Abstract
This action revises the operating rules for flight in icing conditions. For certain airplanes certificated for flight in icing, the new standards require either installation of ice detection equipment or changes to the airplane flight manual to ensure timely activation of the airframe ice protection system. This action is the result of information gathered from icing accidents and incidents. It is intended to increase the level of safety when airplanes fly in icing conditions.
