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.

• Approximately 94% of daily departures are RNAV-capable
• More departure lanes and exit points to the en route airspace
• Capacity gain of 9-12 departures per hour
• Repeatable and predictable paths
• Benefits
• Increased throughput
• Reduced departure delays
• USD $30M annual benefit (at 2007 demand levels)
Improving runway utilisation at the world’s busiest airport – Atlanta (ATL)

CDO’s provide large benefits in fuel, emissions, and flight time reductions
May 2008 Demos:
• North Arrival STAR at Atlanta (ATL)
• 144 Liters of fuel savings and 360kg reduction in CO2 emissions per flight
• North Arrival STAR at Miami (MIA)
• 182-197 liters of fuel savings and 460-500kg reduction in CO2 emissions per flight
600 CDO night demos at ATL from August –November 2008
• Two North Arrival STARs
• 151-227 liters of fuel savings and 380kg reduction in CO2 emissions per flight

…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

AIM - Elements
• Phase 1 : Consolidation, mainly quality requirements; AIRAC adherence; WGS-84; and the provision of terrain and obstacle data.
• Phase 2 : Going digital, introduction of database-driven processes (eAIP, AIXM); enhance the quality and availability of existing products.
• Phase 3 : Information Management, new products and services; provision of the new data that will be required by the future ATM components.

Transition to AIM• 2009 - Completed. AIS-AIMSG first meeting 2-4 Dec. 2008, see
http://www.icao.int/anb/aim, -– Amendment 36 Annex 15 effective form July 2010.
Amendment 56 Annex 4; ( e-AIP, AIXM Recommendations, public internet, QMS)

• 2011, Going digital– Start developing Amendment 37 Annex 15 ( update to
AIXM, eAIP, eTOD& Amendment 57 Annex 4 (electronic charting, instrument procedure charts);
– Recommendations and guidance on data exchange, no obligations.
– Standards for eAIP, AIXM, Training, Quality Guidance Material
30
Transition to AIM
• 2013, Information Management
– Amendment 37 Annex 15 & Amendment 57 Annex 4 become applicable.
– Possible Divisional Meeting in 2014 to agree on new requirements for data exchange.
• 2016, Transition achieved
