To indicate the capability of windshield anti-ice is adequate under all combinational cases of flight en-velope and icing condition. ,the design requirement and flow field characteristics of windshield is analyzed ,a theo-retical conservative engineering model of windshield anti-ice thermal analysis was established. Key coefficient of the model was corrected and verified by flight test data. The model can be implemented by general programming language or EXECL internal function to deal with thermal analysis under all combinational cases. The results could support airworthiness certification or filter CFD cases.
