and that the previous
sentence will be completely misconstrued by all the red-staters.

Aren't you required to have means to execute a non-GPS approach at either
your destination or alternate to be legal?

The real impact of this sort of thing will be (1) to convince the
Europeans/Russians/Chinese to deploy their own GPS-type system (effectively
obviating the advantage of being able to shut down the US system) and (2) to
prevent use of GPS as a true sole-source navigation system.

The U.S.S.R. had one at one time. What happened to it? Couldn't afford the
upkeep?

Yes. However, if you are WAAS equipped then there is no such requirement.

Not necessarily. Depends on the GPS.

Dunno about that, but according to an article in the most recent AOPA Pilot, you
can't shoot a WAAS approach without some other navigation system (like a VOR
glide slope receiver) in the plane.

How does one get to the next approach w/o GPS if the missed approach on the
GPS approach requires a GPS?

This isn't just a "GPS shutdown" question, but a more generic "dealing with
failure" question. Still, one is legal with a single VOR and VOR
approaches can have VOR-based missed approaches.

I did not see that article, and cannot locate it just now. But I don't
understand the logic that would imply that for a TSO146 GPS unit.

Can you elaborate?
