| Improved accuracy of ground-based trajectory prediction is often regarded as one of the key enablers to deliver improvements in terms of safety, capacity and efficiency in Air Traffic Management (ATM). As a solution, there is an increased focus on the use of trajectory information available from an aircraft?s Flight Management System (FMS). This paper presents a methodology and structure for ground-based trajectory predictors to integrate information down-linked from an FMS. By appropriately combining information available from ground-based sources and the FMS, the impact of the aircraft guidance strategy on the trajectory can effectively be incorporated in the ground-based prediction. Results from a case study performed on arrival trajectories into Melbourne, Australia, demonstrated up to 32% reduction in the standard deviation of Estimate Time of Arrival errors compared to the original FMS predictions when the proposed methodology is applied. While it is often regarded that the most accurate prediction of an aircraft?s trajectory is sourced from the FMS, the results in this paper demonstrate that when the proposed methodology is applied, it is in fact a ground-based trajectory predictor that can compute the most accurate trajectory. | |
