What does PBN stand for in aviation navigation?

Performance-Based Navigation (PBN) is a critical concept in aviation that refers to navigation systems and procedures that rely on the performance capabilities of aircraft, rather than on ground-based navigation aids. PBN allows aircraft to fly more precise flight paths using advanced satellite and onboard navigation systems.

In particular, PBN encompasses various navigation specifications such as Area Navigation (RNAV) and Required Navigation Performance (RNP), which enable pilots to navigate more efficiently and accurately in complex airspace. By focusing on the aircraft's performance capabilities, PBN enables the optimization of flight routes, leading to improved safety, efficiency, and environmental sustainability in air travel.

Understanding PBN is vital for pilots and aviation professionals as it shapes modern air traffic management and influences the design and implementation of airways and approach procedures.
