190-00356-03 Rev. D AFMS, Garmin GNS 4XXW GPS/SBAS SystemPage 10 of 19 FAA APPROVEDwith FAA Order 8400.33 for RNP-4 requirements, then the operationmust be rescheduled when FDE is available.Both Garmin GPS navigation receivers must be operating and providingGPS navigation guidance for operations requiring RNP-4 performance.North Atlantic (NAT) Minimum Navigational PerformanceSpecifications (MNPS) Airspace operations per AC 91-49 and AC 120-33 require both GPS/SBAS receivers to be operating and receivingusable signals except for routes requiring only one Long RangeNavigation sensor. Each display computes an independent navigationsolution based on its internal GPS receiver.Whenever possible, RNP and RNAV routes including Standard InstrumentDepartures (SIDs), and Standard Terminal Arrival (STAR), routes should beloaded into the flight plan from the database in their entirety, rather than loadingroute waypoints from the database into the flight plan individually. Selecting andinserting individual named fixes from the database is permitted, provided allfixes along the published route to be flown are inserted. Manual entry ofwaypoints using latitude/longitude or place/bearing is prohibited.It is not acceptable to flight plan a required alternate airport based onRNAV(GPS) LP/LPV or LNAV/VNAV approach minimums. The requiredalternate airport must be flight planned using an LNAV approach minimums oravailable ground-based approach aid.Navigation information is referenced to the WGS-84 reference system, andshould only be used where the Aeronautical Information Publication (includingelectronic data and aeronautical charts) conform to WGS-84 or equivalent.2.6 Approaches• Instrument approaches using GPS guidance may only be conductedwhen the GNS is operating in the approach mode. (LNAV, LNAV+V,L/VNAV, LPV, LP, or LP +V)NOTEAdvisory vertical guidance deviation is providedwhen the GNS annunciates LNAV+V or LP +V.The controlling minimums remain LNAV or LPeven when advisory vertical guidance is provided.Advisory vertical guidance information displayed onthe VDI in this mode is only an aid to help flightcrews comply with altitude restrictions. When usingadvisory vertical guidance, the flight crew must usethe primary barometric altimeter to ensurecompliance with all altitude restrictions inaccordance with the LNAV or LP approachprocedure.
