ARINC PETAL IIe VDL Mode 2, ATN …and beyond GLOBAL ink ARINC PETAL IIe VDL Mode 2, ATN …and beyond Prepared for: ATN2001 18 September 01 Sarah MacLellan (slm@arinc.com)
ARINC’s Goals for PETAL IIe Demonstrate viability/suitability of CPDLC over VDLM2/ATN Work out many technical and ops issues for CPDLC over VDLM2/ATN in a trials environment Forcing function to keep forward momentum for CPDLC First step toward full operations: US-based CPDLC program, and Link 2000+
ARINC’s PETAL Role Test partner with Rockwell Collins on VDL M2 US mini-network to support AAL certification European network, coverage for Maastricht UAC airspace
ARINC-Rockwell Collins VDL M2 Testing Testing 3/00 through 4/01 AVLC Also took advantage of concurrent AOA work v8208 Integration of ATN End-to-end RC-ARINC-EUROCONTROL Experimental Centre (EEC) testing 2-4/01 ARINC Ground Test Station (AGTS) in Cedar Rapids Production hardware Production software Test/instrumentation code
US Certification Mini-Network AGTSs at TUL and DFW Routers and network management in Annapolis Connection to EEC and Maastricht (via EEC) Installed early Apr 01 Test flights late Apr - end of May Certification flight 29 May

Technical Lessons Reaffirmed Complex interaction among air and ground components Lab testing only takes it so far Flight operations necessary to identify operational issues
VDL M2 Technical Items AEEC Timer values at v8208 and TP4 layers Timer implementation inconsistency in specifications Signal Quality Parameter (SQP) calculations/ air-initiated handoff scenarios RF Signal in Space strength variable due to combination of antenna location, aircraft attitude, ground antenna pattern, and structural or geographic influences PETAL team completing identification, investigation, and recommendation on all anomalous behavior seen during the trials
Programmatic Lessons Reaffirmed Strong central lead is imperative Committee and congeniality takes you only so far - every once in a while you need a boss Integration Team concept works Stakeholders committed to success Frequent interchange of status
PETAL IIe a Success Demonstrated viability/suitability of CPDLC over VDLM2/ATN Worked out many technical and ops issues for CPDLC over VDLM2/ATN in a trials environment Forcing function/kept forward momentum for CPDLC First step for full operations: US-based CPDLC program, and Link 2000+
So where does ARINC VDLM2/ATN go from here?
VDL in Europe PETAL network status in review Customer base, location AOA coverage starts late 2001 for Airbus 3 VGSs (Toulouse, Lyon, Nice) 2002 and beyond: expand coverage AOC equipage expected to precede ATM Specific station/coverage schedules planned with customers AOC coverage expansion ~ ACARS, as customers equip Work with airlines, ATS Providers to plan support required for Link 2000+
Long Term Planned VDL Coverage ~ ACARS
CPDLC Build 1 9 Station network with redundant routers, connections to FAA PETAL+ functionality (network management, PETAL II identified modifications) Network install 4Q01 Operational testing with FAA and AAL through to 6/02 6/02 Initial Daily Use (IDU) CPDLC Build 1A will drive network expansion beginning 12/03
CPDLC Build I Coverage Map
US VDL Deployment Four additional AGRMs deployed Annapolis (2); Chicago (2); Livermore (1); New York City (1) Ground stations/VDL kits installation @ 3/week sites selected, surveyed, and installs scheduled Planning for 50 sites deployed by year end 2001, remainder in 2002
VDL Coverage Phases - CY 2002 Plan 175 Sites Phase 4 estimate Phase 3 fill in) Phase 2 fill in
EUROCONTROL and American Airlines Thank You EUROCONTROL and American Airlines for PETAL IIe/ATN! PETAL IIe single-handedly has influenced the course of data link implementation in Europe and US Demonstration Validation Risk Reduction First Step (breaking the chicken/egg challenge)
