ICAO Forum on Integration and Harmonization of NextGen and SESAR into the Global ATM Framework 8-10 September 2008 Lex Hendriks Deputy Director DAS, EUROCONTROL ASAS-TN Final Workshop, Roma, 12 November 2008 ICAO hosted the Forum on Integration and Harmonization of NextGen and SESAR into the Global ATM Framework at the ICAO Headquarters from 8 to 10 September 2008. The event was attended by approximately 370 participants from 52 contracting States, 18 international organizations, air navigation services providers, industry and academia. The objective of the Symposium was twofold: a. Provide a venue to listen to the aviation community regarding its needs for standards and recommended practices for the new generation of aviation systems currently being developed; and b. Provide a venue to widen the circle of information regarding the progress of these two key aviation systems and open the floor to any developments underway in other States. European Organisation for the Safety of Air Navigation

The Event SESAR & NextGen presentations Other Perspectives Performance, concept, architecture Roadmap, transition programmes International cooperation Other Perspectives ASECNA, Australia, Brazil, China, India, Japan, Russian Federation Standard organisations Airspace users, ANSP, Airports associations Staff associations Only indirect comparisons ICAO framework acknowledged but seen as insufficient Air transport crisis in the background General reference to ICAO Global Concept and Global Plan Expectations on direct local benefits from cooperation with SESAR/NextGen, but with short-term focus A summary of the agenda (2 main parts) and main impressions All presentations on ICAO web site. Very infomative, especially the efforts and programmes from other regions; they have different, sometimes basic problems to solve. SESARand NextGen presentations were consecutive per toic, no joint presentation, no direct comparison made.

Around the Event EC, EUROCONTROL & SESAR JU formed a European common front in promoting the SESAR programme A number of bilateral meetings held on the sidelines of the Forum with relevant third countries to explore next steps for cooperation in the SESAR framework

SESAR-NextGen Comparison Overall: broad alignment Both operational concepts consistent with ICAO Global Concept Key common tenets Performance orientation Trajectory management/operations, gate-to-gate Advanced automation New separation modes SWIM “Devil is in the detail”: more discussions and validation needed Terminology Assumptions Roadmaps Just a few words in this presentation Some of the questions to be jointly clarified if we want to achieve actual interoperability: Language/definitions around trajectory based operations, for example: who can modify what, when? Decision control loops across the ATM roles (ATFM, planning ATC, tactical, AOC vs pilot, etc)? Same decision/control loops across the ATM roles? Similar goals, definitions & timeline of the applications? Can we identify & use common definitions for the same notions and different ones for different notions? For example “SWIM” is not used in the same way on both sides Assumptions on concepts need be explicit/shared Need detailed scenarios on trajectory based operations

SESAR & ICAO ATM Master Plan underlines the importance of ICAO action, leading to global interoperability, in particular Timely availability and effective application of SARPS & PANS material based on validated concepts/technologies, allowing regions with early needs to progress at the pace required by their traffic volumes/density Coordinated, synchronised implementation plans for synergies across regions and consistent requirements on airspace users European presentations influenced significantly the conclusions drawn by ICAO

SESAR & ICAO SESAR needs more ICAO material to ensure interoperability Common time reference New flight plan / flight object Information Management (data models, quality of service requirements, sharing rules, distribution process) 4D Trajectory exchange format Trajectory exchanges & “contracts” procedures D/L applications for trajectory data exchange New wake vortex separations based on time Procedures for delegation ATC/Pilots Time based separations Suggested area for particular attention UAS (sense & avoid: new rules & technologies)

Forum’s Conclusions by ICAO Secretariat ICAO only common global framework, facilitate harmonisation and interoperability through timely production of necessary SARPs ICAO will Need to move from standardizing “pieces” to “packages or groupings” of capabilities and procedures to deliver a specific level of operational capability and performance (with targets) Need to restructure itself to be responsive to demands Work with other international standards-making bodies Prioritize the supporting technical specifications to be addressed Work with SESAR JU and the US to review needs for standards Review structure & terms of reference of all ICAO Panels & Groups, and reset priorities Host periodic Future Aviation Systems Forums

Conclusion SESAR: a new dimension to European ATM & regional integration efforts SESAR is for all airspace users, global interoperability is a priority ICAO has an essential role for this SESAR / NextGen cooperation is not a beauty contest but a vehicle to converge Airspace users requirements should drive the process Cooperation SESAR/NextGen is essential and active Joint successes have already been achieved, more need be achieved We should be even more ambitious to find common solutions We need a responsive ICAO
