The
cabin
should
be
clean and
all loose
equipment (including the
microphone
and
rear
seat belts) should
be stowéd
or secured. For
a
solo
flight in
which
spins
will
bo
conduated,
the copilot's
seat belt and shoulder
harness
should
also be
secured,
The
seat belts
and
shoulder
harnesses
should be
adjusted
to
provide
proper
restraint
during all
anticipated
flight
conditions.
Elowever,
care should
be
taken to
ensure that
the
pilot
can
easily reach the
flight
controls
and
produce
maximum control
travels.
It is
recommended
that,
where feasible,
entries
be
accomplished
at
high
enough altitude
that
recoveries
are
completed
4000
feet or more
above
ground
level.
At
least 1000
feet
of altitude
loss
should
be allowed for
a l-
turn spin
and
recove¡y,
white
a 6-turn
spin
and recovery
may require
somewhat more
than
twice that
amount.
For
example, the recommended
entry altitude
for
a 6-turn
spin would
be
6000
feet above
ground
leveÌ. In
ed loadings.
Spins
with
baggage
loadings
or
occupied rear seat(s) are not
approved.
The normal
entry is made
from
a
power-off
stall.
rA.s the stall is
approached,
the elevator
control should
be
smoothly
pulled
to
the
full
aft
position.
Just
prior
to
reaching
the
statl "break",
rudder control
in the
desired
direction
of the
spin rotation
should
be
applied
so
thatfuil
rudder
deflection
is reached
almost
simultaneousty
with reaching full
aft eleva-
tor.
A
slightly
greater
rate
of deceleration
than
for normal
stall entries,
application of ailerons
in
the
direction
ofthe desired
spin,
and
the use of
power
at the entry
will assure
more
consistent
and
positive
entries
to the
spin. As the airplane
begins
to
spin, reduce
the
power
to idle aud
return
the
ailerons to neutral.
Both
elevator
and
rudder
controls should
be held
fuII
with
the
spin until
the
spin recovery is
initiated.
An
inadvertent
relaxation
of either of these
controls
could
result
in
the
development
of a nose-down
spiral.
Fo¡ the
purpose
of training
in
spins and
spin
recoveries, a 1 or P turn
spin is adequate
and should
be
used.
Up to
2
turns, the
spin
will
progress
to
a
fairly
rapid
rate
of
rotation
and a
steep attitude.
Application
of
recovery
controls
will
produce
prompt
recoveries
(within
1/4
turn). During
