• Why do we need to start now for a system(s) to be
  operational in 2020?

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

• 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

AP17 Current Status

• 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

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
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
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
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
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.

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.

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
