from straightforward, and can often negate the savings of choosing COTS.
 Flexible yet highly secure communications
The importance of security and data protection cannot be overemphasized in today’s highly-connected aircraft-ground
IP environment. Airlines simply cannot afford to import the risks often associated with generic IP ground networks into
the aircraft domain.
At the same time, new cockpit systems require an environment where communications with airline ground systems and
authorized third parties can take place reliably, transparently and securely. For commercial and practical reasons,
ground-based systems and passenger cabin applications must also be able to share communications and IT
infrastructure while being segregated from critical airline operational communications.
 Robust, dependable services
New systems and applications must not only coexist with current ACARS services, they must continue to offer
dependable airline-grade service which also provides a solid platform for more complex applications. That means being
able to operate within the confines of long-standing, rigid procedures, while at the same time accommodating the
coexistence of diverse aircraft fleets. Airlines will need to equip aircraft with the necessary avionics while also upgrading
ground systems and corporate networks to ensure that bandwidth, security, data protection and authentication are all
taken into account.
 Intelligent network services for cockpit IT
New generation aircraft applications using cockpit IT platforms will generate and exchange much greater volumes of
data than ACARS applications, making smarter ways of managing information essential. Airlines need the tools to
control how, where and with whom aircraft information is exchanged, in line with their unique business requirements.
That includes the ability to prioritize and pre-empt information exchanges to ensure that time-sensitive data is sent
ahead of non-critical data, or that non-critical data is exchanged only when the most cost-efficient links (such as
wireless links at airports) are available.
Faced with such an array of complex considerations, as well as the requisite coordination with multiple suppliers and
organizations around the world (all of which are in various stages of preparedness) to ensure interoperability across the
entire route network, it’s not hard to see why the transition to new generation platforms will demand a coordinated,
holistic approach to technology, infrastructure integration and business process transformation – delivered by a partner
that really understands the air transport business.

NEW GENERATION COCKPIT IT INTEGRATION 7
As the leading global provider of aircraft datalink services, SITA is helping
airlines make the transition to new generation communication systems.
A purpose-built platform that complements the existing ACARS service and provides a migration path for new and future
aircraft communication needs.AIRCOM IP will transparently integrate new generation aircraft cockpit IT systems with
airlines’ ground IT infrastructure; manage connectivity to all aircraft; and provide seamless links to authorized third parties –
all within a flexible and secure environment adaptable to airline demands. AIRCOM IP will match the best features of the
AIRCOM ACARS service while providing a platform to exploit advanced functionality and applications of new generation
aircraft cockpit IT systems.
By securely and transparently integrating aircraft cockpit systems into an airline’s ground IP network, AIRCOM IP
will make the open IP world a safe place for aircraft to communicate.
The following AIRCOM IP components are being gradually rolled out to suit airlines’ needs and schedules as they take
delivery of and begin operating their new aircraft.
AIRCOM IP Integration Solutions
SITA’s AIRCOM IP integration solutions are geared to assisting airlines planning, implementing and managing the integration
of new cockpit IT systems with existing ground IT infrastructure.
AIRCOM Customer Link Manager: An airline application integration solution built on SITA’s market-leading AIRCOM
Server, AIRCOM Customer Link Manager allows end users to manage legacy ACARS and new IP links over a single
platform. It also integrates airframers’ gateway communication modules, eliminating the need to manage multiple
communication systems across diverse fleets, and enabling ground applications such as e-Charting to communicate
transparently with different aircraft types.
AIRCOM IP Integration Services: SITA also offers professional services to support airline design and validation of ground
