Performance-based navigation offers a number of advantages over the sensor-specific method of developing airspace and obstacle clearance criteria. 

For instance, PBN:

  1. reduces the need to maintain sensor-specific routes and procedures, and their associated costs. For example, moving a single VOR ground facility can impact dozens of procedures, as VOR can be used on routes, VOR approaches, missed approaches, etc.
  2. avoids the need for development of sensor-specific operations with each new evolution of navigation systems, which would be cost-prohibitive.
  3. allows for more efficient use of airspace;
