ARTTY intersection and hold.
LNAV/VNAV and LNAV Approaches with Advi-
sory Vertical Guidance
GPS approaches with vertical guidance may be
either LNAV/VNAV or LNAV approaches with advisory
vertical guidance. LNAV-only approaches with advi-
sory vertical guidance only have LNAV minima listed
on the bottom of the approach plate. The glidepath is
typically denoted by a light dashed line on the vertical
profile (Jeppesen only) with an associated glidepath
angle (usually in the 3.00° range). These approaches
are indicated with “LNAV+V”.
For approaches with LNAV/VNAV minimums,
those will be controlling. For LNAV approaches with
advisory vertical guidance, the LNAV minimums will
be controlling. Approaches confirmed as “LNAV/
VNAV” approaches in the Jeppesen NavData are indi-
cated with an “L/VNAV” annunciation. At the time of
this publication, not all of the LNAV/VNAV approaches
have been identified as such in the Jeppesen NavData,
therefore some LNAV/VNAV approaches may still be
identified with “LNAV+V” annunciation.
NOTE: When flying LNAV approaches with advisory
vertical guidance, the vertical guidance may be ignored
and descent is accomplished in accordance with pub-
lished step-down altitudes and MDA.
Points to Remember for ALL Approaches
• The GNS 500W-series unit is designed to comple-
ment your printed approach plates and vastly
improve situational awareness throughout the
approach. However,
you must always fly an approach
as it appears on the approach plate .
• The active leg (or the portion of the approach
currently in use) is depicted in magenta on the
Map Page. As you fly the approach, the 500W-
series unit automatically sequences through each
leg of the approach unless “SUSP” appears above
the
OBS key. “SUSP” indicates that automatic
sequencing of approach waypoints is
suspended
on
the current leg and normally appears at holding
patterns and upon crossing the missed approach
point (MAP).
“SUSP” indicates that automatic sequencing
of approach waypoints is suspended. In some
instances “SUSP” automatically cancels (hold-
ing pattern entry). In other cases, press OBS to
manually cancel.
• For roll steering autopilots: roll steering is ter-
minated when approach mode is selected on the
autopilot and is available once the missed approach
is initiated.
• Auto-Suspend is active for Vectors To Final (VTF)
until on the “TO” side of the FAF and the aircraft
ground track is within a 45° course of the published
in bound course. At this point, it will automatically
extinguish.
This is a new feature with the 500W-
series.
• For all approaches and departures, make sure to
recheck the runway, transition, and all waypoints.
If ATC directs you to make a change, recheck each
element again.
