Abstract : The report describes operational testing conducted to evaluate the functional capability, operational utility, and system reliability of the Direct Altitude and Identity Readout (DAIR) beacon numeric decoding and display system. Operational testing was essentially a dynamic simulation effort, using a representative terminal facility/geographic air traffic control environment. Test data were obtained from recordings of measurable controller workloads, system performance, and subjective comment from all project participants. Comparative tests were conducted between present-day FAA and DOD passive beacon decoding systems and the DAIR system active readout. Quantitative results were statistically analyzed to obtain any significant differences between the systems tested. Controller comments and opinions were recorded and summarized for presentation as subjective results. Special tests were conducted to obtain controller opinion regarding the use of the DAIR-derived center mark as a separation resolution factor, and the effect of the DAIR presentation with regard to certain secondary radar phenomena. Results of the operational testing indicated that the DAIR system was functionally sound. Operational utility and application of the active beacon numeric readout were desirable and enhanced operations in the tested environment. (Author)
