Performance Based Navigation

Improvements in aircraft navigation performance provide an opportunity to increase efficiency and flexibility. The Performance Based Navigation aviation portfolio addresses ways to leverage emerging technologies, such as Area Navigation and Required Navigation Performance, to improve access and flexibility for point-to-point operations.


  • Access

    Provides an operating environment ensuring all airspace users have right of access to the air traffic management resources they need to meet their specific operational requirements, and the shared use of airspace by different users can be achieved safely. The global air traffic management system should ensure equity for all users that have access to a given airspace or service.

  • Efficiency

    Addresses the operational and economic cost-effectiveness of gate-to-gate flight operations from a single-flight perspective. In all phases of flight, airspace users want to depart and arrive at the times they select, and fly the trajectories they determine to be optimum.

  • Flexibility

    Ensures the ability of all airspace users to dynamically modify flight trajectories and adjust departure and arrival times, thereby permitting them to take advantage of operational opportunities as they occur.

  • Predictability

    The ability of airspace users and air traffic management service providers to deliver consistent and dependable levels of performance. Predictability is essential to users as they develop and operate their schedules.
