AIRPORT THROUGHPUT (APT)
The airport throughput research area (APT) was
established in 2003 as part of the Centre’s
realignment and in response to the prediction
that airports are going to become the most
constraining factor for European aviation. To
address these issues, the area has focused initially
on Collaborative Decision-Making (CDM) and
Wake Vortex – CDM to provide data commonly
usable by all actors at an airport and Wake Vortex
to improve runway utilisation.
Wake Vortex
The Time-Based Separations Project reported on
runway capacity calculation under various wind
conditions, indicating that 2 to 3 landings per
hour can be recovered in 15 knots headwind.
Controller tools and an initial hazard analysis
were delivered, together with a PC demonstrator.
WakeNet 2 Europe Thematic Network promotes
wake turbulence research to address existing
and foreseeable safety and capacity problems
caused by wake turbulence. Results from previous
studies showed a major improvement in the
knowledge of Wake Vortex phenomenon.
WakeNet 2 Europe will provide guidance for
complementary research and operational applications.
Leader of the development of operational and
system requirements in the field of ATC-Wake,
the Centre delivered operational requirements,
operational concepts and procedures together
with user and system requirements in August
2003. A 15% average increase in runway
throughput is expected.
Collaborative Decision-Making (CDM)
CDM pursued the development of more
advanced airport CDM applications and support
to initial implementation at a number of
European airports. Messages to exchange CDM
information between the CFMU and the airport
and the variable taxi time applications were
defined in 2003. Athens, Lisbon and London
Heathrow airports took part in implementation
trials. Other key airports such as Amsterdam,
Paris and Munich have also been discussing CDM
with EUROCONTROL and close cooperation is
foreseen in 2004.
A cost-benefit analysis study has been commissioned
and will, together with the CDM promotional
film and Implementation Manual, play an
important role in the introduction of CDM at all
major airports in the ECAC area.
Cooperation with the University of Aachen has
started to map airport landside processes and
establish state-of-the-art of research within this
domain.
INNOVATIVE RESEARCH (INO)
2003 saw great progress in the objective to
strengthen innovative research, with many
encouraging results.
Exploration of a new control paradigm based on
a large volume of airspace, linked to ACARE proposals,
has focused on the shift of controller
working practices in an adapted airspace.
Simulation has shown subsequent gains in
capacity while reducing the conflict-solving
workload, confirming the initial hypothesis that
larger volumes of airspace offer the possibility
for more organised responses to unpredictable
events in traffic planning.A follow-up project will
concentrate on the synchronisation of traffic,
from flow planning to tactical control and on
dual-mode of operations: large-volume (supersector)
and city-pair tube-control (sector-less).
Five papers were published at international conferences
on this topic.
On the advanced technology investigation front,
the study into the adaptation of digital watermarking
techniques for pilot-controller VHF
voice communication has provided remarkable
results that could open the door to significant
short-term applications. The Aircraft Identification
Tag (AIT) study demonstrated that aircraft
identification, e.g. call-sign, can be automatically
added as a digital signature to a voice air/ground
communication without any modification to the
existing equipment. Consequently, the aircraft
call-sign can be automatically detected through
VHF communications, thus enhancing security
protection with an encouragingly low message
error rates.
Also showing great potential is the study on the
applicability of Stereoscopic 3D visualisation and
multimedia interaction techniques for future
controller working positions. The human-in-theloop
experiment, assessing comparative accuracy
and time performance in 2D and 3D stereoscopic
environments, has shown that controllers
perform quicker with 3D stereoscopic displays,
without any detriment to accuracy. This positive
result reinforces initial expectations and has orientated
the study towards pilot-testing of an
application for airport tower control. Eight
