investigate performance differences between
selected US and European air traffic control
centres and for benchmarking purposes in the
ATM cost-effectiveness reports. COCA will be
extended during 2004 to include a functional
model of ATC cognitive complexity.
Support to European enhanced flow management
operations
Several ATFM assessments were completed,
including an improved model for ACC optimal
configuration. A slot allocation algorithm alternative
to the first-planned-first-served rule was
completed and initial tests produced promising
results.
The study of a Collaborative Airline Interface
with ATFM (CAIA) was concluded through a
series of prototyping exercises at airline sites (BA,
KLM, SAS, Easyjet, SN Brussels Airlines) resulting
in feedback for the design of advanced CFMU
interfaces for airlines.

Tactical traffic management
One of the most promising elements of the
ATFCM strategy, as underlined by the
Performance Review Commission, will be the
development and implementation of the Tactical
Traffic Management concept. This will improve
traffic smoothing performance by complementing
the current ATFM system with real-time air
traffic synchronisation and dynamic negotiation.
Following the 2002 delivery of a draft operational
concept, prototypes were produced in
2003 to consolidate this concept by facilitating
the identification of appropriate measures and
the negotiation and communication of those
measures between different centres.
To further strengthen the development of this
concept, a TEN-T project was signed in
November 2003 with the European Commission,
resulting in the project called “Cooperative ATM
Measures for a European Single Sky” (CAMES). In
cooperation with Skyguide, AENA, DNA and
ENAV as well as the CFMU, it will validate the first
elements of tactical traffic management concepts
based on specific traffic flows. A series of
workshops with these key air navigation service
providers reviewed ATFM operations in the targeted
areas and assessed the suitability of the
proposed measures.
SECTOR SAFETY AND PRODUCTIVITY (SSP)
The main objective of the creation of the new
SSP research area was to consolidate all aspects
of controller-centred sector-level operations.
This includes air-ground integration applications
such as new ATC spacing instructions and others
which may transfer some workload from the
ground to the cockpit.
The objectives in this area are to clarify concepts,
carry out experiments and studies and examine
transition and implementation issues in order to
generate data in support of proof of usability
and operational coherence, business case development,
standardisation and regulation processes,
safety assessments and, ultimately, overall
implementation decisions.
In 2003, emphasis was placed on the development
of an overall integrated sector view rather
than a collection of individual independent functions.
Involvement in the Gate-to-Gate and OATA
projects has supported this.
A large number of experiments and studies
(described in the Experimental Centre’s 2003
Activity Report) were carried out by SSP in the
course of 2003. Some key results were obtained
in the following areas:
ASAS Package 1
Among the various ADS-B projects, SSP has
taken a particular interest in sequencing and
merging. Simulations (both ground and air-side)
continued to show positive results for this application,
which involves the use of new ATC ‘spacing’
instructions.The feasibility of the techniques
has now been demonstrated in the Terminal
Control Area (TMA) and final approach, showing
benefits that are recognised both by the controllers
and pilots involved in the experiments.
Datalink
Experiments to support initial Link2000+ implementation
(from both operational and technical
perspectives) have confirmed the feasibility of
the initial Link2000+ set of services. Simulations
involving more advanced datalink services have
clearly shown benefits for some services, but not
for others.
Work also continued on new controller tools and
the associated changes in controller working
methods. Particularly successful in 2003 were a
series of live shadow-mode trials involving automated
conflict detection. Further studies to
develop support for conflict resolution tools
demonstrated some new techniques and HMIs
associated with an arrival management tool.
