Equipped to fly to within an accuracy of one nautical mile (NM), modern aircraft have the capability to follow very flexible routes, for example reducing noise impact on populated areas and easing bottlenecks. This navigation capability is especially useful in busy terminal airspace, where the increased accuracy allows more approach paths, which can release capacity, reduce holding and cut emissions.
Solution #62 "Precision area navigation (P-RNAV)in a complex terminal airspace" introduces precision area navigation (P-RNAV) procedures that improves the design and organisation of the airspace allowing the aircraft’s on-board navigation system to fly optimised flight paths.
This SESAR solution #62 is now implemented in Madrid and a few others airports.
