NOTE
If
disorientation
precludes
a visual
determination
of
the
direction
of rotation,
the
symbolic
airplane
in
the
turn
coordinator
or
the
needle
of
the
furn and
bank indicator
may
be
referred
to for this
information.
Variation
in basic airplane
r€ging
or in weight
and
balance
due
to
installed
equipment
or right seat
occupancy
can cause
differences
in
be-
havior,
particularly in
extended
spins.
These differences
itre
normal and
will result
in variations
in
the
spin
characteristics
and
in
the
spiraling
tendencies
for spins of
more than
2
turns.
However,
the
recovery
technique
should
always
be used
and will
result
in the most
expeditious recovery from
any spin.
Intentional
spins
with
flaps extended
are
prohibited,
since
the
high
speeds
which
may
occur
during recovery
are
potentially
damaging
to the
flap/wing
stmcture.
LANDING
NOR,UAt TANDING
Normal
landing approaches
can be
made
with
power-on
or
power-off
with
any
flap setting
desired. Surface
winds and
air
turbulence
are usual-
ly
the
primary
factors in determining
the
most
comfortable approach
speeds.
Steep
slips
should
be
avoided
with
flap
settings
greater
than
20o
due
to a
slight
tendency for the elevator
to
oscillate
under certain combi-
nations of
airspeed,
sideslip
angle, and
center of
gravity
loadings.
NgTE
Carburetor
heat should
be
applied
prior
to
any significant
reduction
or closing of
the
throttle.
Achral
touchdown
should
be
made
with
power-off
and on the
main
wheels first
to reduce the
landing
speed
and
subsequent
need for
braking
in the landing
roll. The nose wheel is
lowered
to
the
runway
gently
after
the
speed
has diminished
to
avoid unnecessary
nose
gear
loads.
This
procedure
is especially important in
rough or
soft
field
landings.
