NORMAL
PROCEDURES
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 1-
turn
spin
and
recovery,
while
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
level.
In
any
case,
entries
should
be
planned
so
that
recoveries
are
completed
well
above
the
minimum
1500
feet
above
ground
level
required
by
FAR
91.71.
Another
:reason
for
using
high
altitudes
for
practicing
spins
is
that
a
greater
field
of
view
is
provided
which
will
assist
in•maintaining
pilot
orientation.
The
normal
entry
is
made
from
a
power-off
stall.
As
the
stall
is
approached,
the
elevator
control
should
be
smoothly
pulled
to
the
full
aft
position.
Just
prior
to
reaching
the
stall
"break",
rudder
control
in
the
desired
direction
of
the
spin
rotation
should
be
applied
so
that
full
rudder
deflection
is
reached
almost
simultaneously
with
reaching
full
aft
eleva-
tor.
A
slightly
greater
rate
of
deceleration
than
for
normal
stall
entries
or
the
use
of
partial
power
at
the
entry
will
assure
more
consistent
and
positive
entries
to
the
spin.
Both
elevator
and
rudder
controls
should
be
held
full
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.
NOTE
Careful
attention
should
be
taken
to
assure
that
the
aileron
control
is
neutral
during
all
phases
of
the
spin
since
any
aileron
deflection
in
the
direction
of
the
spin
may
alter
the
spin
characteristics
by
increasing
the
rotation
rate
and
changing
the
pitch
attitude.
For
the
purpose
of
training
in
spins
and
spin
recoveries,
a 1
to
2-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
of
from
1/4
to
1/2
of
a
turn.
If
the
spin
is
continued
beyond
the
2
to
3-turn
range,
some
change
in
character
of
the
spin
may
be
noted.
Rotation
rates
may
vary
and
some
additional
sideslip
may
be
felt.
Normal
recoveries
from
such
extended
spins
may
take
up
to
a
full
turn
or
more.
Regardless
of
how
many
turns
the
spin
is
held
or
how
it
is
entered,
the
following
recovery
technique
should
be
used:
