PBN enables airspace users to fly more predictable flight paths, enhancing safety and capacity, and reduce environmental impact. PBN routes are available across much of European airspace, and are being increasingly introduced in busy terminal environments. SESAR is working on using the technology to provide simultaneous approaches to two parallel runways in high density and complex environments. The candidate solution includes developing PBN transitions, which connect to the final approaches, and PBN route structures which facilitate path stretching or shortening. SESAR is also addressing the impact on flight crew tasks, controller workload, and overall feasibility.
The candidate solution covers independent parallel approaches where PBN is used to increase segregation of arrival flows to the parallel runways, and to ensure a standard interception of the extended runway centreline. It relies on pre-defined trajectories with higher vertical profiles prior to final approach and the application of RNP navigation specifications. The candidate solution addresses two options to join the PBN transitions: merging to a point or merging to an axis.
The candidate solution is expected to result in safer approach paths and, once safety targets are met, support airspace capacity increase as a result of path stretching or shortening. It also reduces environmental impact by enabling aircraft to follow more optimal vertical profiles.
