9. Background ATM a/g voice capacity is reaching saturation
Most 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 independently
None 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

10. FAA/Eurocontrol Joint Study

13. AP17: Current Status Concept and Requirements Technology Pre-screening
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

14. Air Ground Communication Focus Group

15. 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.

16. AGCFG/1 Organised in two parts
Presentations 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

17. 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

18. 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

19. 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

20. 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 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.
DRAFT

21. 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.

23. Next Steps

24. ECTL: AGCFG and NexSAT
The satellite investigations is part of the considerations for the future systems
Do we need both groups? - Two options
Merge the two groups
Keep them separately
(but arrange meetings, when required, sequentially to minimise travel expenses
