WC, well that all makes sense, if by RAA you mean the airline group.
The ongoing phase out of ground-based NAVAIDs has strong potential to affect marginally equipped aircraft operations when the sun is not shining. As the NEXT-GEN system begins to take shape, shutting down all but 30 airport-based VORs is both cost-saving and a forced requirement towards RNP goals.
One concern beyond protecting the 'little guys' is that of redundancy - putting all of our NAV eggs into one GPS basket doesn't seem like a good idea.
