Overview of the COCR (1/3) Captures the operational requirements for Phase 1 (from now to 2020) and Phase 2 (beyond 2020) Concept in Phase 1 is drawn largely from EUROCONTROL ATM concept document for 2008-11 & 2020 and beyond Concepts in Phase 2 are based on more extensive use of Phase 1 services and NGATS operations (e.g. 4D Trajectory Management) Autonomous operations take place in some parts of the airspace Auto-EXECUTE has been added in line with NGATS concepts for wake vortex separation Based on postulated ATS operational concept using existing documentation and extending it into the future Provides traceability to information sources 4/29/2019 F E D E R A L A V I A T I O N A D M I N I S T R A T I O N • A I R T R A F F I C O R G A N I Z A T I O N

Overview of the COCR (2/3) From the operational concepts, information flows have been identified in representative test volumes of airspace i.e. ‘positions/sectors’ in Airport, TMA, En Route, & Oceanic. Airport positions & Radar sectors in Phase 1 similar to today Radar sectors larger in Phase 2, perhaps 2-3x. Airport positions pretty much the same as Phase 1 Covers all ATS and AOC air-to-ground and air-to-air voice and data communication Includes ADS-B and AOC applications Includes micro-jets & UAV’s (only ATC control element) Does not include Air Marshall, UAV Command & Control, SWIM, or spacecraft communications 4/29/2019 F E D E R A L A V I A T I O N A D M I N I S T R A T I O N • A I R T R A F F I C O R G A N I Z A T I O N

Overview of the COCR (3/3) Identifies all communication requirements based on safety and security analysis Availability, continuity, reliability and latency Requirements are technology independent Communication requirements are then used in a queuing model for communication loading (b/s per service volume) Aircraft numbers are grown over time using EUROCONTROL SAAM data in ECAC – MLM in US At the end of the document a typical example use of the results volumes in a real world environment Will help technology assessment activity 4/29/2019 F E D E R A L A V I A T I O N A D M I N I S T R A T I O N • A I R T R A F F I C O R G A N I Z A T I O N

COCR V1.0 Summary Overall In terms of capacity, future ATS air/ground data requirements appear to be relatively modest. However, this problem has more than one dimension, as delivery of air traffic services requires simultaneous achievement of many, often challenging, requirements. The safety-driven combination of capacity, integrity, reliability, latency and coverage requirements typically dictate unique solutions for aviation. While Phase 2 requirements appear to be beyond the capabilities of systems currently deployed, numerous advanced technologies, as well as options for further evolution of today’s most capable systems, should meet all but the most demanding needs. To implement this two-phased vision affordably, careful examination of the services, especially those that drive requirements, will be necessary to balance costs and benefits. 4/29/2019 F E D E R A L A V I A T I O N A D M I N I S T R A T I O N • A I R T R A F F I C O R G A N I Z A T I O N

Current Status Version 1.0 is mature Significant feedback from industry (over 300 comments received) Comments incorporated into V1.0 COCR V1.0 distributed at the beginning of March 2006 On the EUROCONTROL website Provided to SESAR Signed by FAA senior management and on their website Input to NGATS Some outstanding issues to be resolved in a new version of the COCR 4/29/2019 F E D E R A L A V I A T I O N A D M I N I S T R A T I O N • A I R T R A F F I C O R G A N I Z A T I O N

COCR Version 2.0 Activities to finalise COCR Version 2.0 include: Ensuring satisfactory agreement among stakeholders with some of the more stringent services and the surrounding concept of their use Capture and definition of missing services Further definition of the services to ensure a more complete understanding of their operational use Categorisation of the services into groups based on likeness Assessment of the safety and security requirements associated with each group Assessment of the associated performance requirements impact Adding an Executive Summary Respond to comments received on COCR Version 1.0 and clarify areas of ambiguity 4/29/2019 F E D E R A L A V I A T I O N A D M I N I S T R A T I O N • A I R T R A F F I C O R G A N I Z A T I O N

Phase 2 Services Better description and operational definition of Phase 2 services e.g. COTRAC Clarification of their operational use Development of specimen OSED’s to better define safety requirements & provide more accurate communication performance assumption Recognising that data services are the ‘primary’ means of communication Clarify the use of service requirements in or at the boundary of Autonomous Operations Areas Understand the ramification of the operational scenarios on the technical performance Are they realistically achievable? 4/29/2019 F E D E R A L A V I A T I O N A D M I N I S T R A T I O N • A I R T R A F F I C O R G A N I Z A T I O N

Conclusions COCR Version 1.0 was a major achievement Being widely reviewed Input to SESAR and NGATS Used in technology assessment Further refinement of the COCR Concepts being reviewed in the light of safety & performance requirements Review feasibility of meeting the concept requirements Close co-operation between FAA and EUROCONTROL to complete tasks Progress will be reported to ACP and feedback sought COCR Version 2.0 targeted for completion in March 2007 4/29/2019 F E D E R A L A V I A T I O N A D M I N I S T R A T I O N • A I R T R A F F I C O R G A N I Z A T I O N
