COLD WEATHER OPERATION
Special consideration should
be
given
to
the
operation
of
the
airplane
fuel system
during
the winter
season
or prior to
any
flight
in
cold temperatures. Proper preflight draining
of the
fuel system
is
especially important and will eliminate any free water
accumulation.
The use of additives such as isopropyl alcohol or diethylene
glycol
monomethyl ether may
also be
desirable. Refer
to
Section
8
for
information
on
the proper
use
of additives.
Cold weather often causes conditions which require special
care
during airplane operations. Even small accumulations
of frost,
ice,
or snow must be
removed, particularly
from wing, tail and all
control
surfaces
to
assure
satisfactory
flight
performance
and
handling.
Also, control surîaces must be free of any internal accumulations
of
ice
or snow.
lf
snow or slush covers the takeoff surface, allowance must
be
made
for takeoff
distances which
will be
increasingly extended
as
the snow or slush depth
increases. The depth and consistency
of
this cover can,
in
fact,
prevent takeoff
in
many instances.

Prior
to
starting
on
cold
mornings,
it
is
advisable
to
pull
the
propeller through several
times
by
hand
to
"break loose"
or
"limber"
the
oil,
thus conserving battery energy.
