This technological solution provides more timely and accurate wind information, derived from the downlink of mode S data from aircraft in the approach, to be integrated into the air traffic management (ATM) system (PJ.02-01-01 optimised runway delivery), enabling more accurate and precise calculated spacings between consecutive arrivals on the final approach. 

The derivation process consists in comparing the movement vector of an aircraft to the true north-oriented vector and adjusting precise magnetic variations. this calculation is repeated for each consecutive arrival with pre-filtered mode S readouts while the outcome is used to build a vertical profile of winds aloft along the approach path.
