Aircraft icing can be defined as the process of changing the state of concentration of water contained in the air in the form of nanoparticles into a solid form accumulating on the surface of aircraft construction elements during a flight or results from the direct accumulating of ice crystals on the aircraft surface. The icing process of the airframe surface, including wings, occurs in the favorable atmospheric conditions, which depends on many factors. One of the basic factors affecting the occurrence of wings airfoil icing phenomenon are the flight parameters of the aircraft. This article presents the results of numerical simulation tests of the developed wing model on the basis of measurements of the Cirrus SF50 Vision Jet aircraft real wing geometry. Based on the results of numerical simulations, a model for identifying conditions conducive for the wing icing process was developed depending on the flight parameters of the aircraft. The developed model can be used as a diagnostic tool to detect conditions conducive to aircraft airframe surface icing process, and to determine flight parameters that reduce the risk of a phenomenon occurring in given atmospheric conditions.
