Transmission among aeronautical systems and ground stations are of a major importance for numerous operational configurations. The International Telecommunication Union (ITU) officially recommends a model mainly based on the IF-77 electromagnetic wave propagation model. However, French team at ITU showed some drawbacks of the proposed model related to ITU recommendations P.525 and P.526 for areas of high reliefs. In this talk, we summarize key ideas in the IF-77 model and potential problems of using only single-knife edge diffraction in the model. We then propose several approaches to tackle this problem. We conclude this talk by discussing several research directions we aim to conduct in a future work.
