Only)
The
GPSS
mode
allows
the
autopilot
to
follow
a
direct-­‐to
or
multi-­‐leg
flight
plan
from
an
IFR
GPS,
or
an
external
steering
source
such
as
an
EFIS.
This
mode
uses
ARINC
429
data.
This
mode
will
anticipate
upcoming
turns,
rounding
the
corners
instead
of
overshooting
the
next
course.
It
will
also
fly
procedure
turns
and
approaches.
This
mode
is
accessed
from
the
track
selector
mode
by
pressing
the
MODE
button
on
the
autopilot.
When
in
GPSS
Mode,
the
autopilot
display
will
show
GPSS
on
the
display.
If
ARINC
429
steering
inputs
are
present,
GPS
Nav
mode
will
be
skipped.

access
the
GPSS
mode
from
TRK
mode,
