Developing a VDLm2 coverage
• One radio for all data− An aircraft captures only
one VGS at a timeAOC + ATC
• Radios on the same site must be in lineof
CSP1 CSP2
site must be in lineof sight− Even from different
providers
• Cover all gates at the airport
8 WAC 2015 | © SITA 2015
Developing a VDLm2 coverage
• The density of VHF stations seems to matter− Avionics may react in unpredicted ways− The more stations, the more signaling information is exchanged
on the frequency

Provider Aborts
• Provider Aborts− Unintended disconnection of the Air/Ground CPDLC connection− Currently way above the 5%
The ATN/VDLm2 service evidences performance issues

Provider Aborts
1. Interworking Issues− Mainly between
airborne and ground equipment
Two main categories of causes
2. Frequency Congestion
− Use of unique VDLm2 CSC Channel
VDLm2ATN
136.975 MHz -VDL 2 CSC
13 WAC 2015 | © SITA 2015
Need for a Central Reporting Office (CRO) and a Project Manager
1. CRO− Tracks and documents PA events
• With the support of all stakeholders: ANSPs, Airlines, Avionics manufacturers, CSPs, etc.
− Investigates and diagnoses causes
2. Eurocontrol DLISG2. Eurocontrol DLISG− Acted as a CRO
• Already identified and corrected a number of PA causes
− Was the only available industry forum on the subject− Is no longer convening
3. Implementation Coordination− Urgently needed to federate efforts
• Fully funded and empowered – May be the Deployment Manager?

VDLm2 Multi-FrequencySITA is Operational with VDLm2 Multi-Frequency
2009-2010: Multi-Frequency validation exercises with Eurocontrol
2014: Multi-Frequency operational at CDG
Results:- CU on CSC improved- Excellent CU on groundchannel

CertificationThe certification Context for Air/Ground Communicat ionServices is and remains unclear
1. Certification is applicable to ANSPs− CSPs are not ANSPs
2. Certification applies to Systems− Regulation 552/2004 defined DoC and DSUs associated with
systems
17 WAC 2015 | © SITA 2015
systems• An ATN router is provided with a DoC
− There is no DoC nor DSU defined for a service− NSA’s have diverging expectations regarding the contents of
DoC/DSU
3. A regional/pan-European infrastructure saves certification effort
Empowering ANSPsANSPs are the best placed to operate the Data Link Service
ANSPs are naturally armed for CNS operation
• The operation and maintenance of CNS is a key
DLS is part of CNS
• Data Link Services are a pre-requisite to SESAR
o CPDLC over ATN/VDLm2 identified
19 © SITAONAIR 2015
maintenance of CNS is a key ANSP skill
The SES Performance Scheme requires optimized CNS operation
• ANSPs have to address certification requirements
European rules passed on through NSAs
o CPDLC over ATN/VDLm2 identified as key milestone on the way to SESAR deployment
• SESAR concept is based on augmented use of Data Link
o 4D Trajectoryo SWIMo Etc.

Empowering ANSPsWhat would ANSPs bring?
Enhanced Monitoring
• Monitoring of VDLm2 frequencies
− Across national boundaries
Optimization
• Optimizing the VDLm2 Infrastructure
− Foster regional deployment of stations − Across airport sites
• Efficent CRO− ANSPs can establish and
operate a CRO close to operations
stations− Streamline the ATN routing
model− Reduce Air/Ground routers
• Leverage ANSP Association
20 WAC 2015 | © SITA 2015
Empowering ANSPsWhat do CSPs bring?
Bridge Gap to AOC
• CSPs maintain AOC contracts with airlines on a global basis
Expertise and Systems
• Providing fully proven VDLm2 stations
− Compatible with ACARS constraints, needed for VDLm2
global basis− Seamless service ignoring
airspace fragmentation
• CSPs provide revenue stream
− Cover the ANSP costs for supporting AOC traffic
constraints, needed for VDLm2 operation
• Providing ATN routing service− Act as ATN backbone
• Providing monitoring systems
− 30 years experience in operating data link VHF infrastructure
21 WAC 2015 | © SITA 2015
Empowering ANSPsThe SITA/ANSP VHF Partnership Model
Win / Win Approach
22 WAC 2015 | © SITA 2015
- SITA outsources the provision of itsA/G communication service (AOC, ATC)to the ANSP- SITA contributes to the ANSP costs for operating the A/G infrastructure
- The ANSP deploys a state-of-the art A/G datalink communication infrastructure at a fraction of the costs it would sustain if developed from scratch- The ANSP owns and operates the infrastructure anddevelops its know-how- The ANSP receives a cost contribution that is directly linked to the volume of AOC traffic
The Way Forward – Extended PartnershipEuropean Regional Initiatives
Eurocontrol Centralised Services• CS9.1
− Centralising communication infrastructure operation and
A6 Initiative
• Discussing with A6 ANSPs the federation of the Data Link Service
SJU ELSA Project
• VDLm2 performance and analysis study
− Launched by the SJU− In the wake of the
24
operation and management
• CS9.2− Centralising some
applications services
• In both cases, SITA is involved in the feasability study
Service
• SITA is willing to provide advising on various operation models
− In the wake of the European Comission workshop , and EASA report
− Will include VDLm2 multi-frequency
• SITA is part of the Consortium and is involved in all work packages

The Way Forward – Extended Partnership
EURO VDL Model
• ANSP governed CPDLC service delivery• Implements ANSP operational requirements• Armed to address system-wide validation
European Regional Initiatives• New governance model
empowering ANSPs
25
validation• Armed to address certification at the supra-national level• Cost effective through mutualisation of service operation, and AOC contributing to cost
