Flight into severe icing conditions
Severe icing conditions, particularly freezing rain and freezing drizzle, can be
identified by :
-
unusually extensive ice accumulation on the airframe and windshield in
areas not normally observed to collect ice,
-
accumulation of ice on the upper surface of the wing aft of the protected
area.
Procedures for exiting freezing rain or freezing drizzle conditions :
1 -
Inform ATC to exit severe icing conditions by changing the route or the altitude.
2 -
Avoid any sudden maneuver on flight controls.
►
Do not engage the autopilot
◄
If the autopilot is engaged :
3 -
Hold the control wheel firmly and disengage the autopilot.
If an unusual roll response or uncommanded roll control movement is observed :
4 -

►
Do not extend flaps when holding in icing conditions
◄
Operation with extended flaps 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 :
5 -
Do not retract them until the airframe is clear of ice.
End of procedure.
