In the highly expandable air transport industry, in order to design airport obstacle free areas, several design criteria must be looked in carefully. The most important components of these criteria are: size of airport, length and width of runway, runway shoulder, safaty area, stop way area,and dimension of clear way, including; horizontal surface, conical surface, approach surface, and transitional surface.Since high rise building and towers have always created problems for airport designers, in this research a mathematical and computerized model has been developed to resolve these diffuculties. The application of the developed model covers various categories of airports.The methodology of research is such that all the obstacles surrounding the runway are controlled, in this way no point will be considered as an obstacle towards these surface. Should there be any obstacle, a solution will be recommended to resolve the problem.The aim of this research is to design a runway free from any obstacle either natural or manmade. The standard code of practice used for this software complies with the documents of International Civil Aviation Organization (ICAO). The developed software operates on Win 98 platform based on Visual Basic 6.
