NORMAL
PROCEDURES
L
Use
55%
to
60%
power
while
transitioning
to
and
from
the
practice
area
(approximately
2200-2250 RPM).
2.
Lean
the
mixture
for
maximum
RPM
during
climbs
above
3000
feet.
The
mixture
may
be
left
leaned
for
practicing
such
maneuvers
as
stalls.
3.
Lean
the
mixture
for
maximum
RPM
during
all
operations
at
any
altitude,
including
those
below
3000 feet,
when
using
75%
or
less
power.
NOTE
When
cruising
at
75%
or
less
power,
the
mixture
may
be
further
leaned
until
the
RPM
peaks
and
drops
25-50 RPM.
This
is
especially
applicable
to
cross-country
training
flights,
but
may
also
be
practiced
during
transition
flights
to
and
from
the
practice
area.
Using
the
above
recommended
procedures
can
provide
fuel
savings
of
up
to
13%
when
compared
to
typical
training
operations
at
a
full
rich
mixture.
STALLS
The
stall
characteristics
are
conventional
for
the
flaps
up
and
flaps
down
condition.
The
stall
warning
horn
produces
a
steady
signal
5
to
10
knots
before
the
actual
stall
is
reached
and
remains
on
until
the
airplane
flight
attitude
is
changed.
Stall
speeds
for
various
combinations
of
flap
setting
and
bank
angle
are
summarized
in
Section
5.
SPINS
Intentional
spins
are
approved
in
this
airplane
(see
Section
2).
Before
attempting
to
perform
spins,
however,
several
items
should
be
carefully
considered
to
assure
a
safe
flight.
No
spins
should
be
attempted
without
first
having
received
dual
instruction
in
both
spin
entries
and
spin
recoveries
from
a
qualified
instructor
who
is
familiar
with
the
spin
characteristics
of
the
Cessna
152.
The
cabin
should
be
clean
and
all
loose
equipment
(including
the
microphone)
should
be
stowed.
For
a
solo
flight
in
which
spins
will
be
conducted,
the
copilot's
seat
belt
and
shoulder
harness
should
be
secured.
Spins
with
baggage
loadings
or
occupied
child's
seat
are
not
approved.
The
seat
belts
and
shoulder
harnesses
should
be
adjusted
to
provide
proper
restraint
during
all
anticipated
flight
conditions.
