A Real-Time ETA-to-Threshold Prediction Tool

This paper presents the results from the development of a procedure and algorithms for the real-time estimation of aircraft arrival times (ETA-aloft) at the runway threshold. The prototype was developed with extended range (90-110 nmi) multilateration data measured at Lambert-St. Louis International (STL) Airport. Model development and calibration was based on data collected in April 2005; validation was performed with data collected in February 2005. The model is based on airspace region characteristics, is analytical in nature, and is based on commonly-available data (e.g., aircraft position, runway properties, navaids)
