Cessna 182 1973 - Executing a 180 Degree Turn in Clouds; Emergency Let-Downs through Clouds

Wing
Leveler
(if
installed)
control
knob
is
"ON."
However,
if
the
air-
plane
is
not
equipped
with
this device
or
gyro
horizon
and
directional
gyro
instruments,
the
pilot
will have
to
rely
on
the
turn
coordinator
(or
turn
and
bank
indicator)
if
he
inadvertently
flies
into
clouds.
The
following
in-
structions
assume
that
only
one
of
the
latter
two
instruments
is available.
EXECUTING
A
180°
TURN
IN
CLOUDS.
Upon
entering
the
clouds,
an
immediate
plan
should
be
made to
turn
back
as
follows:
(1)
Note
the time
of
the minute
hand
and
observe
the
position
of
the
sweep
second
hand
on
the clock.
(2)
When the
sweep
second hand
indicates
the
nearest
half-minute,
initiate
a
standard rate left
turn, holding
the
turn
coordinator
sym-
bolic
airplane
wing
opposite
the lower left index
mark
for
60
seconds.
Then
roll
back
to
level
flight
by
leveling
the
miniature
airplane.
(3)
Check
accuracy
of
the
turn
by
observing
the
compass
heading
which
should
be the
reciprocal
of
the
original
heading.
(4)
If
necessary,
adjust
heading
primarily
with
skidding
motions
rather
than
rolling
motions
so
that the
compass
will
read
more
ac-
curately.
(5)
Maintain
altitude
and
airspeed
by
cautious
application
of
elevator
control.
Avoid
overcontrolling
by
keeping
the
hands
off the
control
wheel and
steering
only
with
rudder.
EMERGENCY
LET-DOWNS THROUGH
CLOUDS.
If
possiBle,
obtain
radio clearance for
an
emergency
descent
through
clouds.
To
guard
against
a
spiral
dive,
choose
an
easterly
or
westerly
heading
to
minimize
compass
card
swings
due to
changing
bank
angles.
In
addition,
keep
hands
off
the control
wheel
and
steer
a
straight
course
with
rudder
control
by
monitoring
the
turn coordinator.
Occasionally
check
the
compass
heading
and make
minor
corrections
to
hold
an
approxi-
mate
course.
Before
descending
into the
clouds,
set
up
a
stabilized let-
down
condition
as
follows:
(1)
Apply
full
rich
mixture.
(2)
Use:
full
carburetor
heat.
(3)
Redisce
power
to
set
up
a
500
to
800
ft.
/min.
rate
of
descent.
(4)
Adjust
the
elevator
trim
tab
for
a
stabilized
descent
at
90
MPH.
(5)
Keep
hands
off
the
control
wheel.
(6)
Monitor
turn coordinator
and make
corrections
by
rudder
alone.
(7)
Adjust
rudder trim
to
relieve
unbalanced
rudder
force,
if
present.
