Method for identifying optimum runway orientation

A method applied with computer comprising a database, a control unit, a data input interface, a user interface and a display for allowing identification of the optimum runway orientation that produces the highest usability factor by using an electronic device, wherein the method is characterized with the steps set forth hereunder, in its most basic form;

• determining the total number of observations by retrieving the wind data from the database,
• obtaining the permissible maximum cross-wind value over the data input interface,
• forming a runway template based on the permissible maximum cross-wind value for that plane by considering the smallest aircraft size that might land on the runway,
• Automatically rotating the runway template on a wind rose with 10° intervals starting from the true north,
• calculating the usability factors by evaluating the wind observations covered by the runway template for each shift in wind direction by 10° individually,
• Making inquiry about whether the calculated usability factors are higher than a threshold value,
• If the usability factor is higher than the said threshold value, then terminating the analysis and displaying the calculated usability factor and the runway orientation associated with such usability factor, in terms of degrees, on the display.
