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), Standard Terminal Arrival (STAR), and enroute RNAV "Q"
and RNAV "T" 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.

System Use
In installations with two GTNs and an external GPS annunciator (See Table 2)
the GTN connected to the external GPS annunciator must be used as the
navigation source for all IFR operations.
The only approved sources of course guidance are on the external CDI, HSI, or
EHSI display. The moving map and CDI depiction on the GTN display are for
situational awareness only and are not approved for course guidance.
