SECTION
3
EMERGENCY
PROCEDURES
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
accurately.
5.
Maintain
altitude and
airspeed
by
cautious
application
of
elevator control.
Avoid
over
controlling by keeping
the
hands
off
the control
wheel
as
much
as
possible
and
steering
only
with
rudder.
EMERGENCY
DESCENT
THROUGH
CLOUDS
If
conditions
prevent
return to
VFR
flight
using
a
180°
turn,
a|
descent
through
a
cloud deck
to
VFR
conditions
may
be
appropriate.
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
approximate
course.
Before
descending
into
the
clouds,
set
up
a
stabilized
letdown
condition
as
follows:
1
.
Apply
full
rich
mixture.
2.
Reduce
power
to set
up
a
500
to
800
ft/min
rate
of
descent.
3.
Adjust
the elevator
trim
for
a
stabilized
descent
at
70-80
KIAS.
4.
Keep
hands
off
the
control
wheel.
5.
Monitor
turn
coordinator
and make
corrections
by
rudder
alone.

Check
trend
of
compass
card
movement
and
make
cautious
corrections
with
rudder
to
stop
the
turn.
