Hazards Following Ground Deicing and Ground Operations in Conditions Conducive to Aircraft Icing

The purpose of this report is to emphasize the Clean Aircraft Concept following ground operation in conditions conducive to aircraft icing and to provide information to assist in compliance. Recent accidents involving large transport and small general aviation aircraft indicates that misconceptions exists regarding the effect of slight surface roughness caused by ice accumulations on aircraft performance and flight characteristics and the effectiveness of Freezing Point Depressant FPD ground deicing and anti-icing fluids. During development of information contained herein it was recognized that guidance information should be directed to all segments of aviation to include aircraft manufacturers airline engineering, maintenance, service and operations organizations aircraft maintenance and service personnel and aircrews of all aircraft types and categories. Information contained herein therefore is general in nature for basic understanding purposes to facilitate development of standardized procedures and guidance by various segments of the aviation industry.
