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 traffic sensor or
Stormscope 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 see-
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

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 case.
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 Series unit Pilot’s Guide.
