  • Performance Based Navigation(PBN)Canadian Implementation

    Presentation toAir Transport Association of Canada

    9 November 2010

  • Presentation OverviewPBN BackgroundPerformance Based NavigationWhy PBN?

    PBN in CanadaCurrent statusCoordinationFrameworkShort, Medium and Long term plans and timelines

  • *Performance-Based Navigation Moving towards Leveraging aircraft capabilities Safety, Capacity, Efficiency

    Optimize benefits: Airspace design CNS technologies Traffic Flow Management

  • Why PBN? - BenefitsFacilitates more efficient design of airspace and proceduresImproves safety, access, capacity, predictability, and operational efficiency.Minimizes reliance on ground based navigation routing and infrastructureReduces aviation impact on the environmentLess fuel burn and GHG emissionsLess noise pollution

  • PBN in Canada*

  • PBN in CanadaMay 2010 PBN Framework document developed. Linked to a Concept of OperationsSept 2010 NAV CANADA received implementation feedback from the ATOCC PBN Coordination GroupOctober 2010 Transport Canada committed to the creation of a CARAC Working Group to review the intent of PBN changes and the requirement for regulatory structureOctober 2010 NAV CANADA short term implementation strategies provided to the aviation community through the ATOCC / ANSNAC meetings

  • ATOCC PBN Coordination Group A combined NAV CANADA and customer group plus ADHOC industry experts coordinating activities and milestones Scope of related issues is expandingNAV CANADA PBN Coordination Manager : Jeff CochraneGoal is efficient and effective extraction of benefits from latest technology and coordinated implementation of PBNCooperative/collaborative approachCoordinated investmentExamination of ATC and Aircrew proceduresCoordination of testing and implementation of new or revised proceduresNow and future targets

  • CustomerCertification and qualificationLinking the Objectives*RegulatoryenablersANSPInfrastructure

  • PBN Framework - PurposeTo align NAV CANADA and our customer expectations, priorities and objectives for the implementation of PBN concepts in Canada over the next 10 - 15 years

    To implement where feasibleCoordinated with customer equipage plans*

  • Implementation StrategyShort Term (2010-15)Continue with the Windsor/Toronto/Montreal Airspace ReviewImplement RNP 10 in Edmonton FIRConvert remaining CMNPS and RNPC airspace to PBNDevelop prioritized list of airports for PBN and commence terminal redesigns based on PBN conceptsAddress AIS targets of opportunityCyclic reviewsContinue to implement 3rd party RNP designsDevelop internal capability for RNP designDecommission non-essential ground based nav aidsEducating NAV CANADA and the aviation community on PBNExplore viability of a Canadian or US test site for GBAS evaluation

  • Implementation StrategyMedium Term (2015-20)Continue Terminal airspace reviews in accordance with a prioritized list

    Re-assess and re-define the low level airspace structure in concert with the surveillance strategy, to incorporate PBN concepts

    Continue to expand the implementation of GNSS procedures as customer equipage expands

  • Implementation StrategyLong Term (2020 and beyond)Transition to a full PBN capability4D RNP operations and a gate to gate flight management environment

    Ground based navigation aid infrastructure is reduced to the lowest possibleBack up capability based on risk assessment/vulnerability studyRegulatory change is required12

  • What is PBN?Transition from ground based sensor navigation to area navigation (RNAV)Framework for defining navigation performance requirements/ specifications in terms of:Accuracy, Integrity, Availability, Continuity, Functionality A toolbox of navigation specifications that can be applied to a specific type of airspace to improve and standardize operationsIncludes both RNAV and RNP as types of specifications

    *

  • RNAV and RNPArea Navigation or RNAVEnables aircraft to navigate point to point by using onboard navigation equipment and updates from ground based ( DME) , aircraft based (inertial units) or space based ( GNSS satellite) navigation systems.

    Required Navigation Performance or RNPSame as RNAV except RNP aircraft have onboard performance monitoring and alerting capability*

  • *Performance Based NavigationReduced reliance on ground based navigation aids

  • Customer PerspectiveDeparture PhaseStandard Instrument Departures for every departure runway that quickly allows aircraft to join their route to destinationEn-route PhaseRoutes that are flexible based on that days operating conditions and upper winds. If flexible routes are not possible then a network of RNAV and RNP direct routes is preferredArrival PhaseStandard Arrivals that provide least track miles to the initial approach fix, preferably with a CDA profile from top of descentApproach PhaseA runway aligned with lateral and vertical guidance for every runway end that terrain allows*- Reference IATA

    *This presentation is a very brief primer on PBN. It is intended to orient you as to how we have arrived at where we are with PBN and a small look into the future of where we would like to take PBN.****PBN includes overlapping objectives in the three areas above.*Drilling down deeper we developed a PBN Framework document.*GBAS: Is a GNSS based ILS that is set up for a specific runway.***

    NAV CANADA has been moving from sensor based navigation to area navigation for several years. DME/DME and DME/DME/IRU systems along with our adoption of GPS in the mid 90s have supported our ability to develop RNAV based SIDs, STARs and approaches. As we move into PBN we now have a common lexicon that we can use when referring to these types of operations and well as how the equipment is certified and the operations authorized. The four standard terms that have been used when defining system performance now include a fifth functionality. This becomes more important as we try to reduce the obstacle clearance areas and provide more airspace capacity with PBN operations. Clarification of the two types of navigation specifications are on the next slide.**Very simply put, RNP = GNSS since this is currently the only system that can report to the flight crew with the required integrity the real time system performance. RNAV operations, supported by DME and inertial type systems, do not require the same onboard alerting, which means that their obstacle clearance areas will be larger and operations will be less demanding.**
