The runway orientation is the result of compromises between the airport usability and additional factors, such as available land, existing bstructions, topographic difficulties, flight path interference, noise pollution and other environmental impacts. Therefore, the solution of a combination of acceptable orientations, which avoids excessive crosswinds at least 95% of the time, as well as the optimal orientation, is essential to conduct those compromises in the runway orientation analysis. The objective of this paper is to develop a computer model which is capable of providing a combination of acceptable runway orientations, changing the allowable crosswind limit flexibly, and determining the optimal orientations of two runway configurations. Instead of visual estimation or geometric computation, this paper presents a probabilistic method for wind coverage analysis, which is running in spreadsheet and VBA. The numerical example and comparison show that the model is competitively accurate and improved convenient in comparison with previous ones.
