with FAA Order 8400.33 for RNP-4 requirements, then the operation

must be rescheduled when FDE is available.

Both Garmin GPS navigation receivers must be operating and providing

GPS navigation guidance for operations requiring RNP-4 performance.

North Atlantic (NAT) Minimum Navigational Performance

Specifications (MNPS) Airspace operations per AC 91-49 and AC 120-

33 require both GPS/SBAS receivers to be operating and receiving

usable signals except for routes requiring only one Long Range

Navigation sensor. Each display computes an independent navigation

solution based on its internal GPS receiver.

Whenever possible, RNP and RNAV routes including Standard Instrument

Departures (SIDs), and Standard Terminal Arrival (STAR), routes should be

loaded into the flight plan from the database in their entirety, rather than loading

route waypoints from the database into the flight plan individually. Selecting and

inserting individual named fixes from the database is permitted, provided all

fixes along the published route to be flown are inserted. Manual entry of

waypoints using latitude/longitude or place/bearing is prohibited.

It is not acceptable to flight plan a required alternate airport based on

RNAV(GPS) LP/LPV or LNAV/VNAV approach minimums. The required

alternate airport must be flight planned using an LNAV approach minimums or

available ground-based approach aid.

Navigation information is referenced to the WGS-84 reference system, and

should only be used where the Aeronautical Information Publication (including

electronic data and aeronautical charts) conform to WGS-84 or equivalent.

Approaches

• Instrument approaches using GPS guidance may only be conducted

when the GNS is operating in the approach mode. (LNAV, LNAV+V,

L/VNAV, LPV, LP, or LP +V)

Advisory vertical guidance deviation is provided

when the GNS annunciates LNAV+V or LP +V.

The controlling minimums remain LNAV or LP

even when advisory vertical guidance is provided.

Advisory vertical guidance information displayed on

the VDI in this mode is only an aid to help flight

crews comply with altitude restrictions. When using

advisory vertical guidance, the flight crew must use
