Wind Rose

Complete the following exercise for your airport inventory using the data on your FAA Form 5010, your inventory data, and the historical wind data provided by the instructor. Refer to Advisory Circular 150/5300-13A Appendix 2. When planning a new runway, or evaluating the need for a crosswind runway, airport planners start by conducting a wind analysis. A wind analysis is the formal method used to ensure runways are aligned with the prevailing winds. The process starts by obtaining historical data from NOAA and plotting it on a wind rose. Appendix 2, Wind Analysis, of FAA Advisory Circular 150/5300-13A outlines the procedure for you. Then, you can evaluate an existing runway, or determine the best orientation of a new runway. This assignment consists of a series questions about your wind analysis, creating a wind rose, and summarizing your analysis and findings in a narrative report for a section in your Airport Master Plan. The details are included in the attached files. Please use the wind data provided as your historical data. 1. How many observations are included in the historical wind data? 2. What is the orientation and width of the primary runway at your airport? 3. What is the Runway Design Code (RDC) for your airport and what is your maximum allowable crosswind component? 4. What is the minimum desired wind coverage for an airport? 5. Using your maximum crosswind component and the wind data provided, create a wind rose to calculate the wind coverage for your existing primary runway. 6. What is the optimum runway orientation for your airport? Deliverables for this assignment: 1. Complete this questionnaire. 2. Create a wind rose for your primary runway. Include all calculations: wind direction vs wind speed conversion to percentages, completed wind rose with runway alignment, and “estimated area not included” calculation. 3. If your runway does not provide the required wind coverage, what can be done to ensure your airport complies in the future? 4. Provide a narrative based on this exercise. Document all assumptions and outcomes. The procedure is as follows: 1. 1) Choose design aircraft in your airport’s fleet mix based on reasonable assumptions. Determine Runway Data Code (RDC) based on Aircraft Approach Category (AAC) and Airplane Design Group (ADG) for the design aircraft. Identify maximum allowable crosswind and choose appropriate template. 2. 2) Convert data observations to percent (share for each condition) 3. 3) Find magnetic variation at your airport. 4. 4) Realign compass points to align your runway adjusted for the magnetic variation 5. 5) Populate wind rose with percent occurrence for each condition (dir/kts) 6. 6) Calculate percent coverage (probably easier and acceptable to calculate area not covered and subtract from 100%)
