Thin Margins in Wintry Takeoffs

摘要

For many years the application of the "clean wing policy" has successfully allowed aircraft to take off when conditions are conducive to icing. While anti-icing fluids negate the serious effects of wing icing, recent research has determined that the fluids themselves extract a significant penalty from the wing's aerodynamic capabilities, especially from high-performance wings commonly on jets that cruise at transonic speeds. The effect is manifested most during the takeoff rotation.
