5. Essential Requirements (ER)
Systems and constituents shall be compliant with the Essential requirements (ER)
Seven generic ERs
Seamless operation
Support for new concepts of operation
Safety
Civil-military coordination
Environmental constraints
Principal governing the logical architecture of systems
Principal governing the construction of systems
ICAO WG – N meeting, Brussels, 06 July 2006

6. Implementing Rules (i)
Implementing Rules (IR) for interoperability will be compulsory
IR shall determine any specific requirement that complements or refine the Essential Requirements, wherever relevant cross-references to ICAO SARPs, doc 4444, doc 7030
IR shall also describe the coordinated introduction of new, agreed and validated concepts of operation or technology
ICAO WG – N meeting, Brussels, 06 July 2006

7. Community Specifications
Community Specifications (CS) are means of compliance and will be the subject of specific requests to standardisation organisations issued by the Commission
CS may be European Standards drawn up by CEN/CENELEC/ETSI in cooperation with EUROCAE
CS may be Eurocontrol specifications for matters of operational coordination
ICAO WG – N meeting, Brussels, 06 July 2006

8. Development of Implementing Rules
Draft IR to be developed by Eurocontrol in conformity with the mandates issued by the Commission
IR shall specify the conditions of implementation (including dates)
IR shall be adopted by the Commission following the formal opinion of the Single Sky Committee (SSC) and published in the Official Journal

HMIs, pilot, controller.
Interoperability levels
Selection of data link services among existing standards
Selection of end to end communication mechanism among existing standards
Selection of air – ground communication link among existing standards
Selection of data link ATC procedures
Identification of subjects for prescriptions in the IR addressing interoperability levels of the target
ICAO WG – N meeting, Brussels, 06 July 2006

15. Interoperability analysis/2
Deployment conditions
Data link EU airspace
Categories of a/c to be equipped
Responsibility of stakeholders
Identification of subjects for prescriptions in the IR addressing the deployment of DLS in the EATMN & EU airspace
ICAO WG – N meeting, Brussels, 06 July 2006

16. Alternatives for the RA
On the basis of subjects identified in the interoperability analysis
3 Alternatives are proposed to delineate the level and details of prescriptions, and the balance between IR and MoCs
Impact on stakeholders varies significantly with the Alternative considered

19. ICAO WG – N meeting, Brussels, 06 July 2006
The Way Forward (1/2)
Based on comments received and to ensure interoperability of data link services, the intended approach is to undertake the parallel development of:
An IR containing high level mandatory requirements on data-link services, enabling technology and deployment in the EATMN
A EUROCONTROL specification containing the detailed mandatory requirements, to be referenced in the IR. Technical requirements would describe implementation based on ATN/VDL2 ICAO SARPs
Some issues require further consideration: FANS aircraft, airspace of applicability, target aircraft population, etc.
ICAO WG – N meeting, Brussels, 06 July 2006

20. ICAO WG – N meeting, Brussels, 06 July 2006
The Way Forward (2/2)
Structure of IR would allow for recognition in due time of other MOCs
Specifications developed when evidence exists that other technical solutions meet IR requirements
Way of recognising new MOCs has to take into account need for interoperability
Note: The proposed IR is not intended to limit implementation to only those data link services identified in the RA. However, at least these services shall be implemented. Additional data link services may become mandatory in the future.
