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: USbased 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

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

Expected PETAL-IIe VDLM2 Coverage
25k Feet MSL
Technical Lessons Reaffirmed
Complex interaction among air and
ground components
Lab testing only takes it so far
Flight operations necessary to identify
operational issues
ARINC proprietary

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
ARINC proprietary
13
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+

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
