Radar-derived data expands
The area from which the CFMU is receiving radarderived
data for the ETFMS continued to expand
throughout 2004. Around 80% of ECAC flights are
now updated after their departure using this information.
Operational utilisation of this information has
advanced and has enabled an improved assessment
of traffic demand. More than half of the flights
are now adjusted before their departure, thanks
both to the accuracy of the data, and to the commonly
agreed Flight Activation Monitoring procedures,
contributing to better capacity management.
During 2004, CFMU systems have further evolved
towards offering more services to the remote user
community.
仭 The new graphical interface has been fully validated
and accepted by the different categories
of users and will enter into service in 2005 at the
different locations.
仭 The distribution of data from the ETFMS has
also been prepared and is ready to be provided
to ANSPs willing to receive them.
仭 The exchange of information with airports has
been thoroughly assessed to make it effective
and to allow airports and the CFMU to work
more closely.
仭 The new architecture for the ENV data management
system has allowed the decommissioning
of the mainframe computer and better sharing
of information, preparing the CFMU for further
development of airspace management.
In June, the CFMU put its new message gateway
infrastructure (ANg1) into operational use. ANg1
includes all the properties of the ECG, the EATMP
Communications Gateway, but surpasses its functional
scope by far.
The CFMU made major investments during the
year to improve the security of its systems, by better
isolating operational platforms and enhancing
access control systems. These improvements
were made in line with recommendations made by
the Internal Audit.
Policy and Strategy plan
In continuing the ATFM action plan, the CFMU has
developed, together with its stakeholders, a
Strategy for ATFCM that has been approved by the
EUROCONTROL Commission. As a follow up, the
CFMU Evolution Plan has been approved by the
European ATFM Group. Both documents indicate
the common views for the development of ATFM
and the CFMU over the next 15 years.

The Central Route Charges Office (CRCO) has
been operating since November 1971 to provide
EUROCONTROL乫s stakeholders with an efficient
cost recovery system that funds air navigation
facilities and services and supports the development
of the European air traffic management system.
In 2004 the CRCO collected charges on
behalf of 31 Member States
The CRCO乫s mission embraces four objectives:
仭 Integration with EUROCONTROL strategy;
仭 Guiding the system乫s stakeholders;
仭 Enhancement of the quality of the services
provided;
仭 Reduction of administrative costs.
The CRCO also provides additional services to
Member States, including the calculation, billing
and collection of terminal charges. Non-EUROCONTROL
States can also benefit from its expertise
on a bilateral basis.
Flight messages processed
and distances flown
Over 8.61 million flight messages (IFR flights only)
were processed in 2004, an increase of 4.8% over
2003.
The number of kilometres flown in the airspace of
Member States for which route charges were calculated
was 7.19 billion km, 7.0% more than for 2003.
