first time, the proposed SESAR programme involves air and
ground, and civil and military operators, legislators and
suppliers together in defining, committing to, and
implementing a Europe-wide programme.
This SESAR programme aims to eliminate fragmentation,
transform the system and synchronise different partners’ plans
and actions with resources. Its definition phase, a
EUROCONTROL/European Commission (EC)-funded project, is
conducted by a consortium established by 30 partners
(representing airspace users, airports, ANSPs and aircraft and
equipment manufacturers and suppliers) including the
Association of European Airlines (AEA), plus a similar number
of project associates (military, research staff, professional
associations, US industry). Its aim is to deliver the Master Plan
to transform the European ATM system and make it able to
meet the 2020 requirements.
In the meantime, short- and medium-term programmes will
exploit the current system’s maximum potential, while
planned research programmes should yield new ‘solutions’ to
S address a capacity shortage that is, otherwise, expected to
grow during the next decade. Planned operational
improvements that should meet requirements up to at least
until 2010 include enhanced airspace capacity resulting from
the Dynamic Management of the European Airspace Network
(DMEAN) programme, as well as increased sector productivity
through air-ground data link applications and automated
assistance tools for air traffic controllers. Related plans address
airport throughput and collaborative decision-making.
On the communication, navigation, and surveillance (CNS)
side, Miaillier points to programmed improvements, including
new flight-data processing systems, additional radio channels
and the prospective pan-European network services for
telecommunications. Improved safety and security
arrangements and the sharing of good practices will
complement these moves.
The vision is for “a high-performance ATM network for
2020” says Miaillier. Originally formulated in the EC Vision
2020 for aviation, design goals include an 80 per cent lower
accident rate, doubling of traffic capacity, and a halving of
aircraft noise and emissions. Targets are for 99 per cent of
flights to be delayed by less than 15 minutes and for
passenger handling to require no more than 30 minutes.
Essential SESAR constituents include standards driven by
performance requirements (rather than new technology),
gate-to-gate system integration, borderless airspace and
enhanced satellite technology. Other characteristics are
co-operative ATM (including four-dimensional trajectory
management, new automation ‘tools’, and assisted airborne
separation), System-Wide Information Management (SWIM)
and interoperability. Miaillier says that previously there has
been a mismatch between actual and potential application of
new technology that now can be overcome.
He emphasises the paradigm shift implied if European ATM
is to meet the needs of the next two decades. While historical
practice has been essentially procedural with estimated
aircraft locations, today’s radar-based activity ‘knows’ current
situations, while estimating planned positions. In future,
trajectory-driven systems will share existing and expected
aircraft locations. “Now there is a change in the information
available, but ATM remains a human activity.”
The European ATM Master Plan recognises converging
needs, and initiatives and requirements for co-operative

solutions. Given growing traffic and events such as increased
terrorism threats, Miaillier sees unprecedented challenges:
“Industry is conscious that [stakeholders must join the]
process to help technical capacity improvements and
economic investment.” The time and conditions are right to
“provide momentum to previous ideas”.
The major needs are to remove ATM fragmentation,
accelerate evolutionary responses, synchronise and integrate
plans (from research to operations), and synchronise
introduction of new procedures. Miaillier says SESAR supports
the SES legislation by technical and operational initiatives.
“SESAR is a cohesive programme for stepwise, performancedriven
implementation [that] addresses European needs and
global interoperability.” The SESAR programme is being
conducted through three sequential phases. The current
2005-07 definition phase involves the planning that will feed
into the 2008-13 development phase. This will be followed by
