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


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.
