"THE FOLLOWING WEATHER CONDITIONS MAY BE
CONDUCIVE TO SEVERE IN-FLIGHT ICING"
Visible rain at temperatures below O degrees Celsius ambient air
temperature.
Droplets that splash or splatter on impact at temperature below O degrees
Celsius ambient air temperature.
"PROCEDURES FOR EXITING THE SEVERE ICING
ENVffiONMENT"
These procedures are applicable to all flight phases from takeoff 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 with visible moisture present.
If
the visual cues
specified in the Limitations Section of the AFM for identifying severe icing
conditions are observed, accomplish the following:
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 airplane has been certificated.
Avoid abrupt and excessive maneuvering that may exacerbate control
difficulties.
Do not engage the autopilot.
If
the autopilot is engaged, hold the control wheel finnly and disengage the
autopilot.
If
an unusual roll response or uncommanded 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.
V
Report these weather c9nditions to Air Traffic Control.
