BIG DATA HELPS PREDICT FLIGHT ARRIVALS WITH GREATER ACCURACY

Airport arrivals can become constrained as a result of wake vortex separations, wind conditions and high runway occupancy. SESAR is developing a more efficient separation delivery tool for arrivals to support complex separation rules at capacity-constrained airports.

The enhanced optimised runway delivery (eORD) tool is based on more accurate predictions of final approach speed profiles derived from either an evolved eFPL, extended projected profile (EPP) down-linked from aircraft using ADS-B or advanced machine learning (ML) techniques. eORD may also benefit from advanced meteorological sources, including SWIM METforWTS service, to gain more accurate and reliable wind nowcasts and forecasts on the final approach which could also be used to better predict aircraft speed profiles.

The more accurate predictions of final approach speed profiles will be used to more accurately determine the spacing that needs to be delivered at the deceleration fix (DF) in order to achieve the required separation and spacing at the separation delivery point.

This more accurate spacing and separation delivery will lead to further reduced spacing between consecutive arrivals for the majority of aircraft pairs. Overall, the eORD tool will lead to a benefit in terms of increased runway throughput capacity due to the reduced, optimised separation and spacing on the final approach.  As the separation and spacing are based on more flight-specific behaviour/performance and as a result are better tailored per aircraft pair, there is a potential positive impact on safety.
