controllers depending on the airspace in
which it is applied. It is also clear that the
objective is not to achieve interoperability
through the deployment of all technologies
in all aircraft.
This fundamental understanding was
largely echoed by several speakers at
the ICAO Forum, with IATA pointing to a
single avionics package and training, to
the importance of an appropriate flight
plan and to the need for solutions not to

be technology-driven but to be based on
operational requirements within a prearranged
and agreed institutional framework.
For IATA, the increased benefits of
interoperability and cooperation between
States/across regions are conditioned
by the existence of an integrated and
harmonised global ATM framework.
Pilots also stressed the global scale of
implementation, which must be simultaneous
where possible, and seamless
while allowing for flexibility.
In order to achieve interoperability on
a global scale, a first general step has
been taken by ensuring that SESAR
is compliant with ICAO guidance: the
performance orientation, with performance
target-setting, planning and transition;
the operational concept, which
refers to the ICAO concept; and the
Master Plan, which has been linked to
the global transition initiatives of the ICAO
ATM/CNS Global Plan. These links were
explained on the European stand at the
Forum and can be seen on the Master
Plan electronic portal (www.atmmasterplan.
eu).
It is the mission of the SESAR programme
(and SESAR抯 work programme already
makes provision for this), to take the
necessary steps to adapt worldwide
standards to cover the new functionalities
and supporting systems, and to
facilitate transition. We are aware that the
success of European developments can
serve as both a model and a catalyst for
other regions, which are also dependent
on global progress.
In this context, recent achievements
under the auspices of ICAO, such as
the performance-based navigation and
performance-based transition manuals,
or the adoption of AIXM v5, are significant
and encouraging steps in the right
direction. I would also like to take this
opportunity to praise the efforts of the
European experts involved in these
activities.
In turn, SESAR needs more ICAO material
to ensure that interoperability requirements
can be fully addressed. This is
especially the case for:
n information management (data
models, quality of service requirements,
sharing rules, distribution
process);
n the new flight plan/flight object necessary
to describe the trajectories;
n new procedures, in particular
for trajectory exchanges and
揷ontracts?
n data-link applications for trajectory
data exchange.
The validation of these requirements
should be a prerequisite for selecting
the future enabling CNS technologies,
thereby also limiting the proliferation of
system standards for similar uses.
The SESAR ATM Master Plan underlines
the importance of ICAO in the
drive towards the achievement of global
interoperability. In particular, we recognise
ICAO抯 leading role in the timely
delivery and effective application of
SARPs1 and PANS2 material based on
validated concepts and technologies.
This allows those regions with urgent
needs to progress at the pace required
by their traffic volumes/density, and
enables the establishment of synergies
across regions through the coordination
and harmonisation of plans. n

Aircraft fly around the world everyday.
During those flights they encounter
considerable changes to their environment.
They may fly through regions of high and low
traffic density, over oceans or deserts, yet
they always expect to receive the same level
of service from the ground.
To ensure that this basic requirement is
achieved, all Communication, Navigation
and Surveillance (CNS) interactions with the
aircraft must be identical. This in turn requires
standards which are globally applicable and
which ensure global interoperability.
Such interoperability is assured through
adherence to the standards set down
in the various ICAO Annexes.
