3. Autopilot Power Up
It
is
essential
that
the
aircraft
be
stationary
during
the
power
up
sequence!
The autopilot master switch should be in the off position when
the
engine
is
started.
After
starting
the
aircraft
engine,
turn
on
the
autopilot
master
switch
and
keep
the
aircraft
stationary
as
the
internal
gyros
are
initialized.
This
takes
approximately
20
seconds
during
which
time
the
display
will
first
show
the
autopilot
type
and
software
version
in
lower
portion
of
the
screen.
This
is
displayed
for
the
first
10
seconds.
Autopilot
type
and
software
version
is
shown
in
figure
3a.
Figure 3a
Following the autopilot type and software version screens, the
display
show
the
words
PWR
UP
in
the
lower
right,
as
shown
in
figure

When the power up sequence is complete PWR UP will change
to
AP
OFF,
as
shown
in
figure

Once
AP
OFF
is
displayed,
the
aircraft
can
be
moved
without
introducing
centering
errors
into
the
internal
gyros.
