A robust, high-fidelity and complete dataset is a vital component in supporting the safe, efficient and effective flow of air traffic through various airspaces and aerodromes. Support tools and enhanced situational awareness requirements necessary to meet these needs are increasing the demand for data, in particular, reliable, real-time position of aircraft beyond the Flight Information Region (FIR) and the time at which these aircraft will enter the FIR or arrive at an airport.
