Laboratory at the EEC. This is a significant step
towards the network of joint EUROCONTROL/

Simulations were run to evaluate arrival and departure
management facilities for the Italian and
Swedish ANSPs. Live trials were also conducted to
evaluate medium-term conflict detection tools, with
a final set of exercises run at Maastricht UAC.
Results show benefits in en-route sectors but are
less conclusive in sectors dealing with climbing
and descending traffic.
Technical aspects of Automatic Dependent
Surveillance-Broadcast (ADS-B) implementation
were investigated, showing substantial benefits for
surveillance performance.
A significant contribution was made to the
Mediterranean Free Flight project. A third series of
real-time simulations was completed and extensive
flight trials were planned. Partnerships were
established with the EC乫s Northern Europe ADS-B
Network Update Programme (NUP-2) and South
European Pre-Implementation ADS Program
(SEAP), with the international requirements focus
group and in EUROCONTROL/FAA cooperative
programmes.
To integrate safety concerns over separation management
issues, a safety plan was written with
both a top-down and a bottom-up approach, with
special attention to the safety of live trials.

2004 Highlights (cont乫d)
The new Operational Concept Validation
Methodology was developed in the framework of the
Gate-to-Gate project. Validation is now under way.
Airport throughput
The results of an initial feasibility study for the
Time-Based Separation project were delivered and
are based on rapid prototyping and development
of business cases for risk evaluation. Significant
results were achieved during 2004:
仭 Initial theoretical calculations showed that, on
average, around three arrival movements per
hour could be recovered with Time Based
Separations (TBS) at a typically large European
airport in headwind conditions.
仭 A wake vortex encounter risk study concluded
that the use of TBS minima appeared to offer
significant capacity benefits without increasing
the risk of wake vortex encounters along the
glide slope when operating in headwinds.
仭 Cost-benefit analyses indicated that implementing
TBS at Frankfurt would not be beneficial
because two parallel runways are used for
arrivals in visual meterological conditions.
However implementation at London Heathrow
would bring significant benefits. There was no
requirement for new airborne equipment.
仭 Controller working methods and procedures,
together with proposed support tools, were
drawn up and tested in a series of rapid prototyping
simulation runs. These indicated that the
concept is feasible and understood and
accepted by controllers. Two support tools proposed
and further developed during the exercises
. Intelligent Time Vectors (ITV) and Target
Positions (TP) . were seen to be complementary,
depending on the phase of the flight: ITV was
more appropriate when the aircraft was in the
maneuvering area and TP once the aircraft was
established on the glide slope.
Considerable effort was devoted to analysing
wake vortex separation requirements. This took the
form of managing the European WakeNet Working
Group, attending meetings in the USA, membership
of the Light Detection and Ranging Working
Group, participating in the FAA-NASA ConOps
Team and issuing requirements for applied
research topics. A survey on wake vortex detection
technologies was also carried out.

EEC: PATHWAY
TO THE FUTURE
Long-term investigation
Long-term investigation in 2004 focused mainly on
preparing the ATM R&D Master Plan and participating
in the ACARE SRA, which takes a holistic
and comprehensive approach to the air transport
system and includes operator and service provider
perspectives.
The initial vision aims to define the operating environment
for deployment within the 2017 timeframe,
based on the assumption that research activities
will be completed in 2012. At this stage, the
longterm vision remains essentially conceptual.
For the mid-term, special focus will be placed on
integrating the results of safety assessment.
Research will focus on:
仭 Airspace design and management, incorporating
technological developments for air/groundintegration
and four-dimensional precision trajectories.
