Section 4. NORMAL PROCEDURES
Refer to the 400W
Series
unit
Pilot’s
Guide
defined in
paragraph 2. 1
on
page
6 of this document for normal operating procedures. This includes all GPS
operations, VHF COM and
NAV,
and Multi-Function Display information.
For information on TIS traffic, or data linked weather see the Pilot’s Guide
addendum for optional displays. For information
on
active trallic
sensor or
Stormscopc operation and displays
see
the Pilot’s Guide addendum for
display interfaces.
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.
