GPS approach safety case

wrote in message ...

My recollection is that legacy RNAV aircraft can meet the Euro
requirements
quite easily using DME/DME.

"Legacy" as in already having an RNAV system as part of the FMS that works
on a different sensor? Yes, but we're talking systems that cost as much as
many GA aircraft are worth.

Those clunky birds don't even have GPS.
Basically, Euro wanted crummy VOR aircraft out of the system.

And it seems to have had the desired effect. Navigation in Europe these
days tends to be from five-letter waypoint to five-letter waypoint (or
rather, direct to five-letter waypoint). In NW Europe at least, most routes
are now RNAV routes.
