unit will revert to terminal limits to support
navigation to the missed approach when the
message is acknowledged.
6. Capture the glideslope as you would an ILS
glideslope.
7. As you cross LOTKE, the destination sequences
to the MAP ("RW31", the runway threshold).
With the needle on the external CDI (or HSI)
centered, fly toward the MAP, observing the
altitude minimums dictated by the approach
plate.
8. When viewing the Map Page, you'll note
that the final course segment is displayed
in magenta (the active leg of the flight plan
always appears in magenta).
9. As you approach the MAP, a waypoint message
("DTK 312° x S") appears on the bottom of
the screen.
10. Once the unit crosses the MAP (defined as
the runway end waypoint), sequencing will
be suspended. Prepare the aircraft for missed
approach operation. Press the OBS key to
sequence to the Missed Approach procedure.
11. Fly the guidance provided by the unit to the
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 indicated
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 published step-down altitudes
and MDA.

Points to Remember for All Approaches

• The GNS 400W-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 400W-
series unit automatically sequences through each
leg of the approach unless "SUSP" appears above
the OBS key. "SUSP" indicates that automatic
