The SJU recently published a number of research papers on trajectory based operations (TBO), a cornerstone concept of the SESAR Research and Innovation Programme. These papers were presented at recent meetings of the ICAO working group of the Air traffic Management Requirements and Performance Panel, feeding discussions at a global level, ultimately leading to a globally harmonised and interoperable TBO concept. While SESAR’s results continue to increase the overall predictability of trajectories, on top of that the TBO concept defines how capacity or weather-constrained trajectories can continuously be “optimised” and coordinated in an iterative dynamic way, taking into account the remaining level of unpredictability. The papers build on SESAR’s validation results and places these results in the wider TBO context
