eigentlich ist B-RNAV schon mit einem GPS erfüllt
B-RNAV can be achieved using inputs from VOR/DME, DME/DME or GPS. (INS may be used for up to 2 hours after the last radio or on-ground update. Loran C may be used in European airspace where suitable coverage exists and the aircraft system has been certified to FAA AC 20-121A – no JAA advisory material exists for LORAN C). The JAA has published a Temporary Guidance Leaflet (TGL) No 2, AMJ 20X2, entitled Guidance Material On Airworthiness Approval And Operational Criteria For The Use Of Navigation Systems In European Airspace Designated For Basic RNAV Operations.
