Default IFR with a VFR GPS

Yes, and the project is driven by a proposed charging scheme, where a
low accuracy signal (roughly equiv to the US one) is free and a higher

The integrity service will be fee-based.

Since the free signal from the USA is plenty good enough for en-route
navigation of cars, boats, and planes, it is pretty obvious that any
attempt to raise money from planes would have to involve authorised
GPS approaches being conditional on the carriage of a prepaid decoder
for the "better" signal.


Seems like one possible solution.

What I don't get is who will bother to pay. ILS is nearly everywhere,
and nonprecision NDB/VOR approaches are OK for most of the rest. Any
commercial transport will still need to carry all the equipment.

Any national security crisis bad enough to cause the US one to be
turned off will also turn off the Euro one.


It's typical European political stupidity.


Maybe not stupidity. Perhaps more an ego thing.

There's also a Russian system, Glonass; not sure where it's at.


IMO, GLONASS is not a viable system.
