EMERGENCY PROCEDURES
ICING
INADVERTENT ICING ENCOUNTER
1. Turn
pitot
heat switch
ON.
2.
Turn back
or
change altitude
to
obtain
an
outsíde
air
temperature that is
less
conducive
to
icing.
3. Pull cabin
heat
control full out and rotate defroster control
clockwise
to obtain maximum defroster airflow.
4. lncrease
engine speed
to
minimize
ice build-up on
propeller
blades.
5.
Watch
for
signs
of
induction
air filter
icing.
An
unexplained
loss
of
manifold
pressure could be caused by ice
blocking
the
air intake
filter. Adjust
the throttle as desired
to set
manifold
pressure.
Adjust mixture,
as
required
for any change in
power
settings.
6.
Plan
a
landing at the nearest airpoft. With an extremely
rapid
ice build
up,
select
a
suitable
"off
airpoft"
landing site.
7. With
an
ice
accumulation
ol
1/4 inch
or
more
on the
wíng
leading edges, be prepared for significantly higher stall
speed.
8.
Leave wing flaps
retracted.
With
a
severe ice build up on
the
horizontal
tail, the
change
in
wing wake airflow
direction
caused
by
wing flap
extension
could result
in
a
loss
of
elevator effectiveness.
9.
Open left
window
and, if
practical,
scrape
ice
from a
portion
of
the windshield for visibility
in
the landing approach.
10.
Perform
a
landing
approach
using
a forward slip, if
necessary,
for
improved visibility.
11.
Approach at
80
to 90
KIAS
depending
upon
the amount
of
the
accumulation.
12. Pedorm
a
landing in level attitude.
