In recently released details for its Performance-Based Navigation (PBN) strategy for the airspace above the U.S., the FAA has provided insights into the how it will make necessary system changes, in addition to why. PBN defines the accuracy, availability and integrity of the satellite signals used to create the nation’s future navigation system by eliminating ground-based navaids and focusing on satellites for guidance.
FAA Releases Navigation Strategy for the National Airspace System
Key Takeaways:
- The FAA's Performance-Based Navigation (PBN) strategy for U.S. airspace aims to shift guidance from ground-based navaids to satellite signals, defining their accuracy, availability, and integrity.
- A core component of the PBN strategy is ensuring resilient navigation capabilities that can continue to function even if GNSS (satellite) signals are interrupted by external conflicts or natural disasters.
- The FAA has outlined four guiding principles for PBN implementation, focusing on procedure, structure, air traffic management shift, and resilient services, though critics note an extended completion timeline.
