Abstract:

AN INVESTIGATION ABOUT EVALUATION OF ICING ON AIRPLANES AND DE-ICING SYSTEMS ON PROPELLER AIRCRAFTS (M.Sc. Thesis) Aytekin ÇAKICI GAZI UNIVERSITY INSTITUTE OF SCIENCE AND TECHNOLOGY July 2005 ABSTRACT Icing is one of most serious meteorological hazards in aviation operations since it renders aircraft unflyable before flight and severely reduces aircraft performance during flight. Environmental factors like altitude, climate conditions, humidity, and temperature are important factors for severity of icing conditions. Since icing occurs most frequently at lower altitudes and slower airspeed it induces remarkably more vulnerability and greater negative impact on propeller fixed wing aircraft that fly slowly and low or medium altitude. In addition to hazards that can be encountered during flight, forecasted icing conditions cause mission delays due to preventative ground deicing operations, and mission cancellations. To completely avoid from the probable risks that are resulted from icing conditions, some flight missions are aborted after mission already has begun. Scope of this report is limited to propeller fixed wing aircraft and their crew. Different flight conditions, protection capabilities of de-icing and anti-ice systems, aviation safety messages and historical data of past accidents have been analyzed. Previous worldwide studies about icing effects on aviation and necessary precautions are also briefed. In the report, effects of prior and during flight icing on the ability of aviators and aircraft are investigated and assessed. Interviews and surveys with aviators and aviation organization leaders, andVI graphical methods are used as tools to demonstrate the affect of icing on flight operations. In conclusion, this study will provide contribution to enhance safety of flight operations including training of all aviators and taking necessary precautions in aviation organizations.
