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.

Commitment by positive business case: minimum investment by using existing airborne technology

RNP Approach allows 3D use

Safety - accessibility

16Project title (Insert, Header & Footer)

• 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)

Capacity - efficiency

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

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.

29

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)

– Recommendations and guidance on data exchange, no obligations.

– Standards for eAIP, AIXM, Training, Quality Guidance Material

http://www.icao.int/anb/aim

30

Transition to AIM

• 2013, Information Management

– Amendment 37 Annex 15 & Amendment 57 Annex 4 become applicable.
