This Traffic Control and Landing System (TRACALS) evaluation was performed to define the capabilities and limitations of the AN/FPN-62, Precision Approach Radar (PAR), at Hill AFB, Utah in its installed environment. The evaluation included a comprehensive examination of the PAR siting, equipment technical order (TO) parameters, system operational performance, effects of weather, and aircraft flight verification of the 1881 Communications Squadron (CS) mission requirements. The AN/FPN-62 PAR is fully capable of providing required PAR approaches to Runway 14 at Hill AFB. It is capable of detecting a C-140/F-16 size aircraft at 15 nautical miles (NM) and an A-7 size aircraft at 13 NM in Normal video with the RF GAIN switch in the HIGH position while in circular polarization (CP). These ranges will be approximately 3 NM less with the RF GAIN switch in the low position while in CP. In linear polarization (LP), radar range should be approximately 15 NM. Local weather conditions may influence the system capabilities. Intense rain may cause a decrease in the detection range of the system, even when it is in the CP mode. Severe subrefractive conditions may shorten the range at which an aircraft can be detected, while simultaneously raising the glidepath angle.
