EUR/NAT Data Link Steering GroupDLSG

ICAO DLSG created Under ICAO EUR/NAT Office Wide representation (UK, FR, PT, US, IS, Airbus, Boeing,…) Tasked to develop a harmonised data link service

First meeting March 2005 Workshop Action Plan:

Consistent with 3 steps strategy Second meeting October 2005

Creation of the ATN accommodation Drafting Group

Work on future systems (Step 3)

ATN accommodation Drafting GroupADG

Purpose: to study the accommodation of ATN aircraft (i.e. ED110A compliant)

in the FANS-1/A environment

Tasks To agree a list of technical and operational issues which could prevent

accommodation of ATN aircraft in FANS-1/A airspace, and develop a set of potential resolutions to those issues.

To develop a specification for a trial in a FANS-1/A environment (e.g. NAT) in order to validate the potential resolutions identified in the previous task.

Develop a draft interoperability specification for the accommodation of ATN aircraft in FANS-1/A airspace for input into RTCA SC189/Eurocae WG53.

ADG Progress

First Meeting April 2006 IRRF Approach Accepted Main Outcome:

Identification of all known issues that could potentially prevent an ATS Provider from accommodating ATN equipped aircraft

Second meeting June 2006 Main outcome:

Formulation of potential resolutions to the issues identified Several issues identified to be reported to the DLSG

ADS-C Application Issue

Current ADS-C SARPs version Meets most requirements but has shortcomings Airlines do not support it Improvement proposals available

ADG Proposed Solution Improve ADS-C application if it is done by June 2007 Working Arrangements to be defined and accepted by DLSG

ACP Coordination key element

Proposed ACP coordination

Chairman of SG-N2 of the ACP WG-W joins the ADG.

ADG material fed back to ACP for approval.
