This report presents an integrated, site-specific, benefit-cost analysis of three wind shear detection systems the low-level wind shear alert system LLWAS, terminal doppler weather radar TDWR, and airport surveillance radar modified for wind shear detection. Based on this analysis, a benefit-cost investment decision model has been developed. This investment decision criteria model will be incorporated into FAA-APOs Aviation Data Analysis ADA System. Application of the establishment criteria documented in this report will enable the FAA to prioritize alternative investments among wind shear detection equipment types as well as sites, so as to maximize the return on investment dollars. For purposes of APS-1 criteria, FAA toward airports with a net present value NPV of zero or greater for a particular wind shear detection system will be considered establishment candidates for that system. If more than one system yields an NPV greater than or equal to zero at a particular site, then the one with the highest positive NPV is recommended for that site.
