2. 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+

3. 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

4. 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

5. 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

11. Expected PETAL-IIe VDLM2 Coverage
25k Feet MSL

12. Technical Lessons Reaffirmed
Complex interaction among air and ground components
Lab testing only takes it so far
Flight operations necessary to identify operational issues

13. 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

14. 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

15. 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+

16. So where does ARINC VDLM2/ATN go from here?

17. 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+

18. Long Term Planned VDL Coverage ~ ACARS

19. 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

20. CPDLC Build I Coverage Map

21. US VDL Deployment Four additional AGRMs deployed
Annapolis (2); Chicago (2); Livermore (1); New York City (1)
Ground stations/VDL kits 3/week
sites selected, surveyed, and installs scheduled
Planning for 50 sites deployed by year end 2001, remainder in 2002

22. VDL Coverage Phases - CY 2002 Plan
175 Sites
Phase 4 estimate
Phase 3 fill in)
Phase 2 fill in

23. 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)
