Performance Based Navigation Initiatives

The FAA is supporting the use of Performance Based Navigation (PBN) to provide greater flexibility in the National Airspace System (NAS) and to facilitate more dynamic management of air traffic. PBN is valuable as it provides a framework for defining performance requirements in navigation specifications that contain detailed aircraft and operator/pilot requirements. It further provides a basis for the design and implementation of air traffic routes and instrument procedures and also can support airspace design requirements. The FAA is conducting key activities to support the use of PBN.

Optimization of Airspace and Procedures in the Metroplex

Optimization of Airspace and Procedures in the Metroplex (OAPM) is a systematic, integrated and expedited approach to implementing PBN procedures and associated airspace changes to improve descent efficiency, increase diverging departure paths and reduce coupling of operations among airports in metroplex airspace. (See video).

This project is focused on operational optimization, delivering key efficiencies for the nation's busiest metropolitan areas within 2-3 years once work begins at each site. Improvements at 13 metroplex sites are expected to be implemented by 2017.

Additional PBN Development

Beyond work to improve the flow of traffic in metroplex areas, the FAA is developing and implementing PBN procedures in other areas of the country.

Third Party Vendor PBN Development

The FAA has enlisted the assistance of a third-party vendor to supplement the agency's development of PBN procedures for airports across the country. ITT-GE Aviation is designing and will be implementing and maintaining ten required navigation performance procedures, two each at five airports: Anchorage, Dayton, Buffalo, Milwaukee and Syracuse. The FAA will closely monitor the work to make sure all safety and environmental steps are conducted properly.
