The
Normal
Procedures Section
of
the AFM by incorporating the
following:
THE
FOLLOWING
WEATHER
CONDITIONS
MAY
BE
CONDUCIVE
TO
SEVERE
IN-FLIGHT
ICING:
• Visible rain
at
temperatures below 0 degrees Celsius ambient air
temperature.
• Droplets that splash or splatter on impact
at
temperatures below 0
degrees Celsius ambient
air
temperature.
PROCEDURES
FOR
EXITING
A
SEVERE
ICING
ENVIRONMENT:
(These procedures are applicable
to
allflightphases
from take-off
to
landing.)
Monitor
the
ambient
air
temperature.
While severe icing may form
at
temperatures
as
cold
as
-18
degrees
Celsius, increased vigilance is warranted
at
temperatures around freezing
when visible moisture is present.

Immediately request priority handling from Air Traffic Control to
facilitate
a
route
or
an
altitude
change
to
exit
the
severe icing
conditions in order
to
avoid extended exposure
to
flight conditions
more severe than those for which the aircraft has been certificated.
Avoid
abrupt and
excessive
manoeuvring
that
may exacerbate
control difficulties.
Do not engage the autopilot.
If
the autopilot had previously been engaged, hold the control wheel
firmly and disengage the autopilot.
If
an
unusual
roll
response
or
un-commanded
roll
control
movement
is
observed, reduce the angle-of-attack.
Do
not extend flaps when holding in icing conditions. Operation
with flaps extended can result
in
a reduced wing angle-of-attack,
with the possibility
of
ice forming on the upper surface further aft on
the
wing than normal, possibly aft
of
the protected area.
If
the flaps are extended,
do
not retract them until the airframe is
clear
of
ice.
• RepOli these weather conditions
to
Air Traffic Control.
If
the visual cues which
are
specified
in
the Limitations Section
of
the
AFM for identifying severe icing conditions are observed, accomplish the
following:
