NTSB Recommends Icing Precautions in Pilot Handbooks

The National Transportation Safety Board has issued a recommendation directing the Federal Aviation Administration to require that all pilot operating manuals and airplane flight manuals applicable to aircraft certified for flight in icing conditions contain specific precautionary operational information. This guidance is intended to help ensure that ice does not accumulate on the underside of the wing aft of the area protected by deicer boots or on other unprotected areas of the airplane. The recommended information must include the specification of a minimum indicated airspeed that should be maintained during sustained operations in icing conditions.
