to
obtain
an
outside
air
temperature
that
is
less
conducive
to
icing.
3.
Pull
cabin
heat
control
full
out
to
obtain
maximum
defroster
air
temperature.
For
greater
air
flow
at
reduced
temper11.tures,
adjust
the
cabin
air
control
as
required.

inch
or
more
on

of
elevator
effective-
ness.
9.

scrape
ice
from
a
portion
of
the
