The initial trajectory information sharing solution is based on the aircraft downlinking trajectory information directly from the FMS to the ground systems via an updated standard for the automatic dependent surveillance contract (ADS-C) that is used today exclusively for oceanic and remote operations. The newly developed standard is called ATN Baseline 2 and targets all operations. It allows the i4D FMS to downlink the extended projected profile (EPP), which contains an updated FMS route prediction. The data in the new standard is much more detailed than in the current ADS-C reports used in oceanic airspace; it includes, for example, the predicted aircraft weight, as well as the predicted horizontal and vertical speeds on up to 128 future waypoints along the route.
In this initial solution, the ground systems will enable controllers to display the downlinked route on the radar screen and will also automatically cross-check whether the downlinked route is consistent with what was expected on the ground; controllers will receive a warning in case a discrepancy is identified.
This solution is ready for industrialisation. It will be deployed in a synchronised way across 22 air traffic control centres and 18 terminal manoeuvring areas and airports across Europe in accordance with the Pilot Common Project.
