【 摘 要 】

Ice accretion on a wing is one of the aviation accident factors because it will interrupt the flow over an airfoil that will reduce its performance. The effect of wings leading edge ice accretion on the landing distance of commuter class aircraft in remote high terrain operation was obtained with the help of LEWICE code for ice shape predictions and XFLR5 for airfoil polar data prediction. The ice accretion process occurred within various icing atmospheric conditions based on Icing Design Envelopes 14 CFR part 25.1419, Appendix C. Two category of ice accretion, horn ice and streamwise ice, were obtained on the leading edge of the wing. The performance degradation caused by the ice accretion will increase aircraft landing speed that it will affect the landing distance.
