4.2 Approaches without Vertical Guidance
The 400W Series unit
supports Localizer Performance
approaches
(annunciated
as
LP). Published LP mtnimums will be controlling in this
ease.
NOTE:
If flying an LP approach, be prepared to fly the LNAV only
approach prior to reaching the final approach fix (FAF). If the
GPS
integrity is not within
LP
approach limits, the system will
notify the pilot by a downgrade
to
LNAV message.
For additional information on LP approaches refer
to the
400W Series unit
Pilot’s Guide.
4.3 Autopilot Operation
The Garmin 400W Series may be coupled to
an
optional autopilot if installed
in the aircraft when operating as prescribed in the
LIMITATIONS section
of
this
manual.
For lateral guidance, some installations may utilize GPSS or
GPS Roll Steering in lieu of the analog deviation information. If an HSI is
used with GPSS engaged, the pilot should
rotate the
course pointer as
prompted on the 400W Scries unit to prevent loss of situational awareness
and to prevent the aircraft from turning inappropriately if the autopilot is
switched from digital (GPSS) to analog mode. For autopilot operational
instructions, refer to the FAA approved Flight Manual or Flight Manual
Supplement for the autopilot.
4.4
Coupling the Autopilot during approaches
The Garmin 400W Scries supports analog and digital (GPSS) control
interfaces to
an optionally
installed autopilot.
Some autopilots
revert to
ROLL mode (wings level) and/or flag a NAV failure if the digital data
becomes unavailable or is inhibited. The CDI selection of VLOC should
inhibit the digital control interface. When switching between
GPS
and
VLOC the pilot should be aware that the autopilot may need
to
be re¬
engaged into APR or NAV mode after changing the CDI
source.
Autopilot coupling
to
GPS vertical guidance requires that the autopilot be
engaged in an analog APR mode identical
to coupling to
an ILS. Some
autopilots may
revert
to ROLL mode when the navigation outputs of the
400W
Series unit sequence
to
the final
approach fix.
