Establishment Criteria for Integrated Wind Shear Detection Systems: Low-LevelWind Shear Alert System (LLWAS), Terminal Doppler Weather Radar (TDWR), and Modified Airport Surveillance Radar

摘要

This report presents an integrated, site-specific, benefit-cost analysis of threewind 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-APO's 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.
