The project will analyse the performance of Extended Projected Profile (EPP) information from multiple live trials involving aircraft equipped with prototypes of the next generation flight management system (FMS) and data link communication systems. Along with additional information, the EPP is a sequence of geographical waypoints that an aircraft will fly over, together with times when the aircraft will pass these waypoints. The EPP is a core element of the SESAR i4D concept in which trajectories are synchronised between air and ground, thus enabling increased predictability of air traffic. Through live flight trials across high density continental airspace, the project will aim to show that the EPP information regarding the trajectory flown is accurate and reliable and that the sharing of this information improves the performance of the systems on the ground, as well as in the air.
