Elements of PBN Concept- Navaid Infrastructure -
  • Ground-based Navigation Aids (Navaids)
  • VOR DME (Not NDB)
  • Space-based Navaids

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?

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

NAVIGATION APPLICATION

  • The APPLICATION (use of) the Navigation
    Specification and Navaid Infrastructure -
  • For example Routes based on RNAV and RNP
    Specifications (these rely on the Navaid
    Infrastructure)
  • For example SIDs/STARs based on RNAV and RNP
    Specifications
  • For example Approach procedures based on RNP
    Specifications

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
