COCR development
EUROCONTROL
• Joint EUROCONTROL/FAA activity through common team
• Based on potential operational scenarios available at the
time in medium and long term
– Phase 1 – to 2020
– Phase 2 – 2020+
– Paradigm shift between Phases when data communications
becomes the ‘normal’ means of communication
• Future radio system is aimed at supporting the Phase 2
requirements
– Primarily for data communication
• COCR carried out an analysis to support these
requirements in various phases of flight

AIR TRAFFIC ORGANIZATION
Overview of the COCR (1/3)
EUROCONTROL
• Captures the operational requirements for Phase 1 (from
now to 2020) and Phase 2 (beyond 2020)
– Concept in Phase 1 is drawn largely from available material at
the time i.e. the 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 more advanced operations (e.g. 4D Trajectory
Management)
• Autonomous operations take place in some parts of the airspace
• Based on postulated ATS operational concept using
existing documentation and extending it into the future
• Broadly in-line with SESAR and NextGen concepts of
operation

AIR TRAFFIC ORGANIZATION
Overview of the COCR (2/3)
EUROCONTROL
• 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

AIR TRAFFIC ORGANIZATION
Overview of the COCR (3/3)
EUROCONTROL
• 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

Final COCR Version 2.0
EUROCONTROL
• Final version of the COCR completed in March 07 –
– Presented at ACP/1
– Responded to comments received on COCR Version 1.0 and
clarify areas of ambiguity
– Ensured satisfactory agreement among stakeholders with
some of the more stringent services and the surrounding
concept of their use
– Captured and defined missing services
– Further defined services to ensure a more complete
understanding of their operational use
– Categorised services into similar safety/operation groups
– Assessed the safety and security requirements associated with
each group
– Assessed the associated performance requirements impact
– Used to support the technology assessment

Evaluation Scenarios
EUROCONTROL
• Provide a family of generic operational
environments based on an extrapolation of the
Phase 2 COCR requirements so each expresses
the same requirement in different ways
• Reinterpretation of COCR requirements
expressed in a variety of ways that can be better
used during the technology assessment work
• This set of scenarios were used in the technology
assessment so as to compare results and identify
the technologies in an equitable way

Airport surface
EUROCONTROL
• The airport Test Volumes have been defined as:
– TV1.1 Airport Zone: 10NM diameter Cylinder including
Runway and Tower operations but excludes surface.
– TV1.2 Airport Surface: 5NM diameter circle including
Clearance/Ramp and Ground components. 5 NM was
representative of a large European airport

AIR TRAFFIC ORGANIZATION
Core Europe
EUROCONTROL
• Concept of Core Regional Test Volumes was introduced:
– TV4.1-4.4 have been redefined as Core Regional TVs
– They are representative of a global Large Area Volume (LAV)
such as ECAC or NAS.
– Designed to formulate a generic large area rather than a
specific case
– Characterise a large terrestrial coverage area, or large
terrestrial area inclusive of surrounding oceanic airspace
regions
• Core Regional Test Volumes provide a scenario for either
TMA or ENR airspace.
• Core Regional Test Volume designed for assessment of
space based technologies.

equitable way
• The choice of the appropriate scenario was
dependent on the technology
