This includes
all
GPS

VHF

and Multi-Function

information.
For
information
on
TIS
traffic,
or

see

Although
intuitive
and
user
friendly
the
400W
Series
unit
requires
a
reasonable
degree
of
familiarity
to
prevent
operations
without
becoming
too
engrossed
at
the
expense
of
basic
instrument
flying
in
IMC
and
basic
sec-
and-avoid
in
VMC.
Pilot workload will be
higher
for
pilots
with limited
familiarity
in
using
the unit
in
an
IFR
environment,
particularly
without
the
autopilot
engaged.
Garmin
provides
excellent
training
tools
with the
Pilot's
Guide
and
PC
based simulator. Pilots should take full
advantage
of
these
training
tools
to
enhance
system
familiarization.
Use
of
an
autopilot
is
strongly encouraged
when
using
the
400W
Series
unit
in
IMC
conditions
4.1
Approaches
with
Vertical Guidance
The
400W
Series
unit
supports
three
types
of
GPS
approaches
with vertical
guidance:
LPV
approaches,
LNAV/VNAV
(annunciated
as
L/VNAV)
approaches,
and
LNAV
approaches
with
advisory
vertical
guidance
(annunciated
as
LNAV+V).
For
LNAV
approaches
with
advisory
vertical
guidance,
the
400W
Series
will
annunciate
LNAV+V
indicating
vertical
guidance
is available.
LNAV
minimums
will be
controlling
in
this
ease.
NOTE:
If
flying
an
LPV
or
LNAV/VNAV
approach,
be
prepared
to
fly
the
LNAV
only
approach
prior
to
reaching
the
final
approach
fix
(FAF).
If
the
GPS
integrity
is
not
within vertical
approach
limits,
the
system
will
flag
the vertical
guidance.
This
may
be
annunciated
by
a
downgrade
to
LNAV
message.
For
additional information
on
approaches
with
vertical
guidance
refer
to
the
400W
Scries
unit Pilot’s
Guide.
