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

Developing a VDLm2 coverage – Foster a regional approach

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

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

Federating the Service

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.

WAC 2015 | © SITA 2015

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

23 WAC 2015 | © SITA 2015

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

WAC 2015 | © SITA 2015

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

WAC 2015 | © SITA 2015

SITA VHF Partnership• Currently with individual ANSPs
