It became apparent that the skills and knowledge
acquired in the NMC had to be migrated
into the tactical phase of ATFCM operations. The
Tactical Network Coordinator (TNC) position was
created to assist in this and is responsible for the
global effectiveness of the ATFCM system within
the tactical area of operations.
The use of teleconferencing and e-conferencing
as an important media for Collaborative
Decision-Making (CDM) continued. In winter
2003, a weekly teleconference/e-conference
addressing the traffic for the ski season was
added to the SW Axis and North Atlantic Daily
conferences. Some tangible benefits were
derived from this process as regards the presentation
of traffic and the reduction of delays in
comparison with previous seasons.
Extensive utilisation of scenarios, including flight
level capping, alternative routing or rerouting
has continued. These are on the whole advisory.
There have been significant reductions in delays
in 2003 but aircraft operators are now beginning
to address the issue of service quality in terms
other than delay. As a result,we can expect more
criticism of such techniques as level capping,
early descents, etc.
The “abuse” of the system through false
Estimated Off Block Times (EOBTs) that was
reported in last year’s report was resolved
through the CDM process and resulted in a trial
procedure at Herakleon airport throughout the
summer of 2003. Initial results were positive
although the process was very resource-hungry.
The trial will be continued, and possibly extended
to other airports in 2004.
CFMU CLIENT CONNECTIONS
The CFMU clients,primarily aircraft operators, airport
handling agencies and air navigation service
providers can access the CFMU systems either
via the Internet or a dedicated network.The number
of clients with online access is constantly
increasing, particularly since the introduction of
ETFMS and the associated increase in accuracy of
real-time data. In September 2003, there were
1,659 active user accounts, which by February
2004 had risen to 1,916 – an average increase of
3% per month.
FLIGHT PLAN TRAFFIC
The general increase in air traffic during 2003 was
also reflected in the number of flight-plan-related
messages processed by the IFPS system and of
course the resulting increase in workload. The two
IFPS Units processed a total of almost 14 million
flight-plan-related messages during 2003, an
increase of 5.68% compared with 2002.The number
of flight plans generated from RPL has increased
slightly,its percentage remaining at just under 50%.

played and will remain valid in real time. This
facility will be made available during 2004, after
which new functionalities will be added, such as
flight plan filing assistance, taking advantage of
the dynamic graphic display capabilities.
Another step in the same direction was the introduction
of the CFMU Interactive Reporting facility
(CIR), which gives online access to a great variety
of reports based on the information stored in
the CFMU data warehouse.
Another major milestone was the introduction of
the new Unix-based Environment system which
offers new facilities for ATS data maintenance and an
improved user interface.An important side effect for
cost saving is that,with the start of operations of the
new Environment system, the last milestone in the
mainframe phase-out programme was achieved
and the equipment could be switched off early in
2004.
In 2003, 81% of the messages received by IFPS
were processed automatically, a slight increase
compared to 2002. It is worth noting that as the
