On 18 October EUROCONTROL announced that PBN-based procedures support more flexible route placement and take advantage of precise trackkeeping capabilities on board modern aircraft. In addition to the safety benefits associated with advanced navigation, PBN creates shorter flight paths and provides the opportunity to avoid populated areas.

This is also beneficial to the environment, as introducing multiple PBN arrival routes can serve to disperse noise emissions across a wider area, while steeper approaches and increased climb gradient could also help to reduce greenhouse emissions.
