WARNING:
Up
to 2000
feet
of altitude
may
be lost in a
one-turn
spin and
recovery;
therefore
stalls
at
low
altitude are
extremely
critical.
On
entering a
spin, the
aircraft will
roll,
very
much
like
a
barrel roll.
The
wings
will
be
near
vertical at

about the first quarter
turn of the spin. At
about the
half turn
point, the
wings are
approaching
level
but,
now, the nose
will
be
very
low--approaching vertical.
After
one
full turn has
been
completed,
the nose
will
come
up somewhat,
but
will remain
well
below the
horizon. The rate
of rotation during the
first portion
of the spin is
quite
rapid

the

aircraft nose comes
up
and remains more on the
hori-

with
possibly some shallow up and down
oscillation.
The rate
of
descent and
rate of
rotation
both
become
slower.
An
air'craft in
a
flat spin
becomes stabilized
into
autorotation
and
once in
this
condition,
the
controls
become ineffective and
recovery
is
very
difficult or may
not
be
possible.
In
complying with
the
FAA Regulation
for Normal

aircraft,
it
has been
demonstrated
that the

plane will recover after
