Qwntm,
About explains it all.
Europe didn't invent GPS, develop, fund, build, or deploy required equipment (satellites) for its use, yet guardedly uses same anyway and would
like to have their grubby little hands on the switch, all without pitching in a dime for its use.
Let 'em develop their
own ...so they can enjoy the usual cost overruns and tax their citizens accordingly. Build it I say...bravo!
Meantime, can enjoy GPS use in the USA and if equipment 'G' installed, accept the ATC phrase...cleared direct to destination, and when within range, cleared GPS approach...
