the
plane follows a perfectly straight line. The
turning
arc
of
the nose wheel
is
30
degrees in
either
direction
and
is factory adjusted at stops
on
the
bottom
of
the forging.
The
turning
radius
of
the nose wheel
is
13
feet.
The

should
be carefully adjusted so
that
the nose
wheel reaches its full travel
just
after
the
rudder
hits its stops. This guarantees
that
the
rudder
will be allowed
to
move
through
its full travel.
Incorporated
with each
gear
assembly
are
micro-switches.
The
down
switches
are
connected individually to green indicator lights on the
instrument
panel
and
close when
the
gear
is
locked down.
The
up switches are
in
series-parallel
and
open
after
each gear
is
fully up. When this circuit opens.

is
made
just
as
the gear reaches the required position.
The gear position lights
are
dim when panel lights are on.
Located in the

quadrant
below the throttle are two micro-
switches. These switches activate
