Abstract:

This reports documents the Federal Aviation Administration FAA data collection and analysis effort to investigate Secondary Surveillance Radar SSR problems encountered at the Chicago OHare Terminal Approach Control TRACON facility. The FAA has mandated the implementation of Traffic Alert and Collision Avoidance System TCAS II to the entire air transport fleet by December 31, 1993. To provide for the smooth and orderly implementation of TCAS II, the TCAS Transition Program has been established to accomplish these objectives. The FAA Technical Center Research Directorate for Aviation Technology, ACD-320, conducted the investigation by developing the data collection system capability of the Data Link Test and Analysis System DATAS. Two distinct capabilities were developed to monitor the uplink and downlink activity of the SSR system frequencies. The uplink data collection system is an airborne installation of DATAS on an FAA aircraft and test flights were conducted to obtain the uplink data. The downlink data collection system was installed at the ground radar facility to monitor the Air. Traffic Control Radar Beacon System ATCRBS receiver signal for downlink analysis. Data results and analysis of both efforts are documented herein.
