Airline Use of ACARS




SITA introduced the VHF ACARS services (VHF AIRCOM) in the
early 1980’s to support movement messages
Today, over 100 or the world’s airlines are VHF AIRCOM
customers with 4,000 aircraft and and additional 1,000 BizJets
The 5000+ aircraft which use the service collectively generate
500,000+ messages per day
In addition to basic movement information, AOC applications
have evolved to include:
–
–
–
–
–
–

Engine monitoring
Flight planning
Weight & Balance, Takeoff Data Calculation
Weather Information
Fuel information
Gate information
ACARS is considered to be a mission critical service
ATN 2003
Air Traffic Service use of ACARS
“Pre FANS”




Increasing numbers of ATS providers around the world have/are
planning initial ATS data link services:
– Departure Clearance (DCL)/Pre-Departure Clearance
Services (PDC)
– Oceanic Clearance Services (OCM)
– Digital-ATIS (D-ATIS) Services
In order to promote global interoperability, the AEEC and
Eurocae have developed standards for these services
– AEEC 623 (Message formats), Eurocae ED 85, ED 89 and
ED 106 (Performance Requirements)
SITA provides a D-ATIS Gateway service in order to allow non
623 compliant aircraft access to 623 compliant ground systems
and vice versa
SITA has launched a series of low cost Air Traffic Service
application systems to accelerate deployment
ATN 2003
Air Traffic use of ACARS –
“FANS1/A”



According to industry estimates, there are approx. 1,200 FANS
1/A equipped aircraft today……...and the number is growing !
To date, FANS 1/A services have been introduced in remote and
oceanic airspace, e.g. Pacific, Atlantic Oceans
Eurocontrol Maastricht UACC introduced operational FANS 1/A
(CPDLC) services via SITA AIRCOM in June 2003
– Maastricht airspace ranks amongst the densest airspace in the
world handling up to 4,000 flights/day


SITA currently provides direct FANS 1/A communications
services to 20 ATS providers including the FAA, Eurocontrol,
France, Egypt, Spain, South Africa, Singapore, Australia, Cape
Verde and India
SITA AIRCOM supports FANS internetworking with other DSPs
to ensure maximum availability of services to aircraft operators
ATN 2003
VDL Mode 2



One VDL Mode 2
channel provides at least
10 times more capacity
increase over one
ACARS channel
VDL Mode 2 is
operational today using
single 25 kHz channel
shared between service
providers
Selected by Eurocontrol
and the FAA as the initial
subnetwork technology
to enable CPDLC
– Consistent with IATA
position
ATN 2003
VDL Mode 2/AOA




AEEC defined in 1999 an interim architecture that serves as a
step towards ATN referred to as “AOA”, “ACARS over VDL
AVLC”
AOA allows existing ACARS applications to benefit from the
higher bandwidth offered by VDL M2
Main benefit, in addition to capacity increase, is that no change
required to the interface to airline or ATS ground systems
For aircraft, transition from AOA to ATN/VDL Mode 2 will require
a software upgrade to the avionics
– All ACARS avionics vendors now offer VDL AOA avionics
– Several major AIRCOM customers planning AOA retrofits across
the majority of their fleets

SITA evaluation of VDL AOA service with KLM (B737’s) has
demonstrated that the service is working

VDL Mode 2 Deployment Drivers

SITA deployment of VDL Mode 2 coverage is
being driven by two main factors:
– Airline customer requirements for increased ACARS
capacity in areas where the VHF analogue ACARS
frequencies most heavily used and congestion is
forecast
– Air traffic service providers requiring their Controller
Pilot Data Link Communications (CPDLC) to use ATN
over VDL
– Air traffic service providers have the choice to contract
service provision or deploy their own VDL networks
ATN 2003
SITA/AENA VDL Partnership

SITA signed an agreement with the Spanish Air Traffic
Service provider, AENA, that will result in:
– VDL 2 coverage over entire Spanish terrestrial airspace through
21 AENA owned SITA VGS’ by end 1Q 2004
– AENA responsibility for housing, maintenance and management
of the service
– Seamless AOC service for SITA VHF AIRCOM customers
– Platform for the introduction of CPDLC services over the ATN,
planned for 2006

Initial concrete example of the CNS industry/public joint
ventures foreseen by the European Commission’s Single
European Sky initiative
– Provides a pragmatic basis for European regional Air Traffic
Service provider entity owned VDL network service

SITA ATN Service



SITA plans to launch ATN Service in
support of the Link2000+ Pioneer Project
by mid 2004
Existing VDL AIRCOM provides coverage
over majority of Maastricht airspace
Deployment of ATN service requires
integration of ground/ground and
air/ground ATN Routers

Conclusions








Efficiency of airline operations increasingly dependant upon the SITA
AIRCOM Data Link Service
The use of the current VHF and Satellite AIRCOM service to support
ATS communications continues to increase – a true reflection of the
benefits provided
ACARS ATS applications will continue to play an increasing role
given the 10,000+ ACARS equipped aircraft in service today
Deployment of FANS 1/A services continues across the globe
VDL Mode 2 services are operational today
Major airlines are planning to upgrade to AOA to provide enhanced
performance to their existing ACARS applications & enable
introduction of new applications
CNS partnerships, as exemplified by the SITA/AENA agreement,
demonstrate a pragmatic way forward to enable ATN/CPDLC
introduction
SITA’s ATN Service will be shortly launched to meet Link2000+
Pioneer Project requirements
