Flight In Icing Conditions - Beechcraft C23 SUNDOWNER 180 Pilot Operating Handbook

Section X
BEECHCRAFT
Safety Information
Remember that
regardless
of its
combination
of
deicinglanti-icing
equipment, any
aircraft
not fully
equipped and functional for
IFR
flight is not
properly
equipped for flight in icing
conditions.
An
airplane
which
is not approved
or certificated
for
flight in icing conditions,
not fully
equipped,
or
which
does not have
all
critical areas
protected
in
the
required
manner by fully operational equipment
must
not be exposed to icing encounters of any
intensity. When icing is detected,
the
pilot
of
such
an aircraft must make an immediate
diversion by
flying out of the area of
visible moisture
or
going
to
an altitude
where
icing is not encountered.
Some
models of Beech
airplanes
were
approved for
flight in certain limited icing
conditions
under the
FAA's Bureau
of
Flight Standards
Release
No. 434.
Under this
release, properly
equipped
airplanes
are
approved for flight
in light to
moderate
icing
conditions
only.
These aircraft are not approved for
extended
flight
in
moderate
icing
conditions
or
flights
in
any severe
icing conditions.
Flight in these
conditions
must
be avoided.
Even airplanes fully equipped and
certified
for flight
in the icing conditions described in
Appendix
C to
FAR Part 25
must avoid flights into those conditions
defined by the National Weather Service
as
10-28
