papers were presented and published at international
conferences.
Analytical modelling has recorded a remarkable
advance at the theoretical level, incorporating
the inclusion of uncertainty in planning estimates.
A Markov Decision Programming model
was developed from collaboration between the
Centre and the University of California at
Berkeley applied to small-scale dynamic rerouting
problems. Referred to as the “uncertainty
region model”, it can summarise all uncertainty
factors in just one parameter for use in the
dynamic replanning process. Pending confirmation
with larger-scale problems to validate its
applicability in ATM, the results have been
extremely promising.
In addition to these encouraging results, valuable
progress was made in the definition and
control of procedures for the selection of students
and studies. The Annual Innovative
Research Workshop was attended by more than
50 scientists from over 14 Member States and all
were very interested in, and greatly appreciated,
our research activities. The Innovative Research
Advisory Board welcomed the investigation on
Aircraft Identification Tag and recommended
several improvements to the concept development
and analytical modelling work.
In 2003, four new PhD theses, one university
study and two new partnerships with national
research establishments were initiated.Thirty-six
papers were published in international conferences
and journals.
SOCIETY, ENVIRONMENT AND ECONOMY
(SEE)
Devised early in 2003, work in the SEE research
area is organised around four main threads:
Noise nuisance around airports;
Fuel burn and emissions;
Air quality issues around airports;
Sustainable aviation.
Noise nuisance around airports
Aircraft noise, despite being rapidly caught up by
local air quality, is still the largest source of aviation-
related complaints from people living close
to airports.
SEE has played a major role in the ECAC Airmod
working group responsible for rewriting ECAC
Doc. 29 – the guidelines for aircraft noise modelling
in Europe, now the “Interim Aircraft Noise
Model” for the European Commission Common
Noise Policy.The Centre’s role has been especially
prominent in the design of the noise and performance
database that will accompany the new
version of this document. To this end, a website
has been created that will give registered users
access to this data.

Fuel burn and emission
Recent research indicates that the effect of cirrus
cloud forming from aircraft contrails could be
having a significant effect on global warming
and climate change. In this context, the Centre
initiated a project late in 2003 called CONTRAILS
in cooperation with the European Space Agency
(ESA) to identify the relationship between
changes in cirrus and air traffic density.
Air quality issues
The issue of airport local air quality is becoming
more and more important. In partnership with
Lyon St Exupéry and Zurich airports, the Centre
focused on establishing a thorough airport emissions
inventory database with validation studies
and developments of a Geographical
Information System (GIS) tool to visualise the
three-dimensional distribution of the emissions
around an airport.
Sustainable aviation
In a two-phase study into the concept of sustainable
development in air transport, the Centre
considered in 2003 the notion of “sustainability”.
In the second and more challenging phase in
2004, the Centre will attempt to identify pricing
options and/or regulatory mechanisms consistent
with the notion of sustainability, which
could foster sustainable development.
Attitudes to Aircraft Annoyance around
Airports (5A)
The 5A project looks at how socio-economic, cultural,
age, status, education and situational factors
modify the way in which noise translates
into annoyance among residents around the
three study airports: Manchester, Lyon and
Bucharest. The attitudinal responses indicated a
reasonably high degree of consensus across the
three countries.
Flight efficiency and its impact on environment
Direct flight between departure and destination
airports offers significant savings in fuel and thus
environmental benefits. In conjunction with
the Performance Review Unit and the EUROCONTROL
Environment Domain, the ENV-KPI
project pursued the establishment of indicators
