GARMIN INTEGRATED FLIGHT DECK (GIFD) APPROACHES
The purpose of this section is to provide an overview of the GIFD capabilities
and operation related to GIFD Approaches.
Detailed descriptions as well as operating instructions of these approaches
are provided in the applicable Pilot s Guide and Cockpit Reference Guide.
RNP approaches operation
The GIFD is capable of performing approaches with GNSS guidance also
designated as RNP approaches.
RNAV (GPS) or RNAV (GNSS)
– LNAV, LNAV+V magenta annunciations in CDI
LNAV approaches provide lateral GPS--based guidance to legs defined by
the navigation database.
Vertical deviations may be available if the necessary information to construct
a vertical path is contained in the database.
Any vertical path information for LNAV approaches is strictly advisory.
There is no guarantee that stepdown fix altitudes will be honored and the
crew must level off at the MDA if the runway is not visible.
LNAV approaches may be executed with or without SBAS, and advisory
vertical guidance is dependent on sufficient GPS vertical error estimates
rather than SBAS vertical integrity.
LNAV+V approaches do not downgrade in general because they do not
require SBAS, although high GPS vertical error estimate anomalies could
result in loss of advisory vertical guidance.
If GPS is lost the LNAV approach will be aborted.
RNAV (GPS) or RNAV (GNSS)
– L/VNAV magenta annunciation in CDI
LNAV/VNAV approaches add published vertical guidance in addition to LNAV
guidance. They are different from LNAV+V in that the vertical deviations are
not advisory, but rather published guidance.
The minimums of an LNAV/VNAV approach represent a DA rather than an
MDA.
Execution of an LNAV/VNAV approach does not require SBAS integrity, as
long as a system is configured to support barometric VNAV for approach.
