Required Actions
Revise the AFM's Limitations and Normal Procedures sections to prohibit flight in severe icing conditions (as determined by visual cues), limit autopilot use when ice forms aft of protected wing surfaces or if unusual lateral trim occurs, and provide flight crew with recognition cues and exit procedures for severe icing conditions.
