    PBN - Commitment from States37th ICAO General Assembly

    Resolution A37-11 supersedes A36-23

    A37-11 urges all States to complete a national PBN

    implementation plan as soon as possible to achieve: PBN for en route and terminal areas

    According to established timelines and intermediate milestones;

    PBN approach procedures with vertical guidance (APV) for all instrument runway ends (as primary or back-up for precision approach) by 2016 , 70% by 2014

  • Commitment from States37th ICAO General Assembly

    Main additions to A37-11 compared to A36-23:

    Requirement to add LNAV minima to any approach chart for approach procedures with vertical guidance

    Allow States to publish LNAV only approach if there is no traffic equipped for operations with vertical guidance.

    A37-12:ICAO global air navigation plan

    Calls upon States, planning and implementation regional groups (PIRGs) and the aviation industry to utilize the guidance provided in the GANP for planning and implementation activities;

    Instructs the Council to ensure that the GANP is continuously maintained up to date in light of further operational and technical developments, in close collaboration with States and other stakeholders; and

    Instructs the Council to organize a Twelfth Air Navigation Conference in 2012, to develop longer-term planning for ICAO based on an update of the GANP.

  • But still not worldwide implemented!

  • Roadblocks

    Lack of expertise Airspace development

    Operational approval process

    Pilots and ATC Controllers training

    Coordination between Stakeholders National

    Regional

    And some Misconceptions

  • Misconceptions on PBN

    PBN, it looks complicated but it is not:

    It does not add new navigation philosophy, but just isa pragmatic tool to implement navigation procedures for aircraft capability that exists for more than 30 years!

    It does not require States to completely overhaul navigation infrastructure, but can be implemented step-by-step

    It does not require States to implement the most advanced navspec, only needs to accommodate the operational needs

    Slide 21

  • Slide 22

    Need to transition from planning to implementation

    Focus from new Standards to implementation

    guidance and State assistance

    Implementation guidance

    Education

    Direct assistance

  • New implementation guidance

    CDO manual (Doc 9931)

    CCO manual (maybe combined with CDO manual) to be expected in draft by end this year/early next year

    Airspace design manual (based on Eurocontrolhandbook/ICAO course material) to be finalized by end this year

    Ops approval manual (based on COSCAP handbook and to include sample regulatory approval guidance), finalized as early draft, to be finished end of this year

    GNSS manual. Revision to bring in line with PBN

    Slide 23

  • Education

    Airspace design

    Ops approval

    Slide 24

  • Direct assistance Go- teams

    Go-Team visits in coordination with IATA 4 per year Target: reasonably advanced PBN States who:

    Have political will Potential capability Willingness to help other States in Region

    Output: Go-Team Report

    Areas of improvement and recommendations Enhancement of national PBN Implementation Plan On case by case basis: sample implementation project

    (CDO/approach)

    Slide 25

  • Beyond implementationNew requirements .

    New navigation Specifications under consideration

    a) RNP 2 (Remote and oceanic)

    b) Advanced RNP

    c) RNP 0.3New Navspecs still under scrutiny to ensure full operational justification

    Accommodation of simple GNSS aircraft to be PBN approved by either:

    a) New Navspec (RNP2 light under consideration) or

    b) Facilitation through easy approval mechanism
