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

8 ICAO WG – N meeting, Brussels, 06 July 2006

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

Interoperability analysis/1

Interoperability target: functional architecture for DLS + Users Communication systems Data processing systems 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

Identification of subjects for prescriptions in the IR addressing the deployment of DLS in the EATMN & EU airspace

16 ICAO WG – N meeting, Brussels, 06 July 2006

Alternatives for the RA

On the basis of subjects identified in the interoperability analysis3 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

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.

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.
