I am aware of that, and I'm certainly not pretending to be "inventing"
something here. Just seems to me that before we went whole-hog GPS we were
seeing smart loran and RNAV boxes that could integrate a number of source
signals. Then we threw it all away to go GPS. I think we could develop a smart
interim solution using a mix of GPS, eLoran (which has come a ong way since we
all turned our backs on it) and traditional graound-based nav aids.

Get rid of the VOR's? Sure. Do it hastily and without forethought? That would
be foolish, in my opinion.

Because you are talking about using a single, much less reliable ground based
signal to back up a system that uses dozens of redundant, much more reliable
signals (higher frequency, line of sight that cannot be obscured by mountains).

It amazes me that intelligent pilots can regard GPS as if it were one single
station on one single frequency. This VOR = GPS thing is all in your mind.
Its like saying that one walkie talky equals the entire cell phone system.
