In this paper, the electromagnetic propagation coverage of different VOR stations over irregular terrain airport locations has been presented. Three different investigation studies for different airports in the heavy terrain red sea area are introduced. The calculation has been done applying Longley rice propagation model. The theoretical calculation concepts of the employed electromagnetic propagation model are discussed. The coverage areas for the two studied air ports were plotted using digital Two dimensional geographical maps with 90 meter resolution. The results are compared to standard line of sight model.
