MANUAL
FUNCTIONAL
TEST Of FLIGHT
CONTROLS
In
a
case
where
an
airplane
has
been
extremely
iced
or
snow
covered,
a
flight
control
check
should
be
performed.
This
check
should be
repeated
after
deicing/anti-icing.
CHECK
OF ENGINE
INLETS
AND
PROBES
Engines
that have been
exposed
to
heavy
snowfall
and/or
freezing
rain
during
cold
temperatures
and
strong
winds
must
be
checked
prior
to
start-up
for
accumulation of
snow
and/or
ice
in
the inlet and
exhaust
areas.
DNCING
AND
ANTI-ICING
FLUIDS
All
approved Type
I
fluids
may
be
used
for either
deicing
or
anti-icing
at
any
dilution
as
allowed
by
the fluid
manufacturer’s
recommendations.
Raytheon
Aircraft
Company
has evaluated
and
approved
the
following
deice/anti-ice fluids:
TYPE I FLUID
PER
SAE
AMS
1424
AND
ISO
11075.
UCAR
ADF
Concentrate
UCAR
ADF
50/50
Arcoplus
Kilfrost
DF
SAE
Type
I
Anti-icing
Fluids
(Unthickened-Type
Fluids)
provide
protection
against refreezing
when there is
no
precipitation
These
fluids
are
authorized
for
use
on
Baron
55
and
58
airplanes.
NOTE:
Raytheon
Aircraft
Company
cannot
accept
responsibility
for
damage
to
the
airplane
finish,
windows,
rubber
seals,
etc.
resulting
from
the
use
of
deicing
fluids
produced
by
other manufacturers.
These fluids
were
chosen
according
to
the
following
specifics:
a.
Noncorrosive.
b.
Do
not
deteriorate
rubber,
painted
surfaces,
or
plastics.
c.
Have
a
high
flash
point.
d.
Nontoxic.
e.
Good
self-wetting
and
antifoaming
characteristics.
These
deicing
fluids
are
specially
inhibited,
glycol-based
solutions that
leave
a
fairly
tough,
viscous
coating
on
the
surface. Each
drop
is
capable
of
absorbing
at
least its
own
weight
of
water.
While
the fluid
remains
liquid,
snow
and
ice
will
not
adhere
to
the skin. This
protection
will
remain
until the fluid becomes
overly
diluted
by
falling
snow
and
freezing
rain.
Once
the fluid
becomes
overly
diluted,
it
may
begin
to
freeze.
A
visual
inspection
is
not
always
a
good
indicator
of
the
fluid’s current
state.
A
tactile
inspection
is
the
best
way
to
determine the
current
condition
of
the
anti-
icing
fluid
application.
