icing conditions

icing conditions

Weather conditions conducive to the formation of ice on an aircraft in flight. These conditions are usually characterized by visible moisture in the air and temperatures around the freezing level (i.e., +2° to −10°C). Pilots encountering icing conditions are urged to issue a pilot weather report (PIREP) immediately.
