Abstract A novel $$\Delta $$-model approach to characterize the changes in longitudinal and lateral aircraft dynamics occuring due to local icing is analytically derived. This model extension is formulated as a separate module in the aircraft flight mechanics simulation and can be used in existing simulation models. Using the former DLR research aircraft VFW 614 ATTAS as example, information about the icing-induced performance and handling degradation is obtained by 3D CFD calculations with numerically generated ice shapes. With the resulting data, $$\Delta $$-model parameters describing a local aerodynamic degradation are estimated. Simulation of the local wing icing influences on the aircraft’s dynamic behavior show the $$\Delta $$-model’s capabilities to cover aerodynamic changes during a de-icing process.
