various standardisation bodies, such as
EUROCAE, the European organisation
for civil aviation equipment, or ETSI,
the European Telecommunications
Standards Institute. Working in close
cooperation with EUROCONTROL,
which is drafting the SESAR standardisation
roadmap, the S-JU would make
recommendations relating to areas
where it regards
standardisation
as appropriate;
it would also
support standards
organisations
in their
understanding of the needs and objectives
of the air transport industry. The
S-JU has now formally joined EUROCAE
and will seek to cooperate with other
organisations as appropriate. 揝ESAR
will also support these standardisation
bodies to the point where we could
actually contribute to the funding for
the development of standards,?adds
Peter Hotham. The intention, again, is
to 揾elp speed up the work,?he says.
Listen to the machine!
Beyond sheer equipment interoperability
and standardisation, the S-JU is also
mapping out ways to promote compliance
with the future ATM system and
processes. 揢sers won抰 see the benefits
of the new system unless they work
differently,?stresses Michael Standar. As
a prosaic example, his team are working
on procedures to ensure that information
is transmitted, acknowledged and
understood by the various operators in
the ATM chain. One of the major issues
with today抯 voice-based information
exchange processes ?the simple mutual
understanding of the different flavours of
English spoken around the world ?may
not disappear automatically with the
creation of a data-link-based system.
揕arge interoperability efforts are needed
to ensure that messages can be read
not only technically, but also semantically,?
comments Michael Standar. 揥e
must not ignore the human factor and
the way humans interact with the system.
Otherwise we can crate more hazards,?
he adds.
Europe and the United States aim at
delivering transformed, interoperable
ATM systems with enhanced capacity,
cost, safety and environmental performance
by 2020/25. Peter Hotham and
Michael Standar believe that successful
transatlantic collaboration will create
the momentum for a subsequent push
towards global interoperability. 揂irline
operators would object to facing
completely different methods of operation
when they leave the US or European
airspace. There will be an appeal from
the industry to ensure global consistency
and to convince the other regions of the
world to join in,?expects Michael Standar.
S-JU is anticipating that development by
promoting open and active cooperation
with international stakeholders. Europe is
developing a solution to avert a looming
regional capacity crunch ?but it is doing
so within a global perspective, with a
view to offering an equally appropriate
response once the issue arises elsewhere
in the world. n

NextGen: the US next generation
air transportation system
Our current national airspace system,
while considered to be one of the most
efficient in the world in handling massive
amounts of air traffic while maintaining
an outstanding safety record, faces limitations
in terms of its ability to grow and
adjust to a new and changing environment.
The basic problem: the system
relies on ground-based radar, which
dates back to the Second World War,
and voice, rather than digital, communication
between air traffic controllers and
pilots. It lacks the level of automation
we抳e come to expect in the 21st century
and has significant limitations in its ability
to support a growing aviation system.
Also, it does not easily accommodate
new technologies, which are essential
to allow for more energy-efficient and
environmentally friendly flight paths and
approaches.
the Federal Aviation Administration (FAA)
and other parties to the Joint Planning
and Development Office (JPDO) is to
make sure that international air traffic
management systems work in harmony.
In 2003, the U.S. Congress passed legislation
establishing the JPDO, which is
responsible for maintaining the NextGen
vision and integrating the efforts of the
five government departments charged
