for the first time ever, radar identification of a flight was
established and maintained without the assignment of
a discrete secondary surveillance radar code by air traffic
control.
As Mode S enhanced surveillance will continue its
expansion in several European States, the Agency started
to manage the European-wide coordinated allocation
of Mode S interrogator codes on behalf of ICAO for
the EUR Region. This process was undertaken in close
cooperation with national regulatory authorities, air
navigation service providers and radar manufacturers.
Preparing the way for ADS-B
Additional capacity will also be created through the
introduction of Automatic Dependent Surveillance –
Broadcast (ADS-B) systems, which will provide an accurate
and cost-effective surveillance capacity in areas
where it has hitherto been unavailable. EUROCONTROL
worked together with airlines, ANSPs, several airport
authorities and industry to verify feasibility and make
ADS-B implementation happen as soon as possible.
A number of the sites are located in countries where
ANSPs are already actively participating in ADS-B
CRISTAL trials: Austria, France, Germany, Greece, Italy,
Sweden, Turkey and the UK. Other sites are located in
Moldova, Norway, Romania, Spain and the Ukraine. The
Agency also initiated an ADS-B Pioneer Airlines project
to help airlines obtain airworthiness approval for their
existing ADS-B equipment. This will allow them to receive
an ADS-B-based air traffic control service.
Greater capacity through
improved traffic flows
EUROCONTROL’s Central Flow Management Unit (CFMU)
contributes to making the best possible use of available
airspace in Europe by providing air traffic flow and
capacity management, flight planning, airspace data
operation as well as data provision and reporting. The
activities which contributed most to capacity optimisation
over the year were: the management of air traffic
flow and capacity management (ATFCM) scenarios,
simulation studies, the AMON (Airport Monitoring)
experimental service and improvements in the management
of airport information.
In 2008, the CFMU set up AMON to ensure the compliance
of flight plans with airport slots during special events. It
was successfully tested during two special events: the
Monaco Grand Prix F1 motor race and the UEFA EURO
2008 soccer finals. The AMON service proved highly
effective in dissuading aircraft operators from undertaking
non-planned flights at selected airports during
the restricted periods. As a result of the positive evaluation
of the AMON service, the Agency will keep it available
for future special events. In addition, an impact
assessment will be carried out to evaluate the regular
use of AMON at a selected number of airports.
Traffic and delay trends at Maastricht Uac (2000-2008)
The CFMU also set up an ATFCM Simulation Cell with
a remit to study the impact of planned events on the
network with a view to optimising the applicable regulations
and adjusting ACC sector configurations accordingly.
Over the course of the year, about 15 simulation
exercises were run using the SIMEX tool developed by
EUROCONTROL.
During the year, the CFMU held several meetings with
stakeholders to agree on the ATFCM measures and
rerouting scenarios to be used to solve anticipated
bottlenecks. In 2008, the management of scenarios was
carried out on the main axes of traffic flows: the South-
West axis, the North-East axis and the South-East axis.
Capacity through
regional ANS services
With 1,534,825 flights handled over the period, air traffic
demand at the Maastricht Upper Area Control Centre
(UAC) remained stable in 2008. However, levels dipped
just below the previous year’s total, representing an
actual downturn of 0.4% over 2007. Over the summer
period daily peaks were higher than ever – 5,024 flights
were recorded on 4 July 2008, bringing the average traffic
volume during the summer season (May-October) to
4,540 flights per day.
Despite the additional delays recorded in December,
resulting from the extraordinary restrictions related to
the implementation of the new flight data processing
system, the Centre was able to improve punctuality
and achieve an en-route delay reduction of approximately
20% compared to 2007. In 2008, 96.7% of all
flights were unimpeded and the average delay per
flight was brought down to 0.5 minute (vs. 0.6 minute
in 2007).
