Performance Based Navigation (PBN)
What is PBN?
PBN defines performance requirements for aircraft navigating on an ATS route, on a terminal or on an approach procedure. Those routes
and procedures are composed of way-points which are expressed by WGS 84 coordinates rather than fixes expressed by radial/bearing
and distance from ground navigation aids and permit the flexibility of point-to-point operations.
Benefits of PBN
Through the application of Area Navigation (RNAV) and Required Navigation Performance (RNP) specifications, altogether components of
PBN, PBN can provide the means for flexible routes and terminal procedures, reduce aviation congestion, conserve fuel, protect the
environment, reduce the impact of aircraft noise, improve safety and accessibility to challenging airports, and increase airspace capacity.
PBN Activities of APAC RSO
APAC RSO has supported States on various PBN implementation activities. Among them, key activities are RNAV and RNP Instrument
Flight Procedure design consultation and reviews, ATC Training customized to newly developed RNAV and RNP procedures by States,
airspace and ATS route review for PBN introduction, and PBN Airspace Design Workshop.
Also, APAC RSO actively participated in APAC PBN Symposium, APAC PBN Implementation and Coordination Group (PBNICG), PBN
Operational Approval Workshop and seminars related to PBN implementation.
What can APAC RSO offer to States?
APAC RSO can provide, not limited to, following PBN implementation supports for States:
◇ PBN Airspace Design Workshop (in house and on request)
▶ Contents: Area Navigation, Airspace Concept, PBN Concept and PBN Navigation Specifications, PBN Procedure Design
Considerations, Good Design Practices, Airspace Volume, CDO and CCO, Case Study on airspace design, etc.
▶ Duration: 1 week
◇ PBN Airspace review (on request by a State or sub regional bases)
▶ Contents: airspace review, ATS route establishment and realignment support, etc.
◇ PBN procedure design consultation (on request)
▶ Contents: airspace review, Ground Validation support, AIP publication review, etc.
◇ PBN ATC Training (on request)
▶ Contents: Introduction to PBN, Terminal Operations under PBN Environment, ATC Considerations in PBN, new PBN procedure review
and application, etc.
▶ Duration: 1 to 2 days
The APAC Flight Procedure Programme ( located in the same premises as RSO in Beijing) is proposing Procedure Design courses to all
APAC States. More information is available at :
