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.
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.
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.
