• ARINC
• SITA
• FABEC
• VDL2 Focus Group in the afternoon
• VLD2 multi-frequency
• VDL2 white papers
• Guidance to implementers documents
• Provider Abort issue

5
EUROCONTROL Specification on DLS

• Document Approved on 02 March 2009
• Replaces the LINK Baseline document v 1.4
• To be referenced by the AMC20-11 for
  airworthiness

6
Community Specification on DLS

• EC Mandate to ESO for the development of
  Community Spec for Datalink Services Jan 09
• Only ETSI reacted on the mandate
• Mandate states in line with EUROCONTROL Spec,
  ICAO, EUROCAE etc.
• EUROCONTROL will participate to the ETSI TG-25
  meetings
• Document approval by the group planned mid
  March 2010

7
VDL Mode 2 Activities

• White Papers
• ATN A/G Router Proliferation
• Discourage proliferation of A/G Routers with
  limited geographical connectivity to be
  included in the NPD
• ATN Routing Ambiguity following VDL Handoff
• Conclusions to be documented in the Guidance to
  Airborne implementers document
• Default VDL Service Provider (ACSP) for non-AOC
  Operators
• Discussion on-going institutional solution
  agreed in principle
• VDL2 Monitoring (MOON)
• Detect non-compliance to standards as soon as
  possible
• Interoperability efficiency, protecting
  performance spectrum
• Monitor traffic growth and timely prepare
  channels deployment
• Extensively used during the PAs investigations

8
VDL Mode 2 Multi-frequency

• EUROCONTROL VDL simulations predict at least
  three channels required to satisfy eventual
  LINK2000 load
• Rapid growth of VDL M2 traffic expected following
  introduction of forward-fit mandate in 2011
• Step-wise deployment of 4 VDL M2 protected
  channels foreseen (including the CSC)
• Need to maintain efficient use of spectrum and
  scalability throughout deployment process

It has to work as soon as it is needed!
9
VDL M2 Multi-frequency Deployment

• FMG SG/15 in Dec 08 was of opinion that full
  sharing of the frequency channels between all
  providers would be the most efficient one.
• Co-ordination between providers to regulate use
  of channel
• Avoid congestion
• Maintain stability
• Take account of transition
• LINK2000 will prepare a Discussion Paper to
  commence dialogue with providers on co-ordination

10
VDL M2 Multi-frequency Validation (1)

• Three phases validation strategy agreed
• Phase 1 Laboratory testing
• Phase 2 Flight trials in a limited VDL2
  multi-freq ground implementation
• Phase 3 Airline flights in limited VDL2
  multi-freq ground implementation
• ARINC 750 Troublemaker to emulate failures on RF
  link
• Permits testing of error cases in Phases 1 and 2
• SITA contracted to support validation via
  Maastricht UAC Contract
• PM-CPDLC Pioneer avionics will support VDL
  Multi-Freq

ATN Provider AbortsBackground

• Escalating observation of PAs at UAC Maastricht
  during 2007-08
• 1 in 20 CPDLC flights affected at start 2007
• Worse than 1 in 10 by early 2008
• Trend suggests progressive deterioration as
  equipped traffic grows
• Significant risk to successful LINK2000
  Operations
• Aggressive investigations initiated to understand
  origin and identify solutions
• Provider Aborts arise from a number of different
  causes
• Application related
• VDL/ATN Comm related

13
ATN Provider AbortsStatus

• Maastricht ES upgraded Nov 08 (35 overall
  reduction in PAs)
• PAs during CPDLC Establishment reduced to
  negligible levels BUT
• TP4 interoperability issue exposed with MkII CMU
• Short term workaround expected April 09
• Elevated CNO PAs appear due to single rogue VDR
• Airbus test flight of FIN avionic configuration
  Sep 08
• issues identified and corrected in FANS B
• issues identified with VHF920 VDR correction
  under way
• FIN will upgrade (Mar/Apr 2009) three airframes
  with VHF2100 VDRs
• Performance will be monitored via LISAT and MOON
• LINK2000 Flight Trials in Dec 08
• No PAs observed
• Several instances of high Channel Utilisation
• Analysis continuing
• Recent increase of BER PAs no VHF920 VDR
  involvement

14
ATN Provider AbortsWay Ahead

• Continue dialogue with Airbus and RC
• FIN and more recently BER
• Monitor FIN PAs, following introduction of
  VHF2100
• Finalise analysis of high Channel Utilisation
  observed on LINK 2000 Flight Trials

15
L2K Guidance Material Development (1)

• Guidance to Implementers of L2K
• Ground Implementers Airborne Implementers
• Two main parts in each document
• Introduction, system description and to do list
• pointer to existing documents (No overlap)
• NPD, NAP, Gen ACSP, etc
• Lessons Learned/White papers (more detailed
  contents)
• General tutorial information
• Included in the Ground document Annex and refered
  to from the Airborne one
• Submitted for LIT review comments
• Comments by end April 09

16
L2K Guidance Material Development (2)

• Network Planning Document
• High level guidance on the LINK 2000
  communication infrastructure
• To be amended with
• institutional solution (preference) to Non
  AOC airlines (by alternative ACSP)
• ATN A/G Router Proliferation
• Generic ACSP Requirements Document
• Proposed to L2K ANSPs as basis of ACSP SLA
  establishment
• Version 1.5 released for comments
• Multi-frequency support added
• used as basis for UAC Maastricht Call-for-Tender
  for VDL Service

Possible revisions at later stage of Link2000
wide deployment using more real-time statistics
operational feedback
17
Link Statistics reporting

• Based on regular (monthly) reports by ANSPs
• Today, performed by Maastricht UAC
• Future, ANSPs joining operations encouraged to
  participate
• Communication via public web space
  http//www.eurocontrol.int/link2000/public/standar
  d_page/stats.html
• LISAT LInk Statistics reporting and Analysis
  Tool

18
LISAT Overall perspective
19
LISAT status and plans

• Initial deployment early 2008
• Extensively used in PA statistics analysis
• Tool enhancements to date
• Significant Performance improvements
• Additional filtering capabilities e.g. ops
  error, technical error, LACK time, etc.
• Tool enhancements foreseen
• Integration with PRISME for a/c REG and Flight
  data
• Connection with MOON for VDL2 data

20
Next Events

• Pre-LIT16 on 13 October 09

Conclusion

• LIT Continues to Build Consensus
• It is still here to help Implementersin an
  efficient way
