Performance-Based Navigation (PBN)

Performance-Based Navigation (PBN) is an advanced air navigation system that allows aircraft to follow precise routes using satellite-based navigation and onboard systems, rather than relying solely on ground-based radio aids. This technology improves route accuracy, efficiency, and safety by enabling aircraft to fly more direct paths and operate in more challenging environments with less infrastructure. PBN enhances overall airspace capacity, reduces fuel consumption and emissions, and allows for more flexible routing, especially in crowded or remote areas. It represents a modern approach to navigation that optimizes flight operations through proven performance capabilities.
