Background

ATM a/g voice capacity is reaching saturationMost severe in Europe and parts of the United States

8.33 kHz channel spacing in Europe 25 kHz channel spacing in the US

New ATM concepts are being introduced requiring enhanced data link performance (Cf CASCADE and Link2000+ Programs)

Various proposals have been made and progressed independentlyNone has achieved global endorsement

ICAO ANConf/11 Recommendation 7/4 (2003) requested investigations for a new, global A/G Communications System

FAA/EUROCONTROL/IATA agreed to collaborate to ensure that a new system was identified

FAA/Eurocontrol Joint Study

FAA/Eurocontrol 3 year joint study* Objectives:

Identification of requirements and operating concepts Investigation into new mobile communication technologies Investigation of a flexible avionics architecture

Development of a Future Communications Roadmap

Creation of industry buy-in

Improvements to maximise utilisation of current spectrum

Concept and Requirements Initial Draft completed (ICOCR) Next steps: Final version (FCOCR) to be ready by end 2005

Technology Pre-screening Develop methodology and criteria – Application with an

initial set of assumption (one system for both voice and data, for 2015)

Next Steps: Review of methodology and criteria and reconsideration of assumptions

AirGroundCommunicationFocusGroup

AGCFG

Objectives to provide a forum for discussions for all stakeholders

of the future aeronautical communications including terrestrial and satellite components for air/ground and air/air communications.

To identify commonalities in the stakeholders visions and objectives and eventually help to achieve convergence and build consensus in visions/strategies.

AGCFG/1

Organised in two partsPresentations to provide information and share views

AP17, VHF band – current status Airbus, DSNA and LFV views AeroBGAN, Anastasia, BVHF

Discussions on options vision(s) and strategy(-ies) Some emerging conclusions/consensus Starting point: to agree on key points and

terminology/definitions

DRAFT

AGCFG/1: Key Points (1/3)

DSB-AM voice will continue to be used Likely to have different technologies supporting voice

and data Likely to have multiple datalinks to meet QoS

requirements No new system(s) will be implemented before 2020 at

the earliest. Focus (mainly) on the avionics architecture and the

links (being the limiting factors)

DRAFT

AGCFG/1: Key Points (2/3)

Future Aeronautical Communications to include voice and data; a/g and a/a, p2p and

broadcast/multicast cockpit (ATC and AOC); other ATM exchanges (SUR, NAV, SAF/SEC info etc); if required (business case), cabin (AAC and APC),

with priority and pre-emption facilities for the safety/regularity ATS services.

DRAFT

AGCFG/1: Key Points (3/3)

Future Aeronautical Communications should: support all phases of flight; employ technology transparently to the user; enable smooth transition and provide support for legacy systems

(backward compatible); be implementable (time and space) in a phased manner and be

globally (if required) applicable; include provision(s) for growth in capabilities; maximise synergies (telecomms, military) and maximise reuse of

available technology; be spectrum and cost/benefit efficient and use efficiently existing and

already planned infrastructure; if required, use different technologies for different phases of flight

and/or applications;

DRAFT

AGCFG/1: Definitions

Future Communication Infrastructure, (FCI): The totality of the communications equipment required to support the end to end communications requirements of ATM in the 2020+ timeframe. The FCI includes the avionics systems, a/g data and voice links and the essential elements of the ground infrastructure.

Future: The term “future” in this context is used to denote the time period post 2020.

FCS: The acronym FCS will be reserved to refer to the Future Communications Study within the framework of AP17 of the EUROCONTROL/FAA MoC.

Future Communication Infrastructure

FCI is an amalgam of several systems, including the legacy systems that will still be operational in the future and new components (terrestrial and likely satellite), operating in a transparent way to the user.

Merge the two groups Keep them separately(but arrange meetings, when

required, sequentially to minimise travel expenses

The satellite investigations is part of the considerations for the future systems Do we need both groups? - Two options
