And it is not only FAA land. Canada Australia and and NZ have had GPS approaches for some time. Last year with great fanfare when our beloved CAA approved 6 airfilds for GPS approaches they joined France Germany and even Hungary in Europe who have had GPS approaches for some time. In Germany the airfield does not have to be licenced. The only requirement is a AWOS typoe of weather reporting.
While the CAA is populated by people whose only knowledge of aviation is the Club/Business cabin of the airliner they travel around to endless meetings, we do not have a chance.
