I disagree. I think there is a more important problem. If you're flying direct
routes and RNAV with GPS as primary(and only random route) source of
navigation, in the event of a GPS signal degradation, you have a bit of a
balancing act to do to get back to "legacy" navigation. If you're in the
middle of the Great Plains that's no issue, but if you're shooting an approach
to White Plains it may be.

Wouldn't you be in the same situation if you were shooting an ILS
approach and the localizer went U/S?


All the best,
