  3. 3 NAVIGATION APPLICATION NAVIGATION SPECIFICATION 2 NAVAID INFRASTRUCTURE 1 Elements of PBN Concept 3 1 2

  4. Elements of PBN Concept- Navaid Infrastructure - • Ground-based Navigation Aids (Navaids) • VOR; DME; (Not NDB) • Space-based Navaids • GNSS • GPS; Glonass; futureGalileo NAVAID INFRASTRUCTURE 2 1

  6. 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 3 2 Document used by State as basis for developing Certification & Operational Approval

  7. International Navigation Specifications published in Volume II of PBN Manual • PERFORMANCE • Functionalities • Navigation Sensors • Air crew requirements Previous RNP Concept NAVIGATION SPECIFICATION 3 2 Document used by State as basis for developing Certification & Operational Approval Elements of PBN Concept- Navigation Specification -

  8. RNAV RNP Elements of PBN Concept- Navigation Specification - International NS in Volume II of PBN Manual NAVIGATION SPECIFICATION 3 2 • RNAV System PERFORMANCE Document used by State as basis for Certification & Operational Approval Better Performance On-Board performance Monitoring and Alerting

  9. RNAV RNP Elements of PBN Concept- Navigation Specification - 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

  13. Elements of PBN Concept- Navigation Application - NAVIGATION APPLICATION 1 3 • The APPLICATION (use of) the Navigation Specification and Navaid Infrastructure - • For example: Routes based on RNAV and RNP Specifications (these rely on theNavaid Infrastructure); • For example: SIDs/STARs based on RNAV and RNP Specifications; • For example: Approach procedures based on RNP Specifications

  21. Concept Summary (3) NAVIGATION SPECIFICATION RNAV RNP

  22. Concept Summary (3) NAVIGATION APPLICATION RNAV RNP

  23. Previous RNP Concept Why Change to PBN? • PERFORMANCE • Functionalities • Navigation Sensors • Air crew requirements • 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

  24. 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
