MANEUVERS
The alrpl,ane
ls
approved
for certain
aerobatic
måneuvers
up
to
a
gross welght
of
1950
lbs.,
provided
it
is
loaded
within
theapprovedweight
and
center of
gravity
limits.
(See
Airplane
Fli.ght
Manual) The
maneuvers
are
spins,
steep
turns,
lazy
elghts
and
chandelles.
APPROACH
AND
TANDING
The
airplane should
be
trlmmed
to
an
approach
speed of
about 85
mlles per
hour
with
flaps up.
The flaps can
be
lowered
at
speeds up
to
ll5
miles per
hour,
if
deslred,
and
lf
approach
speed
is
reduced
3 miles per
hour
for
each
additlonal
notch
of
flap.
Carburetor
heat should not
be
applled
unless
there ls
an
indicatlonof carburetor
iclng
slnce the use
of
carburetor
heat
causes
a reduction
ln
power which may be
critical
in
case
of
a
go-around.
Full
throttle operationwlth
heaton
is likelytocause
detonation.
The amount
of flap
used during landings and the
speed
of
the
aircraft at
contact
with
the
runway should
be
varied ac-
cording
to the
landlng
surface and existing
condltions,
both
windwise and
loadwise.
It is
generally
good
practlce tocontact
the
grotrnd
at the minimum possible safe
speed
consistent
with
existing conditlons.
Norrnalln the
best technlque
for
short and slow
landings
is
to
use
full flap
andenough
powertomaintain thedesired
air-
speedand
approach
fltght path.
Mixture
should
befullrich,
fuel
on
the
fullest
tank,
carburetor
heat
off,
and
electric

on.
Reduce the speed
during
the
flareoutand
contact

MPIfl. After
gtound contact
hold
the
nose
wheel
off as
long as
possible. As
the airplane
slols
down,
drop
tlre nose and apply the
brakes.
There
wlll
