Elements of PBN Concept - Navigation Specification - International Navigation Specifications published in Volume II of PBN Manual Aim is to limit number of Nav. Specs in global use What PERFORMANCE is required of the RNAV system? What Functionalities must RNAV system have to achieve Performance What Navigation Sensors must be integrated in RNAV system to achieve Performance What requirements are placed on the Air crew to achieve the required Performance from the RNAV system? Accuracy Integrity Continuity Availability NAVIGATION SPECIFICATION 2 3 Document used by State as basis for developing Certification & Operational Approval

Elements of PBN Concept - Navigation Specification - RNAV RNP On-Board performance Monitoring and Alerting On-board performance monitoring and alerting does not only refer to ‘containment’ in the MASPS; Annex 11 or PANS-OPS. On-board performance monitoring and alerting allows the air crew to detect that the RNAV system is not achieving the navigation performance required of the RNAV system

Why Change to PBN? Proliferation of national standards PERFORMANCE Functionalities Navigation Sensors Air crew requirements Previous RNP Concept Proliferation of national standards Wide variety of functional requirements Variety of required navigation sensors Differing air crew requirements Lack of global harmonsiation Publication of PBN navigation specifications seeks to limit number of certification standards

PBN BENEFITS Reduction to number of sensor-specific routes Allows more efficient use of airspace Clarifies how RNAV systems are to be used Facilitates operational approval process for operators by providing limited set of navigation specifications intended for global use Provides potential to exploits capabilities of advanced RNAV systems Enables navigation applications for Terminal Airspace
