What is the intent of the PBNImplementation Plan

The PBN Implementation Plan should bedeveloped by the State together with the

stakeholders concerned and is intended toassist the main stakeholders of the aviationcommunity plan a gradual transition to the

RNAV and RNP concepts.

4/24


The main stakeholders of the aviation community thatbenefit from this roadmap and should therefore be

included in the development process are: Airspace operators and users

Air navigation service providers

Regulating agencies National and international organizations

5/24


The PBN Implementation Plan is intended to assistthe main stakeholders of the aviation communityplan the future transition and their investment

strategies. For example, airlines and operators canuse this roadmap to plan future equipage andadditional navigation capability investments;

air navigation service providers can plan a gradual

transition for the evolving ground infrastructure. Regulating agencies will be able to anticipate and

plan for the criteria that will be needed in the future

as well as the future regulatory workload andassociated training requirements for their work force.5

What are the objectives ofthe PBN Implementation Plan

Provide a high-level strategy for the evolution ofthe navigation applications to be implemented inthe State in the short term (2010-2012) and

medium term (2013-2017). This strategy is basedon the concepts of PBN, Area Navigation (RNAV)and Required Navigation Performance (RNP),which will be applied to aircraft operations

involving instrument approaches, standarddeparture (SID) routes, standard arrival (STAR)routes, and ATS routes in oceanic and continentalareas in accordance with the implementation

goals in the Assembly resolution;6


7/24

What principles should be applied indevelopment of the PBN Impl. Plan

The implementation of PBN in the State should be based onthe following principles:

Continued application of conventional air navigationprocedures during the transition period, to guaranteeavailability by users that are not RNAV- and/or RNP-equipped;

Development of airspace concepts, applying airspacemodelling tools as well as real-time and acceleratedsimulations, which identify the navigation applications that arecompatible with the aforementioned concept;

Conduct of cost-benefit analyses to justify the implementationof the RNAV and/or RNP concepts in each particular airspace;

Conduct of pre- and post-implementation safety assessmentsto ensure the application and maintenance of the establishedtarget levels of safety.

Must not conflict with the regional PBN implementation plan.7

A36-23: Performance basednavigation global goals

Primary objective of ICAO is ensuring the safeand efficient performance of the global AirNavigation System;

Improvement of the performance of the AirNavigation System on a harmonized, worldwidebasis requires the active collaboration of all

stakeholders;8


9/24


The Eleventh Air Navigation Conference recommended that ICAO:

as a matter of urgency, address and progress the issues associatedwith the introduction of area navigation (RNAV) and required

navigation performance (RNP);

develop RNAV procedures supported by global GNSS for fixed wingaircraft, providing high track and velocity-keeping accuracy tomaintain separation through curves and enable flexible approachline-ups;

develop RNAV procedures supported by GNSS for both fixed androtary wing aircraft, enabling lower operating minima in obstacle rich

or otherwise constrained environments;9


10/24


Resolution A33-16 requested the Council to develop a programme toencourage States to implement approach procedures with verticalguidance (APV) utilizing such inputs as GNSS or distance measuringequipment (DME)/DME, in accordance with ICAO provisions;

Recognizingthat implementation of approach with vertical guidance(APV) is still not widespread;

Recognizingthat the Global Aviation Safety Plan has identifiedGlobal Safety Initiatives (GSIs) to concentrate on developing a safetystrategy for the future that includes the effective use of technology toenhance safety, consistent adoption of industry best practices,alignment of global industry safety strategies and consistent

regulatory oversight;10

The Assembly:

1. Urgesall States to implement RNAV and RNPair traffic services (ATS) routes and approachprocedures in accordance with the ICAO PBN

concept laid down in the Performance BasedNavigation Manual(Doc 9613);

12

2. Resolvesthat:

a) States and planning and implementationregional groups (PIRGs) complete a PBN

implementation plan by 2009 to achieve:

b) ICAO develop a coordinated action plan to

assist States in the implementation of PBN andto ensure development and/or maintenance ofglobally harmonized SARPs, Procedures for AirNavigation Services (PANS) and guidancematerial including a global harmonized safetyassessment methodology to keep pace withoperational demands;

15


16/24


3. Urgesthat States include in their PBNimplementation plan provisions for

implementation of approach procedures withvertical guidance (APV) to all runway endsserving aircraft with a maximum certificated take-off mass of 5700 kg or more, according toestablished timelines and intermediatemilestones.
