Approaches - Garmin GNS 5XXW Manual

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)

If flight plan information is imported from a
portable electronic device utilizing the Flight Stream
210 Bluetooth® system, all waypoints and flight
plan sequences must be verified by the crew.
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 the primary
barometric altimeter to ensure compliance with all
