If
APR DWNGRADE
is not acknowledged, the system will downgrade to LNAV
service level, (
LNAV
displayed in magenta), the VDI will remain flagged "NO GP",
and no additional downgrade system messages will be generated.
If SBAS becomes unavailable on an RNAV LPV approach,
LPV
will be displayed
in yellow, but the CDI and VDI will continue to be shown. At one minute to the FAF,
APR DWNGRADE
will be displayed.
The VDI will be flagged "NO GP". Depending on the available lines of minima for
the approach, the system will switch to either LNAV/VNAV or LNAV service level.
Advisory Visual Approaches
The GIFD will provide advisory visual approaches to many runways in the aviation
database. Lateral guidance for the visual approach is aligned with the runway
bearing. The system also generates vertical guidance from the runway threshold
at a GIFD-defined glidepath (usually 3°; refer to the Garmin Pilot's Guide for
further information) allowing coupling of the autopilot to the appropriate minimums.
The pilot interface for visual approaches is an extension of the normal approach
selection method. At the end of the list of instrument approaches, there will be a
set of visual approaches added. Nominally, there will be a visual approach listed
for each runway end. The approaches will be labeled with the name VISUAL and
the runway number.
Each visual approach has two transitions: the Straight-in transition and the
Vectors-to-Final transition. The transitions will be labeled STRAIGHT and
VECTORS, respectively. The FMS creates the visual approach waypoints (fixes)
based on the runway position and course specified in the navigation database.
These are defined in the following table:
Fix
Identifier
Description
Distance to
runway
RWxxx
Runway fix defined in the navigation database. “xxx”
is the runway number and suffix (e.g. RW19L).
N/A
FINAL
The roll-out from the turn to the final approach
course is accomplished as this fix is sequenced.
3.5 NM
STRGHT
Initial fix for the Straight-in transition.
6 NM
The waypoints created by the FMS to define a visual approach are fixes stored in
the flight plan. When the approach is no longer a part of a flight plan, these
waypoints are deleted. A visual approach can be inserted onto the Active Flight
Plan or the Standby Flight Plan. A visual approach also can be inserted into a
