During flight, severe icing conditions that exceed those for which the airplane is
certificated shall be determined by the following visual cues. If one or more of these
visual cues exists, immediately request priority handling from air traffic control to
facilitate a route or an altitude change to exit the icing conditions.
-
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.
Since the autopilot, when operating, may mask tactile cues that indicate adverse
changes in handling characteristics, use of the autopilot is prohibited when any of the
visual cues specified above exist, or when unusual lateral trim requirements or
autopilot trim warnings are encountered while the airplane is in icing conditions.
All wing icing inspection lights must be operative prior to flight into icing conditions at
night.
