Test and Evaluation of the Accuracy Capability of the Aircraft Separation Measurement System for Application as a Measurement Facility

摘要

Basic system accuracy of the Aircraft Separation Measurement System was evaluated. Two NAFEC aircraft were flown in various flight patterns during which ASMS-derived aircraft separation measurements were recorded in one of the aircraft on a digital printer. Paired phototheodolite stations tracked the aircraft and provided time-correlated aircraft coordinates which were converted into comparable reference aircraft separation data. Comparison of ASMS and phototheodolite data demonstrated an average ASMS system error of 0.017 nautical miles (103 feet), with standard deviation of 0.026 nautical miles (158 feet). (Author)
